Turmeric: super spice or super overhyped? Jul 13, 2021

Show notes

Turmeric has been used in traditional Asian cultures for thousands of years as both a spice for cooking and for medicinal uses. Now medical science is backing up many of the traditional health claims made about turmeric and the compounds it contains. In this podcast, I investigate the turmeric story, outline why the focus seems to be on the bioactive compounds such as curcumin contained in it, what the research says about the many health conditions linked to it, and give you some guidance on the different supplemental forms available.

Is adrenal fatigue a thing? Jul 06, 2021

Show notes

Are you tired and worn out all the time? Are you always feeling tense and anxious? Do you crave salty foods? Then you could have adrenal fatigue. Well, that is to say, you could have it if it was actually recognised as a legitimate medical condition. In this podcast, I’ll explain what your adrenal glands do, look closer at the alternative health diagnosis of ‘adrenal fatigue’ and compare that to known medical conditions that do affect your adrenal glands.

Episode rewind: Protein supplements Jun 15, 2021

Show notes

The protein powder supplement market is big business. Popular in the world of sport where muscle growth is a priority, the marketplace is dominated by glossy pictures of cut models and an ever-expanding list of claims for how these products will pack on the muscle. So, do the bros at the gym have it right in that you need these supplements if you’re serious about the gainz, or could plain old boring ‘food’ do the same job? In today’s podcast, I dig deeper into the world of protein and muscle growth and explore what the research says about protein supplements and then put this into context for what it means for the typical sportsperson.

Episode rewind: Collagen supplements Jun 08, 2021

Show notes

Collagen supplements are big business. And is it any wonder when they are touted as the elixir for youthful and glowing skin. With plenty of A-list celebrities singing its praises, it’s no wonder collagen is having a moment in the spotlight. And a look at Google Trends shows search interest in collagen supplements really took off at the start of 2019 and it is showing no signs of slowing down. Reading the shopping list of health claims made about collagen - from turning back the clock on your skin, treating joint pain and even ‘healing your gut’ - you should rightly raise your sceptical flag. Yet when you look at the scientific evidence, there could just be some validity to some of these claims. That’s what I’ll be exploring in this podcast.

Are tart cherries the Holy Grail of exercise recovery supplements? Jun 01, 2021

Show notes

Tart cherries, also known as Montmorency cherries or sour cherries, are growing in popularity as a favourite sports supplement over the last couple of years. And here the interest is in their seeming ability to aid in recovery from intense exercise. In this podcast, I’ll look into what could make tart cherries different compared to other foods, the evidence for their benefits on exercise recovery and what other conditions they are being promoted for.

Sports drinks: a user’s guide May 25, 2021

Show notes

Keeping hydrated is important for optimal sports performance. And for decades we’ve had that area covered by sports drinks. But are sports drinks really performance-enhancing, or are they mostly marketing spin when just plain old water will do the trick for most people? That’s what I’ll explore in in my latest podcast along with giving you my personal DIY recipe for sports drink to get these drinks into you on the cheap.

Lactose intolerance: symptoms, diagnosis and treatments May 18, 2021

Show notes

Lactose intolerance is the most common food intolerance in the world. Rare in infants because they can easily digest lactose in breastmilk, its incidence skyrockets with age. And your genetic ethnic background is the key predictor of your risk of developing it. In this podcast, I’ll look at the causes, signs and symptoms of lactose intolerance and then go on to explain how it is diagnosed and importantly how it can be managed. And the good news is that rarely does that mean the exclusion of dairy products.

Nutrition for healthy ageing: fighting sarcopenia and inflammageing May 11, 2021

Show notes

With a rapidly ageing population worldwide, more adults than ever are becoming at risk of nutritional frailty. Older age is a time when specific nutrient needs may be higher while the ability to meet those needs has more barriers. In this podcast, I’ll highlight how our nutrition needs change as we age, the factors that make it harder to meet these needs, and the role that nutrition can play in promoting healthy ageing and improving the outlook of age-related diseases.
