Interest in collagen supplements continues to grow – and for good reason. That’s because despite rubbish claims that are way off the mark that there is ‘no evidence they work’ and ‘all the research is funded by the collagen industry’, the reality is very different. In past podcasts I’ve delved into the topic of hydrolysed collagen supplements and skin health and where there are now dozens of blinded randomised controlled trials showing a benefit in increasing skin moisture and elasticity and reducing wrinkles – with many of the studies free from any conflict of interest and all supported by plausible mechanisms as to why collagen, and not other protein sources, can do this. But for this podcast, I want to focus on one of the other reasons that people may take collagen: and that’s to give relief from joint pain and stiffness. So for this episode, I’m going to focus on arthritis and outline what the clinical evidence says and what unique biological mechanisms could be at play to support a unique effect of collagen supplements.

Irritable bowel syndrome is one of the most common gastrointestinal complaints. With no single identified trigger or treatment, IBS can be a minefield for a person to try and get on top of. Dietary changes like a low-FODMAP diet, supplements and stress modification all have a role to play. Another emerging treatment for IBS are probiotics. Probiotics may improve IBS symptoms by changing the gut microbiota and their metabolite production which can change gut motility, inflammation and gut hypersensitivity. In this podcast, I’ll look at the evidence for the use of probiotic supplements in IBS.

The establishment and development of the microbiome in the early stages of life can play a pivotal role in affecting our health throughout life. The formation of our microbiome happens during the perinatal period where it is influenced by the interaction between the microbiomes of mothers and infants. The microbial composition of breast milk plays an important part in this process. The microbiome of breast milk is also influenced by the gut microbiome of the mother through what is termed the gut-breast axis. In this podcast, I'll explore these mother-infant microbiome links and discover what the scientific evidence has to say about the potential for maternal probiotic supplements having a positive influence on the health of mother and infant.

Urinary tract infections (UTIs) are common with women about 30 times more likely to develop one than men. The bacterial infection of a UTI can cause painful burning sensations when urinating, frequent and strong urges to urinate, and changes in the composition of the urine. Antibiotics are the most common first-line treatment for UTIs, but there is growing interest in the role that nutrition-related treatments can play in reducing the risk of developing a UTI in the first place. Enter the most common self-prescribed and best-researched treatment: the humble cranberry. In this podcast, I’ll look at the evidence for cranberries in all their forms for helping to reduce the risk of developing UTIs.

Tendons play a vital part in helping us move. They are a collagen-infused super-strong bridge that connects muscles to bones allowing you to move your limbs. When overused, overloaded or damaged, these same tendons can cause us a lot of pain and movement impairment. Outside of the well-defined medical treatments and physiotherapy rehabilitation programs that assist with recovering from tendon injuries, there has been growing interest in the role of specialised tendon-targeted nutritional supplements in aiding repair and recovery. And for good reason, hydrolysed collagen is a key component of many of these supplements. In this podcast, I’ll look at where the evidence stands for nutritional supplements helping with tendon healing.

Do you want to lose weight, boost your metabolism, improve your digestion, detox your body, and have glowing skin all while keeping your body nicely alkalised and in balance? You can. All you need do is start each day with a glass of water with the juice of a freshly squeezed lemon in it. I mean water is good for you. And lemons, being a fruit, are good for you. So why not combine the two and get a quantum level of health-boosting synergy? Okay, so now for a dose of reality as I explore the whole lemon water trend and pull apart those amazing health claims to see what is hype and what is reality.

In recent years, there has been a surge of interest in the potential negative health effects of lectins. What are lectins? They’re a type of protein found in many plant foods such as legumes, wholegrains and some fruits and vegetables. If you take YouTube clips and popular diet books on their word, then these lectins are harmful to human health and are a major driver of inflammation, weight gain and many chronic diseases. Of course, to believe all this, you need to suspend the reality that humans have been eating these foods for thousands of years and it is only in modern times that we have been hit with all these major health problems. But hey, we need to blame it all on something I guess and lectins seem like a great way to sell books and get website clicks. In this podcast, I’ll explore the role of lectins in the diet, the alleged health risks, and counter that with the health benefits of eating lectin-containing foods.

It is something that all regular and not-so-regular exercisers have experienced: muscle pain and soreness in the days following a particularly hard training session. It is the price paid for the benefits exercise, especially resistance training, can have on growing muscle mass and strength, stability, glucose tolerance and bone density. The list of ways that people deal with exercise-induced muscle soreness is long, but in this podcast, I’ll explore one aspect. And that’s how protein helps with the recovery process and how it can be doing you good even if the aches and pains don’t feel any less.

Olive oil is a core staple in a Mediterranean-style diet. And it is for good reasons that it takes a central place as a ‘go to’ salad and cooking oil in kitchens around the world. In this age where too many foods are dubiously anointed with the title of ‘superfood’, extra virgin olive oil may just be one food deserving of this name in the oil category. In this podcast, I’ll look at the unique properties of olive oil and delve into what the scientific evidence says about its health benefits.

If you’re active on social media in the health and nutrition space, it’s very likely you’ve seen health advice over the last few years warning you about the evils of seed oils. These seed oils are toxic don’t you know? And they’re blamed for a whole host of health ills such as inflammation, lowered immunity, heart disease, type 2 diabetes, cancer and more. But the reality about seed oils is far less scary and there are few health concerns you need worry about. And likely quite a few health benefits to be gained by having them. In this podcast, I’ll look at what seed oils are, explain where all those health warnings have come from and put this all into context for what it means for your health and the foods you choose to eat.

Nightshades are a group of plants that belong to the Solanaceae family. They include some very commonly eaten foods such as tomatoes, peppers, eggplants and potatoes. These foods have been eaten for centuries by many cultures around the world and are considered a staple food in many traditional diets. Despite this, if you go digging into ‘health and wellness’ advice on the Internet, you’ll sometimes come across health warnings about nightshades. Digestive issues and inflammation feature prominently. In this podcast, I explore the evidence for any health harms arising from eating nightshades and put this into context for the many health benefits that they also provide.

From the common cold right through to the flu, it is something most people are faced with many times over in their life. And all of us could do with less coughing, sore throat, runny nose, body aches and fatigue in our lives. Our gut microbiota plays an important part in our immune system, so scientists for some years have looked at how changing our gut microbiota could influence respiratory tract infections. In this podcast, I’ll look at the current state of play for the role of supplemental probiotics, prebiotics and synbiotics in tackling acute respiratory tract infections.

What we eat is increasingly recognised as an important element in influencing fertility. With almost one in six couples experiencing fertility problems, knowing more about lifestyle factors such as diet that can alter this has major consequences. Most research in this area has focused on specific nutrients or food groups. But we don’t eat foods or nutrients - we eat whole diets which are described as dietary patterns. In this podcast episode, I profile new research into the area of dietary patterns and fertility to see what clues it can give to an optimal ‘fertility diet’.

Food porn is all about posting and engaging with photos of desirable and stylised food on social media. And those digital images can do real things to our brains. Researchers are now digging below the surface level of social media trends and are exploring how the sharing of food porn images can influence the food choices we make. In this podcast, I look at how that influence can help nudge us in the direction of better food choices.

Inflammatory bowel disease (IBD) is an umbrella term that describes chronic inflammatory disorders of the gastrointestinal tract. Crohn’s disease and ulcerative colitis are the two most common forms of IBD. In recent years, research into the role of diet in the cause and treatment of IBD has been gaining traction. In this podcast episode, I look at some of that evolving research into potential dietary triggers linked to causing IBD as well as possible treatments for managing IBD with diet.

For decades, carbohydrates have been at the centre of sports nutrition guidelines to help maximise physical performance and maintain muscle glycogen levels. But interest in an alternative approach, that being very low-carbohydrate ketogenic diets, has been growing for some time. With the dual aim of reducing body fat and enhancing the use of fat as a primary fuel source during exercise, there are plenty of glowing social media testimonials attesting to the benefits of this way of eating for athletes. But the research evidence for some years has been painting a very different, and often, opposing picture. And that’s what I explore in this podcast episode when I look at the findings of a recent systematic review on the topic of how the keto diet performs on exercise performance and body composition in athletes and trained individuals.

Age-related macular degeneration (AMD) is the leading cause of vision loss in people over the age of 50. AMD is a progressive disease seen as damage to the retina, which can lead to permanent central vision loss and even blindness. Good nutrition is important for eye health. And for many years, a range of nutrients have been specifically promoted as having a role in helping to protect the eye from AMD progression. Much of the evidence to support the role of nutrition in AMD has come from observational research. But there have been some long-term clinical trials using specific nutritional supplements that give a clue to what may work. In this podcast episode, I profile the results from a follow-up study to one of the biggest intervention studies in this area.

Eczema is a general term for rash-like skin conditions with atopic dermatitis being the most common form. Atopic dermatitis is a chronic inflammatory skin disease characterised by itching and recurrent eczema patches. Up to 20 percent of children can be affected by atopic dermatitis, but even in adults, it is far from uncommon with prevalence rates of between 1 and 3 percent. One growing area of study in the cause and treatment of atopic dermatitis is the role of the gut and skin microbiome through its effects on our immune system. One area of interest is the role of probiotics in treating eczema. And while much of the research here has been on infants and children, there has been a growing evidence base for adults as well. And that’s what I’ll be exploring in this podcast.

Advice to ‘eat the rainbow’ has been circulating in the nutrition sphere for some time. And no, it is not a call to action to get more Skittles in your life. Instead, it is all about choosing a variety of fruits and vegetables primarily based on their colour. Red, blue, orange, purple, yellow and green are the important colours here. And those colours occur because of the presence of a family of different polyphenol and other phytonutrient and other phytonutrients naturally found in foods. It is those coloured pigments that could explain many of the health benefits from eating these foods on your longevity, body weight, blood lipids and risk of chronic diseases such as type 2 diabetes and heart disease. In this podcast episode, I’ll explore the science behind ‘eating the rainbow’.
