Michael Pollan’s recent book “In Defense Of Food“ has a seven-word by-line, but those words are a lesson for a lifetime:
Eat Food. Not Too Much. Mostly Plants.
That’s as simple as it’s ever going to be put, folks.
Eat Food: as in “real” food (basically, if it’s boxed, available as a tube or slice, or has 30 ingredients, it’s probably not “food”)
Not Too Much: No explanation required except to point out that if you really want to know when you have had enough so you can stop eating, then your meal-time has to be longer than about 20 minutes. You need to eat slowly enough that your stomach gets an opportunity to communicate to your brain that you have had enough.
Mostly Plants: No, all meat is not bad. But most of the meat you find in the grocery’s meat aisle is. Cows were not meant to be eaten after spending a lifetime of eating grain, slaughtered in factories and then ground and packaged in plastic. (And yogurt was never meant to be eaten in a pink tube either). Eat meat in moderation, but mix in plenty of the plant-varieties as well is the gist.
