It's not the extremes and the treats that are the problem. It's the everyday.

Heads know that failing to invest in good, nutritious food is a false economy and parents won't tolerate reconstituted turkey being put back on the menu.

Many kids can tell you about drugs but do not know what celery or courgettes taste like.

I'm better with my hands, and I always loved the slightly romantic idea of starting with bits of wood and being able to create something to sit on, to eat from, to store your clothes in.

I wouldn't say that processed food, ready meals and even takeaways aren't relevant to modern life, it's just that over the past 40 years there are three generations of people who have come out of school and gone through their home life without ever being shown how to cook properly.

From quite an early age I realised the effect that good food can have on others.

I challenge you, to go to any school and open 50 lunchboxes, and I guarantee you there will be one or two cans of Red Bull, there'll be cold McDonald's and jam sandwiches with several cakes.
