The Truth About Food - Series 1 - How to be the Best

Series in which 500 volunteers and a team of celebrities discover how and why what we eat can change our lives. Ex-world-record hurdler Colin Jackson swaps his favourite diet for that of some vegetarian martial arts experts; tests whether the Omega 3 in oily fish can give stressful cabbies a less taxing day; and discovers if the firefighters of Montana are better placed to lick the flames on constant snacking or the traditional three meals a day.
