Nutraceutical: Soy protein intake

Indication: Cholesterol levels in pre/postmenopausal women

Source: J Clin Nutr, November 2004;80(5):1391-1396.

Research: Scientists assessed dietary habits in a cohort comprised of 1033 pre- and postmenopausal women with widely differing soy intakes using a food frequency questionnaire. The cross sectional study incorporated subjects from the Oxford arm of the European Prospective Investigation into Cancer and Nutrition, and included 361 non-vegetarians, 570 vegetarians and 102 vegans. Anthropometric, medical and lifestyle data were collected, blood samples were drawn, and plasma total, low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol levels were measured.

Results: Soy protein intake was inversely associated with total and LDL cholesterol concentrations and with the ratio of total to HDL cholesterol, but not with HDL cholesterol concentrations. Mean plasma LDL cholesterol concentrations in women with a soy protein intake greater than or equal to 6 g/d was 12% lower than in women who consumed less than 0.5 g/d. The researchers concluded that moderate intakes of soyfoods as part of a regular diet are associated with favorable blood cholesterol concentrations.
