From: "Jamie Oliver's Food Revolution"

The 2010 show, which was produced by English chef Jamie Oliver and Ryan Seacrest, follows Oliver as he attempts to reform the school lunch programs, help American society fight obesity and change their eating habits in order to live healthier and longer lives.

Premise:
Oliver, a celebrity chef and health campaigner in the UK, uses a grassroots campaign in the US to curb obesity. In the first season, his efforts are focused in Huntington, West Virginia, statistically one of the unhealthiest cities in the country.

In an early trailer for the show, Oliver challenges a group of first grade schoolchildren to identify fruits and vegetables, and they are unable to do so.
