"Our instincts give us a few clues about our nutritional needs, such as thirst, the hunger for salt, the pleasantness of sweet things, and the unpleasantness of certain odors or very acrid or bitter tastes.

But within the boundaries of cravings and disgust, habits and customs become the dominant forces in diet. "Professional dietitians" and other "experts" primarily function as enforcers of cultural prejudice." - Ray Peat on Vegetables, etc. - Who Defines food?
