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.

Every child should be taught to cook in school, not just talk about nutrition all day. Good food can be made in 15 minutes. This could be the first generation where the kids teach the parents.

I profoundly believe that the power of food has a primal place in our homes that binds us to the best bits of life.

Homicide is 0.8% of deaths. Diet-related disease is over 60%. But no one talks about it.

I think authenticity is important whichever homeland you're from but one of the lovely things about British cooking is that we adopt great food and dishes from all of the lovely people who come from overseas to live in our country. We're a magpie nation - we take the best bits of other cuisines and embrace them as our own.

I never get tired of talking about food. I do getting tired of fighting governments when they are so clearly not putting the best interest of the children forward.

If Obama wanted to make radical changes to America's health long-term, all he has to do is treble the price of sugar and salt.
