But that's the challenge -- to change the system more than it changes you.

I still think we have a long way to go on rebuilding a culture of cooking. Everyday simple cooking.

Very simply, we subsidize high-fructose corn syrup in this country, but not carrots. While the surgeon general is raising alarms over the epidemic of obesity, the president is signing farm bills designed to keep the river of cheap corn flowing, guaranteeing that the cheapest calories in the supermarket will continue to be the unhealthiest.

If you're not hungry enough to eat an apple, you're not hungry.

The issue of snacking is complicated. In principle, "grazing" is probably a good idea. It would even out the insulin spikes and things like that from eating large meals. The problem is it makes it harder for people to control the amount they're eating.

I think there's a real tension between capitalism and morality. That's not to say these systems aren't powerful and useful, but to assume that capitalism can somehow assure moral behavior or character, that's just a pipe dream.

When you go to the grocery store, you find that the cheapest calories are the ones that are going to make you the fattest - the added sugars and fats in processed foods.
