The truth about detox and other food myths
The one I really enjoyed looked at the food myth that annoys me the most: the "detox diet". They took two groups of young, urban party-type girls, and put one on a detox diet and the other on a normal diet for a week. Result, predictably, was that the detox diet had absolutely no effect, apart from making the detox group feel really awful.
Another complete waste of time is drinking two litres of water a day to improve your skin.
But it's not all about debunking unscientific nonsense. They also looked at some more evidence-based diet ideas, which include eating spinach to prevent or reverse macular degeneration, and eating tomatoes to protect against skin cancer. The trials proved their effectiveness.
Pretty good stuff! You can watch all the programmes on the website.
