According to Dr. Wassertheil-Smoller if you are rich with potassium in your diet, their risk of stroke will become so slim especially to those people who are having post-menopausal. Potassium can lower blood pressure. Vegetables and Fresh fruits is a good source of Potassium. With 90, 000 post-menopausal women, Dr. Wassertheil and his team were able to determine who among them has a big chance of stroke and who has the slim chance through their incidence. And they found out that those women who are enriched with potassium didn’t undergo of stroke incidents. In fact they reduced their general risk of stroke by at least 12 percent. But you have to be aware that having potassium diet should be start at least before the onset of high blood pressure, because potassium could not help in either way when you are already having a high blood pressure. So when to start having a potassium diet, I guess we have to start now since the postmenopausal would start from 50 to 79.
