Can you tell us what your current diet is? If it is not vegetarian, why not?

What's your guiltiest pleasure, and how do you rationalize it?

Kirsten Hagfors

KETCHUM, IDAHO

I like French fries, and I probably shouldn't eat them very often. I actually came up with a rule: Eat all the junk food you want as long as you cook it yourself. One reason we struggle with obesity today is that special-occasion foods like French fries, cakes and cookies have become so easy to obtain.

Do you think organic farming can be done on a large scale, bringing cost down closer to that of nonorganic foods?

Michael Lawrence, NASHVILLE

I think organic food will come down in price. But we need to pay people a living wage so they can afford to buy real food. In the 1970s, the rise of fast food paralleled the collapse of family wages. In a way, cheap food has subsidized that collapse. We have to rebuild those two.

Can small changes in American shopping and eating patterns make a difference collectively?

GRAND RAPIDS, MICH.

How can consumers ensure a strong food system for future generations?

MEMPHIS, TENN.

Are genetically modified crops harming our health?
