Send us a text In this episode we look at the results in Nature Medicine of the Zoe study and think about what might have made it a stronger paper and what questions are still not answered. We talk about an antibiotic cream that may prevent viral infections and finally a Nutri-sante cohort study that shows the potential dangers of emulsifiers, which are a very common ingredient in many of our common sports supplements.

Send us a text We run through a selection of interesting articles, all of which demonstrate key flaws that we keep seeing in nutrition research. Testing at the wrong time, wrong timeframe to followup for that testing, competing interests that blow the mind. Articles that demonstrate the researchers deeply held beliefs rather than take the science and understanding forward. Enjoy!

I then sit on the sidelines and enjoy the fighting between factions on the sides of the Ultra Processed Food safety/blame war and am very glad not to be in the line of fire and feel some empathy for those involved. We finish with some articles on weight loss with different carbohydrates, the impact of fibre on cancer risk and an older article on post menopausal...

A review through some interesting options for pre race optimisation such as coffee mouth rinsing, defecation, topical bicarbonate, some interesting new ideas to explore.

Then a nice microbiome paper that tells us why some mice seem to be lazier than others. Can we stretch this to human athletes? Also we ask where can we shoehorn in continuous glucose monitors - it looks fancy and must be useful for our patients....

Send us a text More on the discordance between what is healthy for us and what gets the best performance. If seems to be very good for our health, but performance improvements are mixed at best. Fructose added to our drinks is great for getting sugars in during a race, but terrible for our insulin sensitivity and triglyceride levels. Also will carb restriction thin our bones and a HIT study where they don't seem to get very out of breath. This podcast is a lighthearted review of the medical lite...

How are dieticians managing REDS on the ground - is everyone following the new guidelines or still managing as a female athlete triad but calling it REDS?

Also, how food intake cant be seen separately from sleep and a hunt for data on insect supplements. This podcast is a lighthearted review o...
