ABSTRACT:
BACKGROUND OF THE INVENTION
A. Field of the Invention.
This invention relates to the field of compositions for limiting the assimilation of dietary fat, and methods of making and using such compositions. More specifically, this invention relates to the field of compositions that inhibit dietary fat assimilation by physically entrapping the fat, and methods for making and using such compositions.
B. Description of Related Art.
People are becoming increasingly aware of the importance of limiting the ingestion and uptake of dietary fat. As a result, low fat foods are rapidly gaining in popularity. Such low fat foods are, however, only available for limited types of foods and are often less enjoyable to eat. Due to these deficiencies of low fat food, alternate means of reducing the amount of dietary fat have been tried.
One method of limiting the uptake of dietary fat is to consume dietary fibers which sequester the fat in a less-digestible form. A limitation of such dietary fibers is that they are ionically-charged, and they consequently sequester physiologically important nutrients and minerals such as phosphate. This sequestration limits the bioavailability of such nutrients and minerals.
SUMMARY OF THE INVENTION
There is a need for a dietary supplement which limits the assimilation of dietary fat without reducing the bioavailability of dietarily important nutrients and minerals. The present invention is based on the unexpected discovery that a surfactant in combination with non-digestible dietary fiber will limit the assimilation of dietary fat during digestion. The surfactant of the present composition is advantageously non-ionic (uncharged) and, therefore, disaggregates dietary fat without sequestering important nutrients and minerals. The disaggregated dietary fat can then combine with non-digestible dietary fiber to form a non-digested product which is subsequently eliminated. In a preferred embodiment of the invention, the composition further includes a food grade emulsifying agent.
It is an object of the invention to provide a dietary supplement which inhibits the assimilation of dietary fat. It is a feature of the invention that the dietary composition may be adapted to limit the assimilation of different types of dietary fats. It is an advantage that the invention may conveniently be taken before, during or after eating.
It is an object of the invention to provide a composition which limits the assimilation of dietary fat by physically entrapping the fat. It is a feature of the invention that the dietary composition does not significantly reduce the bioavailability of important nutrients and minerals. It is an advantage of the invention that the dietary supplement will not reduce the bioavailability of dietary phosphate.
It is an object of the invention to provide an oral dosage form of the dietary supplement which limits the assimilation of dietary fat during digestion. It is a feature of the invention that the dietary composition may be a separate oral dosage form, such as a tablet, capsule or powder. It is also a feature of the invention that the oral composition may be ingested with a meal to limit dietary fat assimilation. It is an advantage of the invention that the oral dosage form of the dietary composition may varied according to the desired use of the composition.
It is an object of the invention to provide a method for making an oral dietary composition which limits the assimilation of dietary fat. It is a feature of the invention that the method of making the dietary composition will include incorporating the composition as part of an oral dosage form such as a capsule, tablet or powder. It an advantage of the invention that the method of making the composition will include incorporating non-digestible dietary fibers.
These and other objects, features and advantages of the invention will be clear to a person of ordinary skill in the art upon reading this specification in light of the appended drawings.
