A New Isolated Soy Protein with High Levels of Nondenaturated Protein Shows Twice the Cholesterol-Lowering Effect of a Commercial Isolated Soy Protein

Soy protein has repeatedly proven effective for lowering plasma cholesterol levels. The mechanism of cholesterol reduction has not been conclusively clarified but 1 hypothesis implies an important role for the 7S soy globulin, the major water-soluble peptide fraction of unprocessed soy flour.

Summary:Soy protein has repeatedly proven effective for lowering plasma cholesterol levels. The mechanism of cholesterol reduction has not been conclusively clarified but 1 hypothesis implies an important role for the 7S soy globulin, the major water-soluble peptide fraction of unprocessed soy flour. This randomized placebo-controlled double-blind study evaluated the lipid-lowering effects of a new isolated soy protein product with the protein structure kept in the native, nondenaturated form compared with a commercially available soy protein supplement.
