Research reported in Duke University Health News shows that high potassium levels in raisins can help to lower blood pressure, but raisins can do more. They are high in the antioxidants that help protect body cells. They contain the mineral boron, which is associated with increased bone health and prevention of osteoporosis. Raisins are also rich in iron and copper, both of which are necessary in the formation of red blood cells. Raisins help correct iron deficiency anemia, and they promote blood clotting during wound healing. And other components in raisins protect vision. So let’s applaud raisins, nature’s candy.
