Episode 6: Ultra-processed foods

We’ve apparently found the culprit for the obesity epidemic, and it’s “ultra-processed foods”. They’re the plastic-wrapped, industrially-produced foods with long lists of ingredients that apparently make up 60% of the average UK diet.In this episode of The Studies Show, Tom and Stuart tuck in to some “hyper-palatable” research on nutrition and health, discuss the main randomised trial in this area, and try (and immediately fail) to read out the whole definition of “ultra-processed foods” in one breath.The Studies Show is brought to you by the i, the UK’s best daily newspaper.
