Jamie Oliver is a very famous chef for many reasons. His recipes are easy to cook and he also has spoken out about child obesity on TED.

He made many points when talking on TED about child obesity. One of his examples to back him up was that he went into a young class in a Primary School, brought in different vegetables and asked the young children what each of them was. The children had an extreme lack of knowledge about vegetables and didn't know what a lot of them were even called. This shows that children need to be taught about healthy food to get them into good eating habits when they're getting older.
