Some foods are known to help lower blood pressure. Present study found that the protein in milk and soy can also help to lower systolic blood pressure.
A study reported in Circulation: Journal of the American Heart Association found that the protein contained in milk and soy-related value of systolic blood pressure lower.
"These studies suggest that foods or beverages high in protein such as milk and soy may help prevent and treat high blood pressure," study chief ujat Jiang He, MD, PhD, as quoted from ScienceDaily Tuesday 919/7/2011).
The trials conducted by researchers randomized controlled trial with results in milk and soy protein can lower blood pressure for people who have pre-hypertension and stage 1 high blood pressure.
The study found participants who consumed milk protein supplements have a systolic blood pressure of 2.4 mmHg lower, while those taking soy supplements proyein have systolic blood pressure of 2.0 mmHg lower.
Systolic blood pressure is the highest pressure in the blood pressure readings and pressure gauge when the heart contracts. Normal systolic blood pressure of less than 120 mm Hg.
In previous research has found that the decrease in systolic blood pressure by 2 mmHg can reduce at least 6 percent of deaths from stroke, and 3 percent of deaths from heart disease.
In addition previous studies have also found that eating lots of foods containing dairy products low in fat may help lower blood pressure. This is important, because high blood pressure is a silent killer that can cause heart attacks, strokes, kidney damage and other fatal events.
Looking at the influence that can be administered to decrease systolic blood pressure, then Jiang said further study is needed to make specific recommendations in terms of dietary changes.
