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.

It was my second ever podcast episode released way back in February of 2020, but it has proven to be the most popular. It was titled The User’s Guide to Intermittent Fasting. Now, it is time to revisit the topic of intermittent fasting with an update on the clinical evidence for how fasting stacks up for its effects on body weight and metabolic health compared to other ways of eating. And that’s what I’ll be exploring in this episode by profiling the results of a recent review on this topic.

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’.
