Stop eating before you're full.

One of the problems is that the US government supports unhealthy food and does very little to support healthy food. I mean, we subsidize high fructose corn syrup. We subsidize hydrogenated corn oil. We do not subsidize organic food. We subsidize four crops that are the building blocks of fast food. And you also have to work on access. We have food deserts in our cities. We know that the distance you live from a supplier of fresh produce is one of the best predictors of your health.

Our ingenuity in feeding ourselves is prodigious, but at various points our technologies come into conflict with nature's ways of doing things, as when we seek to maximize efficiency by planting crops or raising animals in vast mono-cultures. This is something nature never does, always and for good reasons practicing diversity instead. A great many of the health and environmental problems created by our food system owe to our attempts to oversimplify nature's complexities, at both the growing and the eating ends of our food chain.

If it came from a plant, eat it; if it was made in a plant, don't.

Avoid food products containing ingredients that a third-grader cannot pronounce.

It's all very Italian (and decidedly un-American): to insist that doing the right thing is the most pleasurable thing, and that the act of consumption might be an act of addition rather than subtraction.

The other way that you democratize the food movement is through the public school system. If you can pay enough for the school lunch system so that it can actually be cooked and not just microwaved, so that these schools can buy local food, fresh food, because right now it's all frozen and processed, you will improve the health of the students, you will improve the health of the local economy, and you will have better performing students.
