A composition is provided comprising a plant sterol and a soy protein material and/or and isoflavone selected from genistein, daidzein, glycitein, biochanin A, formononetin, and their naturally occurring glycosides, where the plant sterol comprises at least 0.49% of the composition, by weight. The present invention is also a method for decreasing the blood concentration of total and LDL cholesterol in a human in which the plant sterol and a soy protein material and/or an isoflavone are co-administered to the human, where the plant sterol comprises at least 0.49%, by weight, of the combined weight of the plant sterol and the soy protein material and/or the isoflavone. Also provided is also a method for preventing or minimizing the development of atherosclerosis in a human in which a plant sterol and a soy protein material and/or an isoflavone are co-administered to the human, where the plant sterol comprises at least 0.49%, by weight, of the combined weight of the plant sterol and the soy protein material and/or the isoflavone. A preferred method involves co-administering to a human a plant sterol and a soy protein material containing at least 49% by weight soy protein and containing the isoflavone glycoside, glycitin. The plant sterol is at least 0.49% by combined weight of the co-administered plant sterol and soy protein material. The plant sterol can be B-sitosterol, campesterol, stigmasterol, sitostanol, or campestanol. Also an isoflavone can be administered in combination with the plant sterol and soy protein material. This isoflavone can be genistein, daidzein, glycitein, biochanin A, formononetin, and their naturally occurring glycosides and glycoside conjugates.
