Gas means overeating, or waterlogging with too much fluid intake. Navy beans, peas, sweet potatoes, apples, and other foods cause gas. Apples and other fresh fruits cause gas in those who are starch-poisoned. The habit is built by much water drinking between meals. Constipation is built by gas distention and too large fluid intake, forcing the kidneys to do the eliminating for the bowels. The present universal habit of water drinking to overcome constipation is another medical fallacy.
The tired feeling of a morning means food poisoning--toxemia. The physician should know the influence of food taken in excess, the influence of wrong combinations, and the influence of all mental and physical habits; then he can prescribe intelligently.
