Treating hypertension (high blood pressure) can reduce the risk of a stroke by up to 40%, reports the World Health Organization.  High blood pressure (generally, 140/90 mm Hg or higher; however, anti-aging physicians aim for readings less than 120/80) is the most important risk factor for stroke. The US government's "Dietary Approaches to Stop Hypertension" (DASH) diet can help, providing menus low in salt and calories and high in nutrients.  Consume a variety of nuts, seeds, and beans, watch your intake of meats, poultry, and fish, and expand your repertoire of vegetables.  Go easy on processed foods, salty snacks, and cured meats.
