Imagine a world where children were fed tasty and nutritious, real food at school from the age of 4 to 18. A world where every child was educated about how amazing food is, where it comes from, how it affects the body and how it can save their lives.

I hear loads of cynics saying that I'll never be able to change anything. They say that junk food marketing and the ready availability of fast food is just too powerful. But I'd say in response, screw you. I know that most people, if they're really honest, are fed up with the same old rubbish

I think food culture is always evolving, and there will constantly be people looking both forward and back. That's what makes it exciting.

Industry, economy, honesty and kindness form a quartet of virtue that will never be improved upon.

Now, everyone is excited about food - cooking, growing, learning - watching it on TV, buying books, trying things at home. It's the greatest time ever to be in food - which is why it's so hard to see so many people still relying on processed food. I am hoping that we had a generational blip - and that these young people will continue on and pass on their love of food and creativity to the next generation of kids.

I hate making TV documentaries.

As soon as I was old enough to peer over the worktops, I remember being fascinated by what went on in the kitchen. It just seemed such a cool place, everyone working together to make this lovely stuff and having a laugh doing it.
