Yes, they do have lessons about it all their school lives - that's my point. They don't need cooking lessons to reinforce that message. Healthy lifestyles has been a cross-curricular theme for years and, as I mentioned, we even had to teach it in foreign languages. If they've been taught even half-well, most secondary pupils could tell you how to say things like 'Fast-food is unhealthy, One should eat five portions of fruit and veg a day, One should not eat too much sugar' in whatever foreign language(s) they've been taught. I agree with you, bags, it's not a lack of education, but the typical school dinner of pasta with a gloopy sauce followed by an iced bun, which is damaging.
