Abstract: This invention relates to a method of treatment of patients having lesions resulting from cancer cells and to an application as an anti-cancer composition of undenatured whey protein concentrate.

Abstract: Undenatured whey protein concentrate is administered to HIV-seropositive individuals to elevate their blood mononuclear cells, glutathione (GSH) level, body weight and sense of well being. In addition T-helper cells concentration and their T-helper cells/T-suppressor cells ratio are slightly elevated.

Abstract: The present invention is concerned with a whey protein composition comprising a suitable concentration of whey protein concentrate wherein the whey protein concentrate contains proteins which are present in an essentially undenatured state and wherein the biological activity of the whey protein concentrate is dependent on the overall amino acid and small peptides pattern resulting from the contribution of all its protein components and a method of producing said whey protein composition. The invention also relates to several applications of said composition.
