Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habits, because much of the food they eat, particularly processed foods, is not good for the health. Consequently, there has been a growing interest in natural foods. What are natural foods, you may ask? Well they are foods which do not contain chemical additives and which have not been affected by chemical fertilizers that are widely used in farming today.
    Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matters. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming areas.
    Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
