NAIROBI: Next time you have your fruits and vegetable serving, do so generously because science now supports that they could save you from high blood pressure. Scientists at Harvard Medical School found out that these classes of foods provide minerals such as potassium and substances called flavonoids, both of which are linked to lower blood pressure. The study found out that people who ate more whole fruits especially apples, pears, grapes, and raisins were less likely to develop high blood pressure compared to those who rarely ate those foods.
