If you are looking to lower your blood pressure you might want to add some tofu to your diet. According to a recent study, isoflavones — a compound found in foods like tofu, green tea, soy milk and peanuts — might help reduce blood pressure in young adults.
Researchers at Columbia University’s College of Physicians and Surgeons analyzed data from more than 4,000 participants in a study funded by the National Institutes of Health (NIH). They found that the study subjects who consumed the most isoflavones a day (more than 2.5 milligrams) had an average 5.5 mmHg lower systolic pressure (the top number of a blood pressure reading) than those who consumed less than 1.33 mg of isoflavones a day. According to the researchers, 100 grams of roasted soybeans have about 130 mg of isoflavones while an 8-ounce glass of soy milk has about 22 mg of isoflavones.
The investigators found that isoflavones might especially benefit African-American adults, who have a higher incidence of high blood pressure (hypertension)— about 42 percent of them are estimated to have it.
The authors of the study say these findings suggest that eating soy protein in combination with a diet high in fruits and vegetables, whole grains, and low-fat dairy could lead to as much as a 10 mmHg decrease in systolic blood pressure for people who are dangerously close to having high blood pressure, which could greatly improve their chances of avoiding hypertension.
