Just that really. I see so many kids having regular lunch/dinners that's barely contains any nutrition not out of laziness/budget but due to lack of education.
I can't think where I use any science knowledge gained from school in day to day life yet I had an hour a day once a week for years. Cooking on the other hand I had one term a year for three years. I think we had to make shortbread, a fruit salad and a flapjack. In the second year we had to make a tomato and cheese sauce. In the third I think we had to cook chicken breasts and something to do with beef. Yet I can still label parts of a cell, atoms and know some basics of the periodic table.
We literally use nutrition various times a day- why isn't it compulsory?
