Uncooked food is an integral component of human nutrition, and is a necessary precondition for an intact immune system. Its therapeutic effect is complex, and a variety of influences of raw food and its constituents on the immune system have been documented. Such effects include antibiotic, antiallergic, tumor-protective, immunomodulatory, and anti-inflammatory actions. In view of this, uncooked food can be seen as a useful adjunct to drugs in the treatment of allergic, rheumatic and infectious diseases.
