Adequate intake of soy foods may have a positive effect on plasma concentrations of homocysteine in premenopausal women.

Elevated serum levels of homocysteine have been established as a risk factor that promote the development of cardiovascular disease. The aim of this study was to examine whether consistent consumption of soy foods could alter plasma concentrations of homocysteine in premenopausal women. Researchers assessed the soy food intake of 201 Japanese premenopausal women and estimated their blood levels of homocysteine.

Researchers observed that a significant drop in serum concentrations of homocysteine appeared to be related with frequent ingestion of soy foods. Data from this study show that regular intake of soy foods may be beneficial in reducing the amounts of homocysteine floating in the blood of premenopausal women.
