Contrary to widespread belief, shifting to a soy-rich diet alone may not be responsible for lower blood pressure among older women, a new study reveals.
Researchers at Baylor College of Medicine in Houston conducted the study on 24 menopausal women who had moderately elevated blood pressure. The women were randomly divided into two groups with the first group being given 80 mg of soy isoflavones while the second group was given placebo pills every day.
At the end of six weeks, the researchers tested the blood pressure of both the groups and found that there was no marked improvement in the blood pressure levels of those who had taken the soy supplements.
Lead researcher William Wong said that they stopped the study after six weeks since they doubted whether there were any long term effects. "If we didn't see anything in six weeks, we doubt there would be effects (longer term). I think that if people are looking for a magic bullet against high blood pressure, this is not it", he said.
