The invention relates to the use of specific protein and/or peptide fractions having a high aspartate content for regulating plasma glucose concentrations and increasing insulin sensitivity in a mammal. The invention relates to a complete food fortified with aspartate equivalents as well as a supplement rich in aspartate equivalents that is given simultaneously with or even minutes up to an hour prior to the consumption of a meal comprising glucose. The nutritional or pharmaceutical composition contains at least one protein having a high aspartate content, preferably of soy or dairy origin, which is further enriched with aspartate equivalents from another protein and/or free aspartate equivalents. The protein fraction comprises glutamate equivalents in a weight ratio of aspartate equivalents to glutamate equivalents (asp:glu) between 0.41:1 and 5:1.

Compositions that provide sustained energy up to 8 hours with an amount of caffeine that is less than 25 mg are described. The compositions comprise at least an astragaloside compound, a ginsenoside compound, a stilbenoid compound, and caffeine. Many of the compositions further comprise an amino acid having anabolic properties (e.g., having a role in the regulation of protein metabolism), including one or more of the group of arginine, ornithine, citrulline, glutamine, and a precursor, analog, prodrug, and/or derivative thereof, as well as molecules that interact with arginosuccinate synthase and/or arginosuccinate lyase, and analogs, prodrugs and derivatives thereof. Methods of utilizing the described compositions include administering orally to a subject an effective amount of the described composition, such that the composition provides sustained energy for up to 8 hours with an amount of caffeine in the composition administered orally that is less than 25 mg.

A composition has ornithine, aspartic acid and vitamin B6, and it is used in preparation of hypolipidemic drugs, health-care products, foods or food additives.

It has been found that high amounts of aspartate equivalents in combination with vitamin B12 and/or biotin, especially in relative absence of glutamate equivalents, improve the metabolism of ketobodies and/or lactate in a mammal's body, especially in diseased or traumatic conditions. As a result, levels of ketobodies and lactate can be decreased and unphysicologically high acidity normalised. Thus, it is an object of the invention to provide an enteral nutritional or a pharmaceutical composition for the treatment and/or prevention of disturbed ketone and lactate metabolism, i.e. elevated concentrations of ketone bodies, lactate and/or other organic acids and/or insufficient pH homeostasis, especially elevated concentrations of ketone bodies and/or lactate, in a mammal's blood, wherein the composition comprises high amounts of aspartate equivalents in combination with vitamin B12 and/or biotin, preferably in relative absence of glutamate equivalents.
