The health and natural foods industry has changed in the past decade from a few small stores selling primarily vitamins and other food supplements to larger stores selling various food products, health and beauty aids, books, and appliances. A few stores have even grown to supermarket size (over 10,000 sq. ft.). The growth of the health and natural foods industry has had an impact on the traditional food market as many supermarkets have added nutrition centers which stock health and natural food items. Though the industry is experiencing some difficulty with definitions of the terms natural and organic, it is possible that Federal regulatory policy would begin to alleviate misconceptions and definition problems.
