One of the best guides to food variety is colour. And for colour, there’s a group of natural plant chemicals called anthocyanins that are getting a lot of attention for their potential benefits on the brain. Anthocyanins are the pigments that give red, purple, and blue plants their rich colouring – they literally put the ‘blue’ into blueberries. A few years back on this podcast, I took you through the science of anthocyanins and brain health. In this episode, I’m revisiting that story with new research. In this episode, I’ll unpack what this new research review found, how it fits with what we already know about anthocyanins and the brain, and what it all means for your shopping basket and your long-term cognitive health.

If you’ve ever been stopped dead in your tracks during exercise by a muscle cramp, you know you’ll try almost anything to make it stop. There have been countless theories and remedies put forward to explain and treat a dreaded muscle cramp, but science still has a bit of catching up to do. But there is one particular treatment that has been gaining traction by athletes as a secret weapon to treat cramps. And it is one that sounds more like a pregnancy craving than a sports supplement: it is pickle juice. Is this just another passing fad, or is there actual science behind downing a shot of pickle brine to uncramp a muscle? In this podcast episode, I’ll cut through the noise to look at the evidence and the surprising mechanism of how it may work and spoiler alert: it has nothing to do with electrolytes.

Athletes are always on the lookout for a new sports supplement that could give them an edge. And there certainly are some sports supplements that deliver on their promises: creatine and caffeine are two clear examples. But a new supplement is starting to gain traction for its performance benefits: and that’s the humble mushroom. There's now emerging science suggesting that certain functional mushrooms, particularly the varieties of Cordyceps and reishi (also known as Ganoderma lucidum), may offer genuine benefits for endurance, recovery and immune function in athletes. In this podcast, I unpack the research behind these fungal supplements to see what's real, what's hype and whether these mushrooms deserve a spot in your supplement arsenal.
