问题     Health food is a general term applied to all kinds of foods that are considered more 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 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 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 infected 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.
