When thinking about health, sometimes we can turn to very old scriptures for inspiration and understanding.
Chapter 17 of the Bhagavad Gita breifly talks about three types of food:
17.08 The foods that promote longevity, vitue, strength, health, happiness and joy are juicy, smoother, substantial, and nutritious. Such foods are liked by persons in the mode of goodess. 17.09 People in the mode of passion like foods that are very bitter, sour, salty, hot, pungent, dry and burning; and cause pain, grief and disease. 17.10 People in the mode of ignorance like foods that are stale, tasteless, putrid, rottten, refuse, and impure. (like meat)
It makes a lot of sense to think that nutrious and juicy smooth foods promote better health and happiness that some of the others, whereas food that is starting to rot is bad for the mind and the body.
