Dietary Therapy Chinese diet TCM believes foods boost your entire system with concentrated energy provided by a carefully selected combination of herbs. This is referred to as "medicinal diet" because many of the herbs are given as tasty dishes. It is not uncommon for the Chinese to treat a minor ailment with a specially prepared meal, or by including a particular ingredient in a dish. Such functional foods are especially popular in Chinese households where the knowledge of certain foods as medicine has been passed down through the generations. The understanding of foods to treat certain health conditions is as useful as keeping a fully-stocked medicine cabinet. Even though modern medicine has been available since the beginning of this century, people still prefer to use functional foods, either as supplement to drugs, or as an alternative course of treatment. If a person suffers from a chronic disease or metabolic disorder, and drugs or herbal formulae are not the best options, functional foods become an important method of treatment. The foods not only provide the nutrients that the body needs, but also cure or relieve the problem via their therapeutic actions.
