I agree that peoples' attitudes twoard food come from their youth. Some people may have been turned off to veggies as children because the veggies were poorly cooked. If a little kid is getting veggies that had the life boiled out of them day in and day out, while getting yelled at to eat them, of course they'll protest.

Meat has more of a response to failure. People can get meat cooked to their liking ranging from rare to well done. No one wants a well done veggie.
