Some of us enjoy a good fatty meal from time to time! We have always worried about the dietary intake of fat from this type of food. Chitosan is found in the exoskeletons of crustaceans. It is processed by removing the shells from shellfish such as shrimp, lobster, and crabs. The shells are then ground into a pulverous powder.
This powder is then stripped of specific chemical groups which allows the compound to actively "soak up fats." Basically stated, chitosan is a special fiber which is able to "soak up" or absorb anywhere from six to ten times its weight in fat and oils.
However, Chitosan is able to significantly bind with fat molecules and convert them into a form which the human body does not absorb. It prevents the absorption and storage of fat by converting into a gel which "traps" the fat. In some sort, it creates a "grease ball" from this excess fat, which is too large to be absorbed by the body. It then becomes an inert substance and gets passed through the body.
