Eat food. Not too much. Mostly plants.
He then goes onto describe 4 rapid and far reaching changes in food culture and relationships (from soil to table) that have a profound effect on the western diet and therefore on health.
- From whole foods to refined-- the rise of white foods (refined flour and white rice); corn becomes corn syrup. These foods deliver glucose much more quickly and overwhelm the body's ability to produce insulin. Result-----> Type II diabetes
- From complexity to simplicity-- the rise of chemical fertilizers simplify the production of food, but decrease its nutritional quality. Four crops -- wheat, corn, soybeans, and rice -- account for 2/3 of the calories we eat (I find this astonishing).
- From leaves to seeds-- grains are easy to store, and easily and economically transformed into processed foods and animal protein. Replacing vegetables with grains means less nutrients, phytochemicals, fiber. The implications are barely understood.
- From food culture to food science-- science, journalism and marketing have replaced "mom" in determining what we eat.
- Eat food. Stay away from anything that your great-grandmother wouldn't recognize as food.
- Avoid food products that come bearing health claims. They are apt to be heavily processed. Bananas and yams may be silent, but that doesn't mean they don't have anything to do with your health.
- Avoid products with ingredients that are unrecognizable, unpronounceable, more than 5 in number, and/or includes high fructose corn syrup.
- Get out of the supermarket if you can. Farmer's markets sell food.
- Eat less and pay more. Good quality food costs more, but it is a good investment in your health, and the health of the planet.
- Eat mostly plants, especially leaves. Vegetarians and near vegetarians are healthier than carnivores. Plants are good for you!
- Eat more like the French, or the Italians, or the Greeks, or the Japanese. Adopt the principles of a food culture, not food science.
- Cook. Take part in the process of providing sustenance and communion. Escape the culture of cheap fast food.
- Eat like an omnivore. Add diversity to your diet.
