Health food is a general term applied to all kinds of foods that are considered much healthful than the types of foods widely sold in supermarkets. For example, whole grains, dried beans and corn oil are health foods. A narrower classification of health food is natural food. This term is used to distinguish between types of the same food. Raw honey is a natural sweetener, whereas refined sugar is not. Fresh fruit is a natural food, but canned fruit, with sugars and other additives, is not. The most precise term of all and the narrowest classification within health foods is organic food, used to describe food that has been grown on a particular kind of farm. Fruits and vegetables that are grown in gardens that are treated only with organic fertilizers, that are not sprayed with poisonous insecticides, and that are not refined after harvest, are organic foods. Meats, fish, dairy and poultry products from animals that are fed only organically grown feed and that are not injected with hormones are organic foods.
In choosing the type of food you eat, then, you have basically two choices: inorganic, processed foods, or organic, unprocessed foods. A wise decision should include investigation of the allegations that processed foods contain chemicals, some of which are proven to be toxic, and that vitamin content is greatly reduced in processed foods.
Bread is typically used by health food advocated as an example of a processed food. First, the seeds from which the grain is grown are treated with bichloride of mercury, an extremely toxic poison. Later, the grain is sprayed with a number of very toxic insecticides and pesticides. After the grain has been made into flour, it is bleached with nitrogen trichloride or chlorine dioxide, both toxic. Next, a dough conditioner, usually ammonium chloride, is added along with a softener, polyoxyethylene. The conditioner and softener are poisons, and in fact, the softener has sickened and killed experimental animals.
A very toxic antioxidant is now added along with coal tar, a butter-like yellow dye. Finally calcium propionate, an anti-fungal compound, is added to keep the bread from getting moldy.
Other foods from the supermarket would show a similar pattern of processing and preserving. You see, we buy our food on the basis of smell, color, and texture, instead of vitamin content, and manufacturers give us what we want-even if it is poisonous.
The alternative? Eat health foods, preferably the organic variety.
