This branch of the Vedas was revealed thousands of years ago by Sri Bhagavan Danvantari, an incarnation of Krishna. Other instructions may seem less familiar, but they will bear themselves out if given the chance. We shouldn't be surprised to see bodily health discussed in spiritual writings. The Vedas consider the human body a divine gift, a chance for the imprisoned soul to escape from the cycle of birth and death. One who is temperate in his habits of eating, sleeping, working, and recreation can mitigate all material pains by practicing the yoga system.
Proper eating has a double importance.
Here are a few guidelines for good eating taken from the Ayur-veda and other scriptures. The most healthful are the foods of goodness. Such foods are sweet, juicy, fatty, and palatable. Foods that are too bitter, sour, salty, pungent, dry or hot, are of the quality of passion and cause distress. In other words, what you eat affects the quality of your life.
