The relationship between food and mood has been studied for over 5000 years. When someone eats a steak they might behave pretty rudely for instance. In several studies done in prisons, vegetarian food was supposed to have reduce the violent tendencies in inmates. The Bhagavad Gita has almost an entire chapter dedicated to studying the effects of type of food on mood, consciousness, behavior, and culture. Foods in modes of goodness like milk, sugar, fruits, vegetables are described making a person calm, contended, and peaceful. Foods in the mode of passion such as excessive hot or cold, spicy and tartaric foods (tamarind) generate excitement and a sense of needing to achieve something like name, fame honor, etc. Foods in the mode of ignorance such as meat, fish, eggs, mushroom, alcohol, highly fermented foods cause a person to be lazy and dull and also callous to spiritual needs.

In addition he can provides mantras and spiritual processes to counteract the influences of past Karma and planetary forces on the soul.
