Health Food - Way of Living

Food is a necessary for health. Proper food is fit for health. Every person has own choice. Some people like pizza. Some people like burger. Some people like ice cream. But you can't use pizza, burger and ice cream all the times all the time. You also need fruits, vegetables, and other kinds of foods. Water is also very important for your body. Food, anything eaten to satisfy appetite and to meet physiological needs for growth, to maintain all body processes, and to supply energy to maintain body temperature and activity. Because foods differ markedly in the amount of the nutrients they contain, they are classified on the basis of their composition and the source from which they are derived.

In the United States, interest in health foods and nutrition began to increase during the 1970s, accompanying the environmental and organic farming movements. Since then, the demand for organic and natural foods has grown along with concerns about the potentially harmful effects of chemical food additives and the nutritive value of highly processed foods. Health food industry is on a high

Organic foods are more correctly termed organically grown foods. Although worldwide standards vary, organic foods are generally produced without the use of irradiation, growth hormones, antibiotics, or synthetic fertilizers, herbicides, and pesticides. Organically grown foods are usually fertilized with manure and compost, and alternative methods are used to control pests and weeds. In the United States, concern about the labeling and certification of organic foods led to the 1990 Federal Organic Foods Production Act. In 2002 the National Organic Program was established to provide specific federal regulations governing the production, processing, and labeling of organic foods.

Research shows that organically grown food contains substantially higher levels of essential minerals when compared to conventionally grown health food. In addition, a study by the U.S. Department of Agriculture (USDA) indicates that the cultivation practices used in organic farming may have other long-term benefits, including topsoil preservation, improved water quality, and healthy populations of insects that control destructive pests.

Although no official definition exists for the term natural foods, it generally refers to foods that have been subjected to minimal processing and contain no artificial additives or ingredients. Nutritionists often refer to these as whole foods. Refined and processed foods usually contain fewer nutrients than whole foods. Refining whole wheat flour into white flour, for example, can remove more than half of the vitamins, minerals, and fiber. Common natural foods include wheat germ, raw sugar, sulfured molasses, whole grain bread without preservatives, and granola.

Dietary supplements contain ingredients that add nutrients to an individual's diet. They include a wide range of products, from vitamins and minerals to herbs, amino acids, and enzymes. Dietary supplements are taken by mouth in a variety of forms, including tablets, capsules, liquids, and powders.
