Eating raisins and soy appears to help ward off high blood pressure, according to two studies presented on Sunday, AFP reported.
Munching on a handful of raisins three times a day helped people with slightly elevated blood pressure lower their numbers after several weeks, said one of the studies.
Researchers think it may have to do with the high level of potassium in the shriveled, dried grapes.
A second study on soy showed that daily intake of foods like tofu, peanuts and green tea helped lower blood pressure in more than 5,100 white and African American people aged 18-30.
Soy and the isoflavones it contains work by boosting enzymes that create nitric oxide, which in turn helps to widen blood vessels and reduce blood pressure, a researcher explained.
