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.
High-quality food is better for your health.
Fairness forces you - even when you're writing a piece highly critical of, say, genetically modified food, as I have done - to make sure you represent the other side as extensively and as accurately as you possibly can.
Every major food company now has an organic division. There's more capital going into organic agriculture than ever before.

In corn, I think I've found the key to the American food chain. If you look at a fast-food meal, a McDonald's meal, virtually all the carbon in it - and what we eat is mostly carbon - comes from corn.
Perhaps more than any other, the food industry is very sensitive to consumer demand.
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.
