I don’t believe in superfoods. Besides, capes don’t taste very good.
I believe in food. While it should be obvious what food is, it isn’t.
Food is fruits and vegetables, fish, meat, milk, cheese, eggs, grains. The closer those things are to how they came out of the ground or out of the creature, the more food-ish they are. (Yes, removing the dirt and sometimes cooking things are good ideas.)
Beware the boxes. Beware the not-found-in-nature colors. Beware the super salted, the super sugared, and the trans-fatted vampires.
Eat enough, but not too much. Enjoy what you eat. You’ll feel better.
