Food and Thought is a book written by Dr. Manthena Satyanarayana Raju on Naturopathy. 'Health is Wealth'. Man's health is based on his food habits. He should also have a natural life style. So man can be called perfectly healthy only if he follows natural food and natural behaviour. A wise man requires a natural life style. But the modern man is devoid of peace since unnatural behaviour and unnatural food have cropped up into his life style.
