Schon mal gehört, dass Chitosan im Magen scharftkantig wird und die Schleimhaut verletzt ?
( Ernsthafte Frage ! )
Das halte ich für ein Gerücht (wahrscheinlich aus der Überlegung: halbe unzermahlene Krabbenpanzer drin?).

An investigation found that there is no valid scientific evidence to support claims that the ingestion of chitosan causes fat to be "trapped" or "bound" in the human G.I. tract, or that the use of chitosan-based dietary supplements causes any significant or noticeable weight loss results.

Sehe gerade, die Akte ist weg, aber dafür:

Chitosan manufacturer penalized. Natrol, Inc., and its president Elliott Balbert have agree to pay $250,000 to settle charges that they made false and misleading advertising claims for their chitosan-based weight loss products, some of which contained more lead than allowed by state law. Starting in 1998, they marketed Absorbitol Fat Binder, making claims that the chitosan ingredient in the product would cause the user to lose weight by absorbing fat and that it could bind "178% more fat than other brands" and 10.8 ml of fat "per gram of active ingredient." In 2001, it began marketing Chitosan 500 mg, Ultra Chitosan Fat Intercept, and Ultra Chitosan Fat Intercept Plus with similar claims. An investigation found that there is no valid scientific evidence to support claims that the ingestion of chitosan causes fat to be "trapped" or "bound" in the human G.I. tract, or that the use of chitosan-based dietary supplements causes any significant or noticeable weight loss results. The investigation also revealed that Chitosan 500 mg, Ultra Chitosan Fat Intercept and Ultra Chitosan Fat Intercept Plus contained lead in amounts that exceeded the 0.5 microgram daily limit allowed by Proposition 65. Under the stipulated judgment, the defendants must pay a fine of $220,000 and costs of $30,000. The judgment also prohibits them from making any unsubstantiated fat-binding or weight-loss claim about any chitosan-based product and requires them provide clear and conspicuous Proposition 65 warning for any chitosan-based product that would expose the user to more than 0.5 microgram of lead daily.
