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

The invention includes a method of determining the effective density of nanomaterial agglomerates in liquids, such as but not limited to physiological fluids, using volumetric centrifugation. The method of the invention allows for the development of reliable and efficient in vitro dosimetry and methods for toxicological testing of engineered nanomaterials.
