Methods for reducing at least one of the bioavailability and absorption of at least one of ingested fat, carbohydrates, and unwanted substances from foodstuff in a subject are disclosed. The methods described herein include administering an amount of a nanobiopolymer, or combinations of nanobiopolymers, sufficient to reduce at least one of the bioavailability and absorption of ingested fat, carbohydrates, and unwanted substances to a subject, such as a human subject.

Methods for reducing bioavailability and absorption of ingested substances

Method of preparing a keratin-based biomaterial is provided. The method comprises a) reacting keratin with a polymer having at least one of an amine and carboxylic functional group in the presence of a carbodiimide cross-linking agent to form a cross-linked keratin-polymer material; and b) freeze drying the cross-linked keratin-polymer material to form the keratin-based bio-material. A keratin-based biomaterial thus prepared is also provided.
