After water, tea is the most popular drink in the world. We turn to it for comfort, for a break in the day, and increasingly, for its claimed mood‑calming powers. Scroll through social media and you’ll find no shortage of claims that tea, or more so one of its bioactive compounds called L‑theanine, are a natural answer to stress and anxiety. In this podcast episode, I take a closer look at those claims through the lens of a new review that pulled together clinical trials on green tea, its key bioactive compounds, and mood with a particular focus on L‑theanine and anxiety.

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.
