Plant-Based ✅ and Brain Supplement ❌

Two things caught my eye this week on the nutrition front.

First — a piece from the University of Wollongong (https://www.uow.edu.au/the-stand/2026/five-mens-nutrition-essentials-that-matter-more-than-online-trends.php) cutting through all the online noise about men’s diet. One of the main takeaways was that plant-based diets can build muscle just as well as eating meat, as long as you’re getting enough protein. Which surprised me a bit.

Second, and this one’s a bit of a warning — a large study across 270,000 people (https://www.sciencedaily.com/releases/2026/06/260615025119.htm) found that high levels of tyrosine, which is in a load of popular brain supplements and nootropics, were consistently linked to shorter lifespans in men. Not what the marketing says.

It’s a good reminder that the supplement industry is very good at selling things that either don’t work or haven’t been properly tested long-term.

What’s your current approach to eating? Winging it, fairly structured, or somewhere in between? And is there anything nutrition-wise you’ve been meaning to sort out but keep putting off?
