Soy May Lower Blood Pressure

A relatively small intake of soy protein may help reduce systolic blood pressure.

Individuals who consumed the most soy protein per day had lower systolic blood pressures than those who ate the least amounts, according to a new study. The top group consumed more than 2.5 mg per day of soy isoflavones. One cup of soy milk contains 22 mg of isoflavones, suggesting that soy consumption does not have to be very high to result in lower pressures. These isoflavones may increase production of nitric oxide which widens blood vessels and reduces blood pressure.
