The researchers set out to see which of several interventions would improve cholesterol levels the most. In this study, 352 participants with a total cholesterol level less than 240 mg/dl were randomly assigned to supplement daily, for eight weeks, with 40 grams of either soy protein (providing 84 mg per day of soy isoflavones), milk protein, or complex carbohydrates from wheat.
Results showed that participants who took the soy protein supplement experienced a small but statistically significant 3.97 mg/dl decrease in total cholesterol and a 1.54 mg/dl increase in HDL ("good") cholesterol compared with people who took the milk protein or complex carbohydrates.
"There is increasing evidence that consumption of soy protein in place of animal protein lowers blood cholesterol levels and may provide other cardiovascular benefits," said author MR Wofford and colleagues from the University of Mississippi Medical Center, Jackson, MS.
