Taking on carbohydrates during exercise is a well-described way to help fuel muscle and endurance. But the research in this area took a decidedly strange turn some years ago when it was shown that the simple act of just swishing a carbohydrate-containing drink in your mouth for a few seconds can also have a performance advantage. This was research that I simply could not believe when I first came across it, but it has been replicated many times now. In this podcast, I’ll look at just how carbohydrate mouth rinsing can improve sports performance.

It was back in episode 55 that I first tackled the topic of collagen supplements. It proved to be one of my most popular episodes ever. And for good reason as there is a growing evidence base to support many of the health claims made about collagen: from improving skin health to perhaps even helping with sports injury recovery and osteoarthritis. In this podcast, I give an update on the growing scientific evidence for the use of collagen supplements. I’ll also explain how there is certainly a plausible biological mechanism to explain how this particular dietary protein source can have a targeted benefit even after digestion.

One of the best guides to food variety is colour. And for colour, it is a group of natural plant chemicals called anthocyanins that are getting a lot of attention for their beneficial effects on our brain. Anthocyanins are the pigments that give red, purple, and blue plants their rich colouring. They’re responsible for putting the ‘blue’ into blueberries and a bunch of other berries as well as some foods with bright red-orange colouration. In this podcast, I’ll look at the science behind how these anthocyanins can help keep your brain healthy and functioning well throughout life.

Weight loss supplements are big business. Fat burners, fat blockers, metabolism boosters, appetite suppressants – these are just some of the popular kinds of pills, potions and herbal concoctions that fly off pharmacy and health food store shelves. But how effective are any of these products? That’s what I’ll explore in this podcast.

Chromium is an essential trace mineral that is most closely tied to helping insulin work to lower glucose levels. That means you will often see it as a recommended supplement for people with diabetes. In this podcast, I’ll look closer at what chromium does in our body, where you find it in foods, and unpack the numerous health claims made about it in helping control blood sugars and even shed excess body weight.

Sugar addiction. Carb addiction. Junk food addiction. It seems we’re in the middle of a food addiction epidemic. But everyone is addicted to food to some degree; just try not eating for a day or two and you’ll crave the stuff. So, here it is a case of contrasting the deep physiologic survival need we have to eat versus the desire for specific types of foods. But can we really elevate what someone may consider a food addiction to that of a drug or gambling addiction? In this podcast, I’ll explore if food addiction really is a thing.

If there was a particular way of eating that could give you the best chance possible of keeping your mind healthy and sharp into older age, would you want to adopt it? Well there is, and it is called the MIND diet. Designed by medical researchers to help reduce the risk of dementia and loss of brain function as you age, the research base into it is growing. In this podcast, I’ll look closer at the evidence behind the MIND diet and give you all the key foods that are part of it.

You are what you eat. This is more than a trite phrase, as this mantra may have some direct relevance to the area of skin protection from UV sun damage. And here, it is the carotenoid family of vitamin A precursors which give many fruits and vegetables their vivid rich red, orange and yellow colours that could be getting into our skin to prevent the oxidative damage from the sun. In this podcast, I’ll look closer at those carotenoids and profile the latest research on how they could protect your skin. And as an extra reason for why you may want to eat more of these foods, I’ll explain why they could even help you get a date.

Going ‘all in’ on plant foods is a trend that is showing no signs of slowing down. But for those who are all about the muscle gainz for their sport and health, should you be concerned that your hard-won muscle growth is being compromised because you’ve embraced a mostly plant-based life? In this podcast, I’ll delve into the key differences between animal and plant-based proteins, the main supplements on the market for each, and profile the latest research on how people fare for muscle growth when weight training on a vegetarian versus an omnivore diet.
