Natural Food as Choice of Healthy Diet
Increasingly, over the past ten years, peopleespecially young peoplehave become aware of the need to change their eating habits, because of the food they eat, particularly processed foods, is not good for health. Consequently, there has been a interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers widely used in farming today.
Natural foods, for example, are vegetables, fruit and grain have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it essential vitamins and minerals. This in itself is a natural process with the use of chemicals and fertilizers, the main purpose of which is to increase the amount but not the of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move 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 rubbish. Chickens kept in this way are not only as food; but also produce eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing from experts on diet. Take, for example, the question of sugar. This is actually a nonessential food! a natural alternative, such as honey, can be used to sweeten food if this necessary, we can in fact do it. It is not that sugar is harmful in itself. But it does seem to be additive: the quantity we use has grown steadily over the last centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is to provide us with energy, in the of calories. There are no vitamins in it, no minerals and no fiber.
