The Low Down on Spondylosis in Dogs
Here at My Pet Nutritionist, we help pet owners with a host of different health conditions. One we see from time to time, is Spondylosis in dogs. Us humans can get Spondylosis too, but it tends to be more common in our canine companions than it does in their owners. This blog post aims to help you get a better understanding of Spondylosis in dogs, including what it is, how to spot the signs and symptoms, and how you can support the body naturally. What is Spondylosis? Spondylosis, called Spondylosis deformans in the veterinary world, affects the spine; more specifically, the vertebrae – the bones that make up the spine. It’s a degenerative condition, which means it gradually gets worse as the patient ages. Those with spondylosis have bony spurs growing on their vertebrae, known as osteophytes. But why are these growths bad news? The vertebrae protect the spinal chord – probably one of the most important parts of the body as it sends signals between the brain and the rest of the body, and vice versa, and ais also involved in reflexes and coordination. The body spurs growing on the underside of the vertebrae can rub on the spinal cord, causing damage, which then has a knock-on effect to the dog’s sensory capabilities, and ability to move freely. Spondylosis can be widespread, with bony spurs forming along the entire spine, or localised, where they only form in one or two spots. It is most commonly seen in the lower spine, AKA the Lumbar Region, as well as hips and tail. In particularly bad cases, bony spurs can fuse vertebrae together, making mobility tricky. Spondylosis is quite common in aging dogs, especially those who are heavier set, such as giant breeds, or breeds with cobby bodies, and short legs, but it can happen at any age and breed, depending on the cause, which we will look at shortly. The most commonly affected breed is the Boxer, where estimates suggest around 70% of elderly individuals over the age of 9, have been diagnosed with the disease. Findings Here Symptoms of Spondylosis The somewhat strange thing about symptoms when looking at a potential diagnosis of Spondylosis, is that there are very few clinical signs presented, especially not those specific to the condition. Some symptoms you may notice include: Spinal pain: hunching of spine, lameness, unwillingness to walk, difficulty laying down and standing up, general reduction of mobility Behavioural changes: your dog may become more reactive due to pain, and the fear of being hurt by another dog bumping them. Yelping when specific areas are manipulated Lethargy General weakness and stiffness Reduced appetite If your dog is displaying these signs, there could be a number of potential spinal issues, so it’s important to consult your veterinarian to grasp a better understanding of the exact issue your dog is having. Causes of Spondylosis So why does Spondylosis occur? It can be a natural part of the ageing process – just through general wear and tear of an older dog. Another cause of the development of Spondylosis, is trauma to the spine from injury, whether it’s minor trauma, like a bump to the spine, a wobbly landing from a higher surface, or repeated over-use of the spine (often seen in sports dogs who do the same movement repetitively), to major trauma such as having been hit by a car, or having had surgery to correct IVDD. A third potential cause of Spondylosis, is genetic predisposition. There are not many predisposed breeds, but the most commonly seen tend to be Boxers, German Shepherds, and Flat Coat Retrievers. Spondylosis can also form as a secondary disease! Between the vertebrae of a healthy dog, lays soft tissue. This enables the discs to act as shock absorbers, and softens impact, keeping the vertebrae separate. There is a degenerative disc disease, previously mentioned in its abbreviated form, IVDD (Inter-Vertebral Disc Disease), in which the tissue between the vertebrae wears away, leaving bone to rub on bone, prompting the formation of bony spurs to re-stabilise the joint. Findings Here Diagnosing Spondylosis As there is usually a lack of obvious symptoms in cases of Spondylosis, it can be tricky to pinpoint a test for it. If your dog is experiences clear signs of back pain, or even just at the vet for their annual health check where the dog displays possible signs of pain, the vet will use your dog’s medical history records to look for potential missed signs. They will perform any neurological and orthopaedic examinations they feel are necessary, and go from there. Your vet will typically want to rule out any other potential health issues before testing further for Spondylosis. A canine physiotherapist may be able to give a better look into mobility and how your dog’s gait is affected through a video analysis. This may be done through referral; however many allow the owner to book directly in with them to discuss the video, and their findings. Once your veterinarian has ruled out the potential for other, perhaps more common health issues, he or she will book your dog in for an x-ray of the spine, which includes the chest and abdominal cavities, naturally. X-rays tend to give a definitive answer as to whether the dog has Spondylosis or not, due to the visibility of bony spurs on the vertebrae. Less commonly, a vet may recommend an MRI scan – these tend to show potential spinal cord damage as opposed to the bony spurs themselves, which can be an important part of recommending the correct treatment. This procedure is usually carried out on referral with a neurologist. Findings Here Conventional Treatments There is actually very little a veterinarian can do in the event of a dog having Spondylosis, as every individual is different. The treatment plan is heavily based on symptoms the individual’s dog is showing, now a generalised treatment plan, which would be the same for all sufferers. Pain medication is regularly prescribed for those suffering
2 Types of Autoimmune Arthritis
Here at My Pet Nutritionist, we see a lot of arthritis cases. There are numerous types of arthritis in existence, some of which can be autoimmune responses. We thought we would put together a short guide on the two most commonly seen types of autoimmune arthritis; Immune-Mediated Polyarthritis and Rheumatoid Arthritis. What is Autoimmunity? Autoimmunity is sadly fairly common in both humans and pets and is often overlooked. When an individual has an autoimmune disease, the immune system releases antibodies and T-Killer Cells (cells of the immune system which target and kill cells infected with viruses and cancers) even when they are not in the presence of a necessary target, which causes them to attack normal, previously healthy parts of the body. In layman’s terms, the body attacks itself! Autoimmunity can be linked to Leaky Gut, and Leaky Gut can be linked with arthritis. Read our blogs on these topics below! The Connection Between Leaky Gut and Autoimmunity – Part 1 The Connection Between Leaky Gut and Autoimmunity – Part 2 The Link Between Leaky Gut and Arthritis Immune Mediated Polyarthritis Immune Mediated Polyarthritis (shortened to IMPA) is a painful degenerative joint disease. The term ‘immune mediated’ refers to a group of conditions which are caused by abnormal immune system activity, often due to upregulation of some immune cells, causing the body to attack itself. Symptoms of IMPA include: Pain and swelling in multiple joints Fever Lethargy General stiffness Weight loss Difficulty standing for long periods Enlarged lymph nodes Nausea, vomiting and diarrhoea One of the causes of IMPA, is infection of Leishmania. Leishmaniasis is a parasitic disease, where the host is infected with Leishmania, which is spread by sand flies. It is not present in the UK, bar in imported dogs, or those who have travelled abroad, and contracted it there. We see many cases in rescued foreign street dogs. The synovial fluid (the fluid located between joints of all mammals) of the dogs affected in a study, was tested, and found to have the inflammatory markers typical of a dog suffering with IMPA. All other pathways of IMPA were ruled out. Findings Here Vaccine Induced IMPA is probably one of the biggest risks, and one often overlooked during diagnosis of IMPA. There are various reports of cases whereby dogs have developed IMPA within 3 weeks post vaccination. Minimally vaccinating is essential to reduce this risk! Findings Here Findings Here One study based in Canada, discusses the various clinical abnormalities which accompanied IMPA in various IMPA positive dogs. These clinical signs included leukocytosis (increased white blood cell production), nonregenerative amaemia (lack of red blood cells due to reduced activity by the bone marrow), high alkaline phosphatase (ALP in blood tests), and hypoalbuminemia (disrupted albumin production, resulting in blood vessels drying up). There was no common age range between cases – cases were present from all ages; young to elderly. Findings Here Rheumatoid Arthritis Rheumatoid Arthritis (shortened to RA) is an autoimmune related degenerative joint disease. It’s symptoms include: Joint pain and stiffness in numerous joints Swelling in joints Weight loss Fatigue and lethargy Loss of strength Those suffering with RA often do so in a mirrored fashion – the pain will usually be the same on both sides of the body; both knees, both hips etc. RA can be triggered following infection of the bacteria Borrelia burgdorferi, which is transmitted from infected ticks to host; you may be more familiar with the term ‘Lyme Disease’. Findings Here During drug trials for this disease, where RA is concerned, a combination of pharmaceuticals were required to have any effect, as opposed to any of the individual options used in the trial. Findings Here Part of the immune system contains the Dog Leukocyte Antigen (DLA) Complex – this is a part of the immune system which distinguishes the body’s proteins from foreign proteins, viruses and bacteria. Within this complex, lays numerous alleles (pairs of genes – one from each of the dog’s parents), including the DRB1 allele, which is said to influence the susceptibility of an individual to be subject to developing RA, if it contains a certain amino acid. Findings Here A protein called Zonulin plays a part in Rheumatoid Arthritis (RA). It is synthesised by cells in the liver and intestine, and it’s roll in the body is to regulate the gut permeability, specifically Tight Junction Barrier Cells within the gut wall. When Zonulin is overrepresented, the gut permeability cannot be controlled, and allows useful and harmful substances to enter the blood stream, which are then detected as threats by the immune system. The upregulation of Zonulin, paired with the downregulation of Tight Junction Barrier Cells, causes more leakage of particles into the body, which in turn causes major inflammation throughout the joints in the body, sometimes resulting in Rheumatoid Arthritis. As with other autoimmune conditions, specific strains of good bacteria in the microbiome being leaked and attacked can cause the onset of RA. Findings Here Findings Here Findings Here Supporting the Body Gut Work Due to the relation between autoimmunity and Leaky Gut, its essential to keep the gut in good condition. Supplements such as Marshmallow Root, Slippery Elm or glutamine are great for this, especially paired with a good, clean probiotic to help recolonise the gut. Findings Here Findings Here Findings Here Diet Ensure you are not feeding any pro-inflammatory foods! High carb, processed diets like dry food are very pro-inflammatory and will add to the body’s inflammatory response. Stick to a fresh diet, whether it’s raw or cooked. It’s also imperative to keep on top of any allergies – both food and environmental. When we keep on top of allergies, and remove allergens
The Link Between Leaky Gut and Arthritis
It seems an odd connection; gut health, and arthritis, but the two are connected in multiple ways. We see a lot of patients here at My Pet Nutritionist, suffering from Leaky Gut, and/or arthritis. Read on to learn more about the connection between Leaky Gut and Arthritis! What is Leaky Gut? The condition is growing more and more common in both us humans, and our canine counterparts, and can lead to some pretty serious health issues, long term. The name ‘Leaky Gut’ does somewhat give the game away, but let’s look deeper into what actually happens in the gut of a normal dog, compared to one with Leaky Gut. In healthy individuals, after eating, the food passes through the gut. The gut consists of the stomach followed by the small intestine, followed by the large intestine (known as the ‘colon’), through which nutrients from the digested food are absorbed, before the waste is pushed out through the rectum, then anus. To enable a large surface area, for optimum nutrient absorption, the small intestine is lined with small finger-like structures called villi, which themselves are covered in even smaller finger-like structures, known as microvilli. The gut also houses lots of good bacteria to aid digestion – the colonies of good bacteria, along with yeast cells, any viral particles, or parasitic burdens, are collectively known as the‘microbiome’. The gut wall is extremely thin, to allow efficient nutrientabsorption. The cells lining the gut stay close together, and are supported by the interactions of immune cells, and good bacteria in the gut. In those suffering with Leaky Gut, inflammation occurs in the gut for various reasons, which causes the tight intestine wall to permeate, creating microscopic channels between the cells. Proteins/partially undigested foods then leak out through these channels and are detected by the immune system as a threat, causing a histamine response to occur, which is why one of the most common symptoms of Leaky Gut, is food intolerances. Other symptoms of Leaky Gut include: – Autoimmune Diseases – Issues with stools or sickness – Joint issues – Yeast – Problems concerning other major organs in the body – Hypothyroidism – Changes in behaviour; often anxious behaviour, and short tempered behaviour Possible Causes of Leaky Gut include: Over-use of vaccines; the adjuvants may damagethe gut flora Use of certain pharmaceuticals – Flea, tick, and worm medications; they disrupt the gut microbiome by not only eradicating the visiting parasites (or often lack thereof), but the good bacteria too. – Antibiotics; these wipe out the good and bad bacteria – Antihistamines; these can interfere with the production of mucus in the gut, and can also interfere with the proper functioning of Diamine Oxidase (DAO), which is the enzyme responsible for breaking down, and removing histamine from within the gut. – NSAIDs and Steroids; these can cause ulcerations in the gut and interfere with mucosal production. SIBO and Yeast overgrowth; Small Intestine Bacterial Overgrowth and Yeast damage the gut lining Diet; feeding a dry food diet may put stress on the gut. Kibble can sometimes contain Glyphosate, which is an antibiotic herbicide and is toxic, as well as very damaging to the gut. Diets inclusive of legumes and other high-lectin content pulses, nightshades and vegetables may contribute to Leaky Gut as lectin causes poor gut integrity. Microscopic moulds often found on kibbles, known as mycotoxins can also bedetrimental to gut health, contributing to Leaky Gut. Stress can have a huge effect on the gut integrity, as stress leads to inflammation Ageing; as our dogs age, the microbiome becomes less diverse which leads to gut damage. Findings Here Findings Here Findings Here Findings Here Read our full Gut Dysbiosis blog here! What is Arthritis, and How is it Connected to Leaky Gut? Arthritis is a disease caused by chronic inflammation of the joints. There are numerous types of arthritis, from Osteoarthritis to Rheumatoid Arthritis to Septic Arthritis. Let’s take a look at these types, and their connection with Leaky Gut. Osteoarthritis Osteoarthritis is the most common type of arthritis seen in our pets, and it is especially common in the later years, or following trauma. Other names for osteoarthritis are Degenerative Joint Disease, and Osteoarthrosis. Osteoarthritis affects the body’s synovial joints (these are the joints where a smooth layer of cartilage covers the end of each bone associated with the joint) as well as the tissues around them. It can be a crippling disease, but there are some herbal supplements which have been proven to benefit those suffering from it. Read about these here! The gut isn’t the first thing most people think of when looking at internal associations with osteoarthritis, but the gut-joint axis is very much affected! Like all types of arthritis, inflammation is a huge part, which is where Leaky Gut comes into play. When ‘foreign’ particles are leaked through the gut wall, the body’s natural response is highly inflammatory. The pressure on the body from this inflammation causes an increase in risk of Osteoarthritis. Equally, the gut-brain axis may be affected by the pain and stress caused by the Osteoarthritis, causing poor gut motility, and increased permeability causing systemic inflammation. Findings Here Studies show that building intestinal mucosal immunity, and repopulating the gut, has positive affects on those suffering with Osteoarthritis, as well as helping to prevent it. Findings Here Having a highly permeable gut also leads to increased transportation of microbes, including cytokines, such as lipopolysaccharide (LPS), particularly in overweight individuals. LPS is known for inducing inflammation, and in many studies it is found in unexpectedly high amounts in the serum around the affected synovial joints. Findings Here Findings Here Findings Here Rheumatoid Arthritis Rheumatoid arthritis is an autoimmune inflammatory joint disease. Multiple joints are often affected at the same time, and symptoms not only include swollen, warm joints and joint stiffness, but also fatigue and loss of appetite. The animal model of Rheumatoid Arthritis is called Collagen Induced Arthritis, for which many studies were originally carried out on mice. Findings Here Findings Here A protein called Zonulin plays a
4 Times You Don’t Want To Feed Veg To Your Dog
If you have followed us here at My Pet Nutritionist for any length of time, you’ll know that we’re great advocates for the inclusion of veggies for their prebiotic and fibrous benefits. But there are also times where we would avoid certain veggies. Keen to learn more? Read on. Nightshade Vegetables and Arthritis Some believe that the solanine contained in nightshade vegetables like bell peppers, tomatoes and potatoes may increase levels of inflammation in the body. Whilst there is disagreement over the mechanism, humans suffering with arthritis often report a worsening of symptoms after eating nightshade vegetables. There is one school of thought that it could be more to do with a sensitivity to the food, which results in an inflammatory response, contributing body wide circulating cytokines. Whilst nightshade veggies are a great source of certain nutrients, there are other foods which can provide these and so if you notice a worsening of arthritic symptoms, it’s an easy change to make. Natural Arthritis Guide Lectins and Should My Dog Eat Them? Goitrogenic/Cruciferous Veggies in Thyroid Issues The thyroid gland produces three important metabolic hormones, thyroxine, triiodothyronine, and calcitonin. Thyroid stimulating hormone (TSH) produced by the anterior pituitary gland controls the production of these hormones. Iodine, derived mainly from sea-foods or consumed in the form of iodised salt, is utilised for producing T3 and T4 hormones. T3 and T4 hormones affect every cell and organ in the body. They regulate the rate at which the body uses energy, which subsequently affects weight loss or gain. They raise or lower body temperature. These hormones influence the speed at which food moves through the digestive system. They affect brain development and also control the way muscles contract. Common thyroid disorders in our pets include hypothyroidism and hyperthyroidism, meaning the thyroid is either under-active or overactive. Ultimate Guide: Hyperthyroidism Ultimate Guide: Hypothyroidism Goitrogens are plant chemicals that can decrease the production or activation of thyroid hormone, meaning they slow thyroid function. These foods are commonly known as goitrogenic, which means they contain substances which slow the thyroid’s ability to uptake iodine. If eaten in excess, these foods interfere with the efficient function of the thyroid gland. The strongest goitrogens are soy products, but moderate inhibitors include: Broccoli Cabbage Kale Cauliflower Brussels sprouts All/Starchy Veggies in Yeast Issues Around 150 strains of yeast are thought to utilise starch as a sole carbon source for aerobic growth. In short what this means is starch is food for yeast! Starch, or amylum, is a complex carbohydrate that exists in many foods, including grains, vegetables, and fruits. Sources of starch are primarily: Maize Tapioca Wheat Potatoes The extraction of pure starch from food produces a white, tasteless, and odourless powder that doesn’t dissolve in cold water or alcohol. Starch is a natural polymer, or polysaccharide, meaning that it is a long chain comprising one type of molecule. Starch consists of glucose molecules. It can occur in two forms: amylose and amylopectin. You may be familiar with this wording as amylase is a digestive enzyme which helps break down starch. Yeast or candida is an opportunistic fungal pathogen but a normal part of the gastrointestinal flora and genital tracts. The issue is when there’s an overgrowth. If we are tackling an overgrowth, the last thing we want to do it continue feeding it and as you’ve now realised, starch is a great food source for yeast! Is Your Dog A Yeasty Beasty? All Veggies in the Case of An Elimination Diet When we are supporting a dog with digestive issues, we need to know exactly what is contributing to their symptoms. For this reason, we would avoid feeding all vegetables when running an elimination diet. Just like a dog can have a sensitivity to a certain meat type like chicken or beef, they can also have a sensitivity to fruits and vegetables. It’s important to remember that an elimination diet is a diagnostic tool – not a long-term lifestyle and in some cases, a means to give the immune system a welcomed break. In running an elimination diet, we follow the 4 R’s. – Remove – remove offending foods, one at a time and note changes in symptoms. Quite often, even offending foods can be reintroduced at a later stage. – Repair – support immunity and gut healing with ingredients like slippery elm, de-glycerised liquorice, glutamine, and N-acetyl-glucosamine. It is also important to consider how existing medications are affecting gut healing for example, steroid use impairs intestinal absorption which is linked to several gastrointestinal dysfunctions. – Restore – as the microbiome is key in the development of the immune system, supporting this is essential, however, the introduction of specific pre and probiotic foods is often best left whilst we get to the root cause. – Replenish – indigestibility of food proteins can also contribute to their antigenic nature, so consider any long-term medication use including proton pump inhibitors which affect gastric acid secretion. Ensuring HCL, pepsin and digestive enzymes are in good supply will help get the digestive system back to doing what it does best! Elimination Diets For Dogs We can’t deny the fibrous benefits of many vegetables along with their nutrient content, but when we are tackling a specific health issue in a pet, we must prioritise. We can often get those benefits in other ways if we think outside of the box. If you would like any support with your pet’s health and some outside of the box thinking, then please check our services to see how we can help. Thanks for reading, MPN Team
Do Herbs Have a Place in Canine Osteoarthritis?
Osteoarthritis is a common clinical and pathological endpoint from a range of joint disorders that ultimately lead to structural and functional decline of the joint with associated lameness and pain. A multimodal approach is necessary to support your dog who sadly suffers with osteoarthritis, but we thought we’d take a look at the evidence for any herbs that have supported this chronic condition. What is Osteoarthritis? Osteoarthritis, a common pain-causing condition of synovial joints, affects millions of human and non-human animals worldwide. These non-human animals include our trusty dogs. Osteoarthritis, also referred to as osteoarthrosis or degenerative joint disease, is a disease of the entire joint organ, including all its associated tissues, but is most frequently associated with the loss and dysfunction of articular cartilage. Risk Factors for Osteoarthritis: In humans, reported risk factors for the development of osteoarthritis are both systemic and local causes including genetics, age, sex, obesity, previous joint trauma, along with underlying diseases such as cruciate ligament rupture. Recent literature has indicated that up to 20% of dogs over 1 years old suffer with osteoarthritis. Findings Here Primary Vs. Secondary Osteoarthritis Primary osteoarthritis is described as largely idiopathic but can be associated with several risk factors including aging and obesity. Secondary osteoarthritis, where underlying disease processes or injuries play a role in the development of osteoarthritis, is believed to be the most common form in dogs. Secondary osteoarthritis is considered to have a genetic component exacerbated through aspects of lifestyle that impact body condition, such as diet and exercise. Disease processes and pre-existing conditions often influence the development, for example cruciate ligament disease is a common cause of pelvic limb lameness and can result in osteoarthritis development in breeds of all sizes. In addition, dysplasia, commonly occurring in the hip or elbow, describes the failure of normal joint formation during development and can lead to joint conditions causing pain and lameness, and can subsequently progress to osteoarthritis. To understand if any herbs could support this condition, we first need to establish its pathology. The Pathology of Osteoarthritis Osteoarthritis is characterised by joint cartilage degeneration, changes in the underlying bone and synovitis. In addition, there is an increase in pro-inflammatory mediators which promote immune responses, increase oxidative stress, inhibit collagen and proteoglycan synthesis, and diminish chondrocyte proliferation. Furthermore, MMPs are produced which induces the degradation of articular cartilage. For the most part, these changes result in pain, joint stiffness, loss of flexibility, tenderness, grating sensation, bone spurs and swelling. If we are to support this condition, we are looking to modulate inflammation, tackle increased oxidative stress and support the synthesis of those compromised compounds where possible. In turn, we are looking for a reduction in pain and symptoms with an improved quality of life. Herbs for Osteoarthritis (OA) in Dogs Boswellia spp. Boswellia, also known as frankincense, has been used for centuries in traditional Ayurvedic medicine. This herb exhibits anti-inflammatory activity. One clinical trial found that oral supplementation of Boswellia extract for more than 4 months significantly improved physical function by reducing pain and stiffness in OA patients compared to placebo, without causing serious adverse events. Majeed et al. found that OA patients receiving oral B. serrata extract for 8 weeks demonstrated significant improvement in their Visual Analog Scale (VAS), Japanese Knee Osteoarthritis Measure (JKOM), and their Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in comparison to placebo. Findings Here Curcuma spp. Roots of Curcuma are used as a spice commonly known as turmeric. Curcumin, a polyphenol extract of turmeric, is well known for its anti-inflammatory and antioxidant effects, and it has a long history of use in traditional Chinese and Ayurvedic medicine. Treatment with Curcuma has been found to strongly inhibit the production of inflammatory mediators. Researchers have demonstrated that human patients randomized to Curcuma domestica trails experienced significant improvement in Western Ontario and McMaster Universities Osteoarthritis Index scores in comparison to baseline over a 4-week period and less abdominal pain and discomfort compared to ibuprofen. Findings Here Another human trial demonstrated that curcumin had comparable efficacy, but better safety and fewer adverse effects than diclofenac. Findings Here Withania somnifera Withania somnifera (Ashwagandha) is an Ayurvedic medicine known for its anti-inflammatory and analgesic effects. Withania somnifera extract has been shown to slow the degradation of bovine Achilles tendon type I collagen by inhibiting the activity of collagenase. Treatment with W. somnifera has also decreased swelling, redness, deformity, and ankylosis in a collagen-induced arthritis rat model. It has been demonstrated that an aqueous extract of W. somnifera showed a significant chondroprotective effect on damaged human OA cartilage via diminishing the gelatinase activity of collagenases. In a 12-week human clinical trial, treatment with W. somnifera extract was associated with significant reductions in the mean WOMAC and Knee Swelling Index in comparison to baseline and placebo. A significant reduction in scores for pain, stiffness, and disability was also observed. Findings Here Ginger The anti-inflammatory activities of ginger have been widely investigated in patients as well as in vitro and in vivo models. Several clinical trials have been performed to assess the effects of ginger on OA pain-relief. Researchers have found that patients treated with ginger extract had lower VAS scores and gelling or regressive pain compared to placebo. Another study revealed that ginger extract was associated with reducing knee pain and WOMAC indices, although it was associated with gastrointestinal side effects. Further researchers have suggested that topical ginger extract significantly improved knee pain, stiffness, physical function, and patient global assessments following 12 weeks of knee OA treatment. What happens when we combine herbs and supplements? There is evidence of synergistic effects when different herbs are combined, including improvement in therapeutic outcomes and safety. Supplementation with boswellia combined with N-acetyl-D-glucosamine and ginger for 6 months, was found to significantly improve pain-free walking distance and WOMAC signs/symptoms for patients with moderate knee OA in comparison to standard OA management. Boswellic acid combined with methylsulfonymethane (MSM) has been found to improve knee OA pain management and functional recovery along
5 Wonderful Herbs for Dog Joint Care
It’s a sad realisation when we notice our dog getting a little stiffer or moving a little slower. Of course, we take it upon ourselves to make them as comfortable as possible. Joint degradation is a normal part of life, but as we know, certain things can speed it up. Alongside this, there are things we can do to potentially limit some of the damage, and food, nutrients and herbs that can help modulate the inflammatory process. We have compiled 5 of our favourite herbs for joint care in the dog. Joint Degradation Joint degradation is characterised by inadequate production of compounds necessary to its structure, along with reduced collagen synthesis. This can be a result of physical stress, trauma, autoimmunity, or aging. Here, inflammation is upregulated, creating further breakdown. It results in weak, damaged, or inflamed tissue with restricted or painful movement. Tissues are in the firing line when carrying out any physical activity and they may be susceptible to physical stress, strain, or trauma. Unexpected force or sudden changes in direction or speed are also more likely to cause issues (read: overweight dogs and those who chase balls regularly). This can be a particular risk during the winter, when walking in snowy, icy, or even muddy conditions. Tendons and ligaments are dependent on physical activity to develop, but it must be in moderation and appropriate. Joint degradation therefore has a number of risk factors: Nutritional insufficiency Physical stress or trauma Overuse – aging, Excess weight Autoimmunity The main concern in joint degradation is inflammation and the associated pain. And this is where our wonderful herbs can come in. 1) Horsetail Horsetail is a popular fern that has been used as an herbal remedy since the times of the Greek and Roman Empires. It grows wildly in Northern Europe and America, as well as in other moist places with temperate climates. It has a long, green, and densely branched stem that grows from spring to autumn. This plant contains a range of beneficial compounds, but we are most interested in its silica content and also its ability to function as an antioxidant. Silica, which is also present in bones, improves the formation, density, and consistency of bone and cartilage tissue by enhancing collagen synthesis and improving the absorption and use of calcium. Horsetail is rich in phenolic compounds which as we know are a group of antioxidants inhibiting oxidative damage. Not only this, but studies into rheumatoid arthritis have shown that horsetail has a down-regulatory effect on pro-inflammatory factors. It is often described as a great regulator of inflammation. Findings Here 2) Turmeric Turmeric is a flowering plant, but it’s the root we’re most interested in. Part of the ginger family, it looks very similar, but it’s the smell that helps you differentiate. Turmeric is frequently used in humans, to help with a range of diseases and conditions including skin, pulmonary, aches, pains, sprains, liver issues and cancer. Curcumin specifically is argued to be anti-inflammatory, antioxidant, anti-microbial, anti-tumour and helpful in wound healing. Used in Ayurvedic and Chinese Medicine for centuries, it is now finding a place in Western Medicine. Many joint issues feature chronic inflammation, and in supporting our dogs, we aim to reduce pain and inflammation. So here comes turmeric with its anti-inflammatory properties! Several studies have shown that when supplemented with turmeric, arthritic dogs show a marked improvement in their daily life activity without any side effects! Findings Here 3) Ginger A University of Miami study concluded that ginger extract could be a substitute to nonsteroidal anti-inflammatory drugs (NSAIDs). The study compared the effects of a highly concentrated ginger extract to placebo in 247 patients with osteoarthritis (OA) of the knee. The ginger reduced pain and stiffness in knee joints by 40 percent over the placebo. Research shows that ginger affects certain inflammatory processes at a cellular level, and as we know, many pathologies involving the joints have inflammation as the key player. There are more than 1300 types of ginger plant, and they contain a wide range of nutrients, including: vitamin C vitamin B6 the minerals magnesium, potassium, and copper gingerols, shogaols, paradols, and other phytonutrients and polyphenols Gingerol, shogaol, and paradols all have antioxidant properties, and gingerol and paradols are also anti-inflammatory. 4) Boswellia Serrata Boswellia resin can inhibit a branch of the arachidonic acid cascade related to leukotriene synthesis seemingly without affecting prostaglandin synthesis. It is considered that the excessive formation of leukotrienes is responsible for chronic inflammation. In 2004, researchers investigated the role of boswellia in inflammatory joint disease. After two weeks of treatment, an overall efficacy of the dietary supplement was evident in 71% of 24 eligible dogs. A statistically significant reduction of severity and resolution of typical clinical signs in individual animals, such as intermittent lameness, local pain and stiff gait, were reported after 6 weeks. Effects of external factors that aggravate lameness, such as “lameness when moving” and “lameness after a long rest” diminished gradually. They therefore concluded that boswellia herbal dietary supplement provided symptomatic support in canine osteoarthritic disease. Findings Here 5) Ashwagandha Ashwagandha is an evergreen shrub that grows in India, the Middle East, and parts of Africa. It has a long history of use in traditional medicine. We most commonly use it for its calming effect on anxiety symptoms along with building stress resilience, so it can help modulate any mood disturbances alongside chronic pain. But this wonderful herb may also act as a pain reliever, preventing signals from travelling along the central nervous system. It is also thought to have anti-inflammatory properties. One hundred and twenty-five patients with joint pain were screened at an Ayurvedic hospital in New Delhi, India. They ingested ashwagandha powder daily for three weeks to establish any symptomatic improvement. A significant change in post-treatment scores of tender joint counts, swollen joint counts, physician global assessment score, patient global assessment score, pain assessment score and patient self-assessed disability index score were reported. The researchers concluded that ashwagandha has a potential role
5 Superfoods for Joint Health in Dogs
This is one of the questions we are asked all the time here at My Pet Nutritionist. What foods can support joint health in my dog? Well, we thought we’d give you a rundown of 5 of our favourite. 1) Green Lipped Mussels GLM’s contains around 90 different fatty acids, glycosaminoglycans (chondroitin sulphate), glutamine (a glycosaminoglycan precursor), vitamins C and E and minerals including zinc, copper and selenium. The synergy of these nutritional components work in perfect harmony to support joint and mobility issues in pet. When looking at joint health you need to consider all mechanisms responsible for the disease and then how to address them. Inflammation It’s generally the inflammation and rubbing of joints that create pain and stiffness. The fatty acids in green lipped mussels with EPA (eicosapentaenoic acid) and DHA (docosahexanoic acid) are the most abundant. These are the important fatty acids that are known to reduce inflammation. GLM’s are natural COX inhibitors just like NSAIDS (non-steroidal anti-inflammatory drugs), so they can obtain the same pain free results without the negative side effects. They are also natural LOX inhibitors too. Degradation This is the main reason for the breakdown of the joint matrix. The joint matrix and connective tissue need to be supported by components that replicate the structure of joints, naturally. GLMs are rich in glycosaminoglycans and glycosaminoglycan precursors, known as GAGs. An important GAG found in GLMs is chondroitin sulfate a well-documented structural ingredient for joint support. Oxidation Free radical damage can create more degradation and inflammation so we need to support this with natural antioxidants found in GLM. Vitamin C and E are both abundant in GLM’s and essential for joint care. Joint Lubrication Synovial fluid within the joint matrix is incredibly important to support cushioning and movement. Alterations in synovial fluid (SF) lipid composition have been linked to both osteoarthritis (OA) and rheumatoid arthritis (RA). GLMs provide polysulfated glycosaminoglycans (PSGAGs), the building blocks for cartilage and joint fluid. 2) Turmeric Turmeric, Chew-Meric, Tum-eric, no matter how you say it (and yes, everyone seems to say it differently), it packs a whole lot of punch (good punch!) Turmeric is a flowering plant, but it’s the root we’re most interested in. Part of the ginger family, it looks very similar, but it’s the smell that helps you differentiate. When boiled, dried and ground, it’s the spice that is found in many Asian dishes. It has a warm, bitter, pepper like taste with a mustard-like aroma. It’s that spice that makes your hands yellow when you use it! And your worktops, sinks and utensils! It’s known as curcuma longer in the ginger family, and it’s the active compound curcumin that brings the benefits we speak of. It’s often named cure-cumin for the promise it brings. Turmeric is frequently used in humans, to help with a range of diseases and conditions including skin, pulmonary, aches, pains, sprains, liver issues and cancer. Curcumin specifically is argued to be anti-inflammatory, antioxidant, anti-microbial, anti-tumour and also helpful in wound healing. Used in Ayurvedic and Chinese Medicine for centuries, it is now finding a place in Western Medicine. Many joint issues feature chronic inflammation, and in supporting our dogs, we aim to reduce pain and inflammation. So here comes turmeric with its anti-inflammatory properties! Several studies have shown that when supplemented with turmeric, arthritic dogs show a marked improvement in their daily life activity without any side effects! Findings Here It seems to be down to turmeric’s ability to regulate cytokines. 3) Ginger A University of Miami study concluded that ginger extract could be a substitute to nonsteroidal anti-inflammatory drugs (NSAIDs). The study compared the effects of a highly concentrated ginger extract to placebo in 247 patients with osteoarthritis (OA) of the knee. The ginger reduced pain and stiffness in knee joints by 40 percent over the placebo. Research shows that ginger affects certain inflammatory processes at a cellular level, and as we know, many pathologies involving the joints have inflammation as the key player. There are more than 1300 types of ginger plant, and they contain a wide range of nutrients, including: vitamin C vitamin B6 the minerals magnesium, potassium, and copper gingerols, shogaols, paradols, and other phytonutrients and polyphenols Gingerol, shogaol, and paradols all have antioxidant properties, and gingerol and paradols are also anti-inflammatory. Antioxidants help the body get rid of free radicals, which can lead to cell damage and inflammation. Does My Dog Need Antioxidants 4) Oily Fish Joint degradation is characterised by inadequate production of compounds necessary to its structure, along with reduced collagen synthesis. This can be a result of physical stress, trauma, autoimmunity, or aging. Here, inflammation is upregulated, creating further breakdown. It results in weak, damaged, or inflamed tissue with restricted or painful movement. Essential fatty acids are well known to help modulate inflammatory responses found in cases of joint degradation. During the inflammatory response, certain enzymes catalyse the production of compounds which cause pain, redness, and heat. It has been discovered that omega-3 fatty acids inhibit these enzymes that result in this response. Great sources of omega-3 fatty acids include all those oily fish like sardines, salmon, and mackerel. Some plant based oils also contain omega 3 too, hemp seed oil has a great omega 6:3 ratio! 5) Bone Broth Bone broth is a liquid containing brewed bones and connective tissues. Bones themselves are rich in vitamins and nutrients, including calcium, magnesium, and phosphorous. In addition, brewing connective tissue into bone broth provides the body with natural compounds from the cartilage. You will also find collagen and cooking collagen turns it to gelatin, which provides the body with amino acids, which are the building blocks of proteins. It is not possible to say how much of any nutrient will be in a particular batch of bone broth, since this largely depends on the type and quantity of the bones and tissues that went into it, but a good rotation of bones and tissues will provide a range of nutrients.

Nutrients for Bone and Joint Health in Pets
There’s a difference between nutrients and foods – nutrients are what you find in foods. Whilst it can be a somewhat reductionist approach to health, if we know the role of certain nutrients, it can help us understand why we need to include them in our pet’s diet. In this blog, we thought we’d look at some of the most important nutrients for bone and joint health in pets. Bone is a light, yet strong connective tissue consisting of around 30% collagen and other matrix proteins with around 70% minerals. These minerals include calcium and phosphorus, but magnesium, sodium and potassium are also present in conjugated form. Bones come together to form joints. The type of joint formed determines the degree and direction of motion. For example, joints with a ball and socket formation allow for a rotation whilst hinge joints only allow for bending and straightening. In a joint, the ends of the bones are covered in cartilage, which helps reduce friction as joints move. With age, this cartilage can degrade. Tendons connect muscle to bone and are made up mostly of collagen. Ligaments surround joints and help to stabilise them. They also connect bone to bone. Bone Health Bone starts as a cartilage model which gets slowly replaced. Osteoblasts are the cells that form new bone; think of it as a blast that spreads, and osteoblasts spread to form new bone. Osteoblasts secrete osteoids which are simply unmineralized bone tissue. Soon after the osteoid is laid down, inorganic salts (calcium and phosphorus) are deposited which forms the hardened material that we know as bone. Inappropriate levels of calcium and phosphorus during growth therefore understandably contribute to bone deformities and skeletal disorders. Calcium Calcium is one of the most abundant minerals in the body. An optimal calcium intake is necessary for bone health at all stages of life. Dietary requirements for calcium are determined by the need for bone development and bone maintenance, which vary throughout life, being higher during puppyhood, adolescence, during pregnancy and lactation, and in the aging. When imbalanced levels of calcium are present, it can result in abnormal skeletal formation and/or function. Causes of Calcium Imbalance Vitamin D imbalance Kidney disease Liver disease Thyroid or parathyroid gland issues Diets rich in phytate and/or oxalate Primary hyperparathyroidism Cancer Certain medications Glucocorticoids promote calcium depletion High sodium diets – when sodium leaves the body it takes calcium along with it Sources of Calcium Raw meaty bones Sardines with bones Salmon Kale (cooked) Chia Seeds Bok Choi Egg Broccoli Liver Vitamin D Vitamin D is actually a hormone that promotes calcium absorption. In human health, you will have heard it referenced as the sunshine vitamin as it is produced in the skin in response to sunlight (UV) exposure. In studies of hip fractures in humans, there appears to be a seasonal variation; more occur during winter months and fracture patients often have low vitamin D status. When supplemented with Vitamin D and calcium, incidences of fractures often reduce. Findings Here https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1240026/ Vitamin D plays an indirect role in bone health by managing calcium levels in the body. It controls absorption of calcium in the intestine and the amount of calcium excreted by the kidneys. If Vitamin D levels are low, then the intestines struggle to absorb calcium. Calcium is key to bone mineralisation (hardening), without calcium, bones are unable to form correctly. Not only that, but due to the lack of circulating calcium, the body mobilises it from the bones by way of increased parathyroid hormone. This not only weakens the bones, but it also creates a new issue, namely secondary hyperparathyroidism. Vitamin D deficiency include symptoms like: Simultaneous deficiency/imbalance in calcium/phosphorus, Rickets (soft and weak bones in young dogs), Osteomalacia (soft and weak bones in adult dogs), Osteoporosis (weak bones leading to fractures), Neurological abnormalities, Hypocalcemia (low calcium levels), Elevated parathyroid hormone (symptoms include bone pain, depression, kidney stones, hypertension, cardiac arrhythmias, and kidney failure), Posterior paralysis, Ataxia (neurological issues including gait abnormality, difficulty walking, tremors), Quadriparesis (weakness in all four limbs). Food Sources of Vitamin D Flesh of fatty fish (salmon, tuna and mackerel) Fish Liver Oils Beef Liver Egg Yolks Joint Health Other than the skeleton, which provides a rigid structural framework for the body, there are other connective tissues that provide support. Where a degree of flexibility is required, cartilage is a rubberlike tissue that offers semi-flexible support for structures. The other function of cartilage is to prevent friction and enable smooth movement around joints. Cartilage is formed by chondrocytes which mainly consist of collagen and proteoglycans. Ligaments are made from tough, fibrous, dense connective tissue. They are made up of collagen, elastin, proteoglycans and a range of minerals including copper, manganese and calcium. Key to proteoglycan structure are the GAG’s chondroitin and dermatan sulphate. Tendons are very similar in structure and function as connectors that join muscle to bone. They are capable of carrying high tensile or compressive forces, facilitating movement around a joint. They have proportionally more collagen and less proteoglycan content as a result of the need for an even tougher structure. Joint degradation is characterised by inadequate GAG, proteoglycan and collagen synthesis to renew tissue in the face of degradation caused by physical stress, trauma, autoimmunity or ageing. Vitamin C Vitamin C is a water-soluble vitamin, antioxidant, and essential co-factor for collagen biosynthesis, carnitine and catecholamine metabolism, and dietary iron absorption. Whilst humans are unable to synthesize it themselves, dogs seemingly can in adequate amounts. Vitamin C is an essential for two enzymes required in collagen synthesis, so sufficient amounts are necessary for optimal joint (and bone) health in the canine. Sources of Vitamin C: Peppers Carrots Pumpkin Sweet Potatoes Seaweed Blueberries Glucosamine Glucosamine is a natural sugar that exists in the fluid around the joints, as well as in animal bones, bone marrow, shellfish, and fungi. The body uses glucosamine to build and repair cartilage. With age, cartilage can become less flexible and start to break down. This
Why Your Dog Needs Vitamin B6
You’ll have noticed that we talk a lot about vitamins and minerals here at My Pet Nutritionist. There’s a reason. For your pet’s body to do the jobs it needs to, it needs certain compounds, and that includes vitamins and minerals. Vitamin B6 is one of the B complex vitamins, it is water-soluble and necessary for a range of functions. Let’s take a look at it in a little more detail. Vitamin B6 Vitamin B6, also known as pyridoxine, is a water-soluble vitamin that the body needs for several functions. It’s significant to protein, fat and carbohydrate metabolism and the creation of red blood cells and neurotransmitters. Vitamin B6 cannot be made by the body and so it must come from the diet. Vitamin B6 and Behaviour The central nervous system runs on these chemical messengers called neurotransmitters. They are like the carrier pigeons of the body. Vitamin B6 is involved in the synthesis of a range of these neurotransmitters, specifically dopamine, serotonin and GABA. As we know, dopamine is involved in the reward circuitry in the brain, serotonin is known as the feel good neurotransmitter and GABA is like the brakes of the nervous system; it helps calm things down. So, if we are looking for balanced and appropriate responses to those things experienced by our dogs, they need access to sufficient levels of the right neurotransmitter. B6 will therefore play a role. In human studies we have linked vitamin B6 deficiency to depressive symptoms. Findings Here It is also linked to irritability. Findings Here A mild deficiency of B6 down-regulates GABA and serotonin synthesis, leading to the removal of inhibition of neural activity by GABA. Disordered sleep, irrational behaviour, and compromised cardiovascular function can result. In addition, a loss of hypothalamus-pituitary control and therefore aberrant hormone excretion. Vitamin B6 also has a direct effect on immune function and gene transcription/expression and plays a role in brain glucose regulation. Vitamin B6 and Brain Health Vitamin B6 is involved in managing homocysteine levels. In many cases, high homocysteine levels are associated with cognitive impairment and decline. Deficiency in B6 is regularly linked to high levels of homocysteine found in the blood; therefore posing a risk to brain health. Ensuring sufficient levels of B6 can therefore regulate homocysteine levels, and protect cognitive function. Findings Here Vitamin B6 and Eye Health High levels of homocysteine are also associated with age-related macular degeneration and so, B6 can therefore be beneficial in protecting eye health. As we know, B6 helps regulate levels of homocysteine in the body and in studies, when taking a regular dose of B6 supplementation, the risk of age-related macular degeneration decreased by 35-40%. This data was derived from human studies and so we must be careful when extrapolating to pets, but it certainly provides food for thought. In addition, other B complex vitamins were supplemented, so it would be pertinent to establish if the combination was of more benefit than single supplement. Findings Here Vitamin B6 and Arthritis The high levels of inflammation in the body that result from arthritis may lead to low levels of vitamin B6. There have also been studies demonstrating that vitamin B6 can help modulate pro-inflammatory responses in cases of arthritis. Findings Here The bottom line? If your dog is suffering with a chronic inflammatory condition, it would be pertinent to monitor their vitamin B6 status. Vitamin B6 and Anemia Due to its role in haemoglobin production, the most common sign of low B6 is anaemia. Haemoglobin is a protein that delivers oxygen to cells. When there is low haemoglobin, cells don’t get enough oxygen. The result is anemia. Signs and Symptoms of B6 Deficiency: Lethargy Abnormal heart rhythm Cracked lips Mouth ulcers Weakened immune function Inflammation of the skin Confusion/irritability Food Sources: Pork Poultry Fish Organ Meats Eggs As vitamin B6 is a water-soluble vitamin, it needs to be replenished daily in the body. Risk of Depletion: Hormone demands – if your dog is stress, they are at risk of depletion without sufficient supply Undernutrition Malabsorption (digestive compromise) Pyridoxine-inactivating medications (phenobarbital for example). Here at My Pet Nutritionist, we advocate a fresh food diet which is rich in a variety of vitamins and minerals. If your dog is suffering with a chronic condition, it may well affect their nutritional status, please check out our services if you would like to find out more. Thanks for reading, MPN Team
Why Does My Dog Need Minerals – Part Two
In our last blog we considered the importance of minerals for your dog’s health, but we only got so far. There are further minerals, ones we deem trace minerals, which are also important to optimal health. So, let’s get cracking. Chromium Within human realms, chromium is mostly talked about for its role in modulating blood glucose levels. It is considered that chromium acts as a cofactor that can enhance the effects of insulin on target tissues. In states of chromium deficiency, abnormal glucose utilisation results along with increased insulin demands. Findings Here Along with potentiating the action of insulin, chromium increases uptake of amino acids into muscle, heart, and liver and enhances protein synthesis. It also plays a role in regulating blood lipids. Increased Risk of Deficiency: Diets high in sugars and refined carbohydrates (results in increased urinary excretion of chromium) Increased stress (physical activity, infection, trauma or illness) Pregnancy Ageing Sources of Chromium: Broccoli Turkey Chicken Brewer’s Yeast Cobalt One of the things you may not have realised about Cobalt is that it is an integral part of Vitamin B12 (cobalamin – get it?). Why Your Dog Needs Vitamin B12 Cobalt is therefore essential for the function of cells. It is involved in the production of red blood cells and the production of antibacterial and antiviral compounds that prevent infections. This mineral plays a key role in the metabolism of fats and carbohydrates as well as the synthesis of proteins and conversion of folate in their active form. In the nervous system, cobalt also plays a role in the prevention of demyelination, which is a condition that results in damage to the membrane that covers the nerve fibres in the brain and spinal cord. This ensures efficient nerve transmission. Copper Copper has a number of functions throughout the body including: Energy production in mitochondria Mobilisation and transfer or iron from storage sites to the bone marrow Synthesis of collagen and elastin in connective tissue Acts as an antioxidant (as zinc/copper superoxide dismutase) Supports synthesis of melanin in the skin Synthesis of adrenaline and noradrenaline in the nervous system Breakdown of serotonin, histamine and dopamine Increased Risk of Deficiency: High intakes of supplemental iron, molybdenum, or zinc Prolonged use of proton pump inhibitors (acid reducers) Gastrointestinal disorders (chronic diarrhoea, inflammatory bowel disease) Increased levels of oxidative stress (air pollution, toxin exposure) Signs of Deficiency: Anaemia Increased vulnerability to oxidative damage Reduced immune responses Abnormal skeletal growth Changes and loss of hair and skin pigmentation Lethargy Excessive copper build-up in the liver can cause liver disease in some dogs. Common breeds of dog that are affected include Bedlington terriers, Labrador retrievers, and Dalmatians. There are clear genetic implications found in Bedlington Terriers which prevents normal copper excretion. Three forms of the disease occur: (i) asymptomatic – in which signs are yet to develop, (ii) acute -seen in dogs up to six years of age, with the sudden onset of severe illness shown as depression, anorexia (not eating) vomiting and possibly jaundice (yellowing of mucous membranes, whites of eyes and skin), and (iii) chronic – seen in middle-aged dogs with signs of chronic liver damage and sometimes failure which may show vomiting, weight loss, jaundice and abdominal swelling. It is considered that many commercial dog foods report total copper levels as higher than recommended, and some home-made diets may not furnish adequate amounts of copper. Findings Here That said, data indicates that copper absorption is greater when diets are animal protein rather than plant protein. Findings Here Iodine An essential mineral, iodine is used by the thyroid gland to make thyroid hormones that control many functions in the body including growth and development. If you would like to learn more about the thyroid gland and the conditions that often affect it, check out our blogs here: Hypothyroidism Hyperthyroidism Hyperthyroidism in Cats Iodine can only be obtained from diet or in supplemental form. Of interest, concurrent deficiencies in selenium, iron or vitamin A may exacerbate the effects of iodine deficiency. Seaweed like wakame are rich in iodine, but other sources include eggs and poultry. Iron Functions: Oxygen transport Oxygen storage as myoglobin Energy production Cofactor for multiple enzymes Production of neurotransmitters and thyroid hormone There are two sources of iron, haem, and non-haem. Haem is found primarily in meat and meat products where non-haem is found in plants. Haem is generally well-absorbed, whereas non-haem absorption is largely affected by other factors. Common inhibitors of iron absorption are phytates, tannins, starch, and proton pump inhibitors. The body has three unique mechanisms for maintaining iron balance and preventing deficiency and overload: Storage of iron Reutilisation of iron Regulation of iron absorption Iron from food is mainly absorbed in the duodenum. Iron can be in ferrous state (Fe2+) or ferric state (Fe3+). Fe3+ is not directly absorbed, but Fe2+ is easily absorbed. In the intestine, Fe3+ is converted by ferric reductases into Fe2+. When required by the body, iron is transported by transferrin to bone marrow and other tissues. Iron is required for the transport of oxygen, oxygen storage in muscle and is also a component of energy production. After absorption, any iron that isn’t needed, is stored as ferritin in the liver, spleen, or bone marrow. During times of high need, iron is then released. Most of the iron in the body is contained within red blood cells. Red blood cells have been noted to have a life span of around 110-120 days but when they reach the end of their life span, they release iron. The resultant liberated iron can be reused to produce new erythrocytes in bone marrow, stored as ferritin or released back into systemic circulation. Iron deficiency anaemia is the common condition associated with decreased iron levels, resulting in low circulating haemoglobin and reduced myoglobin. Iron deficiency is also associated with lower T and B lymphocyte, macrophage, and neutrophil function. Your Pet’s Immune System On the other side of the scale, iron toxicity is generally associated with supplementation. At a
Why Does My Dog Need Minerals – Part One
If you have been following any nutrition nerds (including us here at My Pet Nutritionist) then you will have likely come across the terms macro and micronutrients. We tend to reference them more commonly in the human realms, but that doesn’t mean that they don’t also apply to our canine companions (and feline for that matter). When we mention macronutrients we are referencing those needed in larger amounts in the body and they encompass protein, fat and carbohydrates. When we consider micronutrients we are looking at vitamins and minerals. Despite them being needed in micro amounts, they are still biologically necessary to all functions in the body. So, let’s take a look at minerals in a little more detail and see why your dog needs them. What is a Mineral? A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement. What on earth does this mean we hear you wonder? Well, let’s break it down. Minerals are naturally occurring, meaning they are not made by humans. They are inorganic, meaning they have never been alive. They are solid, meaning they are not liquid or gas. Each of them has a unique structure and arrangement which is how we know what they are. For the dog we are interested in 17 essential minerals. We have macrominerals which are needed in larger amounts and trace minerals which are needed in smaller amounts. Macrominerals Calcium You’ll likely be familiar with calcium as you were probably told to drink your milk so you would have strong teeth and bones. Calcium is the main structural component of skeleton and teeth, but it also plays a role in blood clotting. In addition, it is involved in the intracellular messaging triggering the contraction of muscle fibres. Calcium also plays a role in fat oxidation and it carries ATP (energy) with magnesium. There is an increased risk of deficiency in: Diets containing large quantities of phosphorus and sodium. Fat malabsorption (fat binds calcium, reducing absorption). Vitamin D deficiency. Diets containing large quantities of oxalates. Signs of Deficiency: Poor bone mineralisation, Muscle cramping and spasm, Increased irritability of nerve cells, Abnormal blood clotting and increased bleeding after trauma. Chloride Chloride is one of the most important electrolytes found in the blood. It plays a key role in controlling the amount of water and type of compounds that go in and out of cells. It therefore plays a crucial role in homeostasis. Chloride also contributes to muscle function and this includes the heart. This mineral helps red blood cells exchange oxygen and carbon dioxide too! Lastly, chloride supports digestive processes through its role in the production and release of hydrochloric acid in the stomach, and as we know, without this, foods won’t be properly digested and subsequently absorbed. Low levels of chloride are usually found alongside existing health issues which result in electrolyte imbalances. Sources of Chloride: Himalayan Salt Seaweed Magnesium Here at My Pet Nutritionist, we have a thing about Magnesium, for good reason. If you want to know more about this trusty mineral, then check out our full blog here: Why Is Magnesium So Important to Your Pet But the one often forgotten role of magnesium is the part it plays in energy, so we’ll do a recap. The bottom line is that insufficient micronutrient intake results in poor ATP production in the mitochondria. Remember that ATP is the currency of energy and the mitochondria is the powerplant of the cell, where it all happens. Magnesium and copper are star minerals for making ATP and without enough ATP or energy, the body hasn’t got enough resources to do what it needs to! In addition, a deficiency in magnesium can lead to mitochondrial damage. Signs and Symptoms of Deficiency: Muscle cramps and spasms Anorexia, nausea, vomiting Arrythmias Sodium and water retention Impaired action of vitamin D Increased Risk of Deficiency: Diets emphasizing processed foods and refined grains (largely nutrient deplete) Strenuous training Periods of rapid growth Intestinal malabsorption Medications (diuretics, steroids, laxatives) As a note, magnesium deficiency has also been linked to increased inflammatory cytokines, so this is a consideration to make in any chronic inflammatory condition. Findings Here Phosphorus Phosphorus in mainly used for the growth and repair of body tissues – it is a component part of bones, teeth, RNA and DNA. In the form of phospholipids, phosphorus is also a component of cell membrane structure and of the body’s key energy source, ATP. Many proteins and sugars in the body are phosphorylated. In addition, phosphorus plays key roles in regulation of gene transcription, activation of enzymes, maintenance of normal pH in extracellular fluid, and intracellular energy storage. A range of foods contain phosphorus, mainly in the form of phosphates and phosphate esters. Phosphorus in seeds for example, is in the form of phytic acid, the storage form of phosphorus. Because many species intestines lack the phytase enzyme, much phosphorus in this form is unavailable for absorption. Low phosphorus levels in the body can include anorexia, anaemia, proximal muscle weakness, skeletal effects (bone pain, rickets, and osteomalacia), increased infection risk, ataxia, and confusion. But in most cases, hypophosphatemia (low phosphorus) is caused by existing health conditions, such as hyperparathyroidism, kidney disorders, and diabetic ketoacidosis. In cases of chronic kidney disease, their ability to excrete phosphorus becomes compromised. This is why low phosphorus diets are often recommended. Kidney Disease Potassium Another electrolyte, potassium is also involved in energy production and membrane excitability and transport. Throughout the body there are a number of functions that are potassium dependent. If potassium is deficient, these enzymes or proteins are unable to carry out their job as they should. For example, one heat shock cognate protein, involved in protein folding, autophagy, apoptosis and cell stability requires potassium to carry out these functions. In a deficit, cell senescence results, along with DNA damage, carcinogenesis, and neurodegeneration. Findings Here The bottom line is that potassium helps nerves and muscles to function correctly, it maintains a
Top Tips to Help Your Dog Lose Weight
In 2017, 56% of dogs in the US were classed as being overweight or obese. This is a whopping 50.2 million dogs who are at risk of developing secondary conditions such as arthritis, certain cancers, kidney disease and an overall poorer quality of life with a reduced life expectancy. Yet in the same time frame, 58% of dog owners said they had tried to help their dog lose weight. The true obesity figures are hard to come by, but most practitioners that we speak with here at My Pet Nutritionist would say that obesity in pets is much higher. If we know that our pet is overweight and we are actively trying to help them lose weight, what’s going on? Most owners say it’s lack of time to exercise their dog, but exercise is just the tip of the iceberg when it comes to weight loss. So, we’ve put together our top tips for helping our pets lose weight. 1) Find out if your pet is overweight. A dog in its range of ideal weight for its breed should have an hourglass figure from above. You should be able to see a definite waistline. If you feel their body, the ribs should be palpable, but you shouldn’t be able to see them. During exercise, they will pant but they won’t be winded. They should be enthusiastic about movement. If you notice heavy panting, respiratory distress, general lethargy or reluctance to move along with what appears to be excess weight you really should be thinking about a dog diet (if other health issues have been ruled out of course). 2) Know the why! The long-term impact of pet obesity includes: Heat intolerance Diabetes Liver disease Osteoarthritis Poor immune function CancerReduced life expectancy Understanding that those extra pounds are seriously impacting our pet’s quality of life can help keep us on track. 3) Find out exactly what you’re feeding. Studies have consistently shown that when fed the same number of calories, those dogs fed a low carb, but higher protein diet lost more body weight than those dogs fed a high carb, low protein diet. Findings Here This is why we would always advocate a whole food, fresh diet that is moderate in protein and fat. If you’re not quite there with a fresh diet, studies have shown that pets fed on a canned diet as opposed to the equivalent dry, lose more fat. Findings Here 4) Monitor Intake! Any human who has tried to lose weight will remember being bombarded with information of what club to join or which diet to follow. None are quite as effective as keeping a food diary. This is key to your dog lose weight too! 2 meals a day, or even 1, what more is there to record? What about that crust off your sandwich, or the scraps the kids feed under the table? Or the treat the neighbour gives him every day? Once you start noticing and logging his food intake, you’ll be surprised at how many extra bits he gets! 5) Measure! It may sound simple, but the most important part of helping your dog to lose weight is to measure their food. Despite us doing it for years, feeding by eye can sometimes deceive us. It may seem a lot of work, but it really is the only way to ensure we are keeping tabs on what our pets are actually eating! 6) It’s all in the mind! Most owners struggle with dog weight loss plans because they feel guilty! Those sad eyes looking up at you when they think you haven’t given them enough! Dogs are scavengers. It’s this trait that domesticated them from the ancient wolf. Findings Here Some breeds, like the Labrador also don’t seem to have a satiety switch. They also learn through reinforcement – they have probably learned that if they look at you long enough, you’ll give in and offer them extras! Findings Here If you feel guilty when you leave the house for a few hours, save some of their daily intake for when you’re leaving. Do they always scrounge at the table when you’re eating, and you can’t say no? Put them in a different room whilst you’re eating or offer them a long-lasting chew (incorporated into their caloric intake). 7) Get by with a little help from my friends! You’ve been in that situation, trying to cut back on certain foods, then your colleague brings cake in! Minus the cake, it is often other well-meaning friends and relatives that can sabotage your dog’s weight loss plan too. You may be monitoring his calories, cutting back and watching everything that goes into his mouth, but if the children are still giving him scraps, the neighbours throwing treats over the fence and your Aunt feeding him sandwiches when she pops in to let him out, you’re on to a loser! Let everyone know your plan. Explain why you need to cut back and the risks associated with being over-weight. If they adore him enough to treat him, they’ll soon support your plan. If you don’t want to stop the treats, you could work out some calorie allowance by reducing some of his meal intake. Work out how many treats this is and put them in a jar on the tabletop. Let friends and family know that they can treat him from this jar. If it’s empty – he’s had his lot for the day! 8) Feed animals separately! Whilst the plan so far seems easy, as soon as you throw other pets into the mix it becomes more difficult. If they are fed in the same room, they can swap bowls and finish each other’s meals. If you have cats, you can bet your life the dog is eating the cat food too! Part of your dog weight plan needs to make provision for feeding animals separately. Summary It is generally thought that the single best way to shed unwanted weight is a calorie-controlled
