The “paleo” diet means eating foods that our Paleolithic (i.e. “stone age”) ancestors are thought to have eaten. This means a diet of fish, game, grass-fed meats, vegetables, fruit, roots, and nuts, and excludes grains, beans, dairy products, refined salt, refined sugar, and processed oils. This is basically a low-carb, all “natural” diet.
Although it is undoubtedly good to avoid high-salt, high-carb, high-sugar processed foods, it’s not clear that a strictly “paleo” diet is really necessary. Whole grains, for example, provide valuable calories, nutrients, and fiber. A “paleo” diet is probably much more healthy for you than a typical American diet, but you also probably don’t
need to be quite so strict. A simpler rule to follow comes from Michael Pollan: “Eat food. Not too much. Mostly plants.” That just means: stay away from processed foods of all types, go easy on meat, and eat plenty of fruits and vegetables. You can’t go wrong with that recipe!
