Any kind of food you eat is going to have an impact on the world. If you switch to tofu and get off meat, the soy bean is doing enormous damage in the Amazon and all throughout South America.

I made the unexpected but happy discovery that the answer to several of the questions that most occupied me was in fact one and the same: Cook.

People say they don't have time to cook, yet in the last few years we have found an extra two hours a day for the internet.

Corn is an efficient way to get energy calories off the land and soybeans are an efficient way of getting protein off the land, so we've designed a food system that produces a lot of cheap corn and soybeans resulting in a lot of cheap fast food.

Is it just a coincidence that as the portion of our income spent on food has declined, spending on health care has soared? In 1960 Americans spent 17.5 percent of their income on food and 5.2 percent of national income on health care. Since then, those numbers have flipped: Spending on food has fallen to 9.9 percent, while spending on heath care has climbed to 16 percent of national income. I have to think that by spending a little more on healthier food we could reduce the amount we have to spend on heath care.
