Article Synopsis
- Herbal remedies with phytoestrogens, like soy, were studied for their potential to lower prostate-specific antigen (PSA) levels in men, given their proposed role in prostate cancer treatment.
- During a study, 46 healthy men consumed soy protein daily for 3 to 4 weeks, with variations in dosage, while their PSA levels were monitored.
- The results showed no significant changes in PSA levels, despite soy reducing cholesterol and other heart disease risk factors, suggesting any benefits of soy on prostate cancer are not related to hormone changes.
Plant sterols, soy proteins, and viscous fibers are advised for cholesterol reduction but their combined effect has never been tested. We therefore assessed their combined effect on blood lipids in hyperlipidemic subjects who were already consuming a low-saturated fat, low-cholesterol diet before starting the study. The test (combination) diet was 1 month in duration and was very low in saturated fat and high in plant sterols (1 g/1,000 kcal), soy protein (23 g/1,000 kcal), and viscous fibers (9 g/1,000 kcal) obtained from foods available in supermarkets and health food stores.
