PART II: What kind of Food Should I Eat?
RULE #29 - Eat like an omnivore.
Whether or not you eat any animal foods, it's a good idea to try to add some new species, and not just new foods, to your diet - that is, new kinds of plants, animals, and fungi. The dazzling diversity of food products on offer in the supermarket is deceptive, because so many of them are made from the same small handful of plant species, and most of those - the corn and soy and wheat - are seeds rather than leaves. The greater the diversity of species you eat, the more likely you are to cover all your nutritional bases.
"Eat food. Not too much. Mostly plants."
