Chitin and Chitosan have a wide variety of uses in healthcare. Most important are wound care, implants, fat and cholesterol-binding drugs, and drug delivery. Fat Absorbent : The ability of the Chitosan molecule to scavenge fat and cholesterol in the digestive system, plucking it from the stomach and excreting it in the duodenum, has significant implications for its use as a beneficial food additive. Foods containing Chitosan or Chitosan complexed with a fatty acid could be designed to reduce obesity, cholesterol levels and the incidence of colon cancer.
