Vitamins are perishable substances. They are destroyed in a variety of ways. Some of them are destroyed by oxidation, some are destroyed by high temperatures, as in cooking, apparently some are destroyed by freezing, some are destroyed by light, some are affected by the presence of minerals, such as copper or iron. Some are thought not to be affected by any of the conditions to which food stuffs are subjected. The vitamin content of foods is often reduced by methods of storage, marketing and cooking. The full value of foods is obtained only by eating them in the fresh, raw state.

White flour, polished rice, degerminated corn meal, all denatured cereals, white sugar, jellies, jams, pasteurized milk and cream, refined syrups, sulphured fruits, and a whole long list of processed, refined and over-cooked foods that constitute a major part of present-day diet are devoid of vitamins as they are deficient in minerals.

What is the answer? This should be obvious enough. Eat more fresh, whole, raw fruits and vegetables and cease consuming the refined and denatured products. "Return to Nature" in your eating habits. Forsake the commercialized and spoiled foods that are fostered by the manufacturers of foodless foods.
