According to the American Heart Association (AHA), eating higher amounts of a compound found in citrus fruits like oranges and grapefruit may lower ischemic stroke risk for women. Those who ate the highest amounts of citrus had a 19 percent lower risk of ischemic stroke than women who consumed the least.
According to the National Health and Nutrition Examination Survey (NHANES), fewer than 2 percent of US adults meet the daily 4700 mg recommendation and also of note, a high potassium intake is associated with a 20 percent decreased risk of dying from all causes. The fiber, potassium, vitamin C and choline content in oranges all support heart health.
An increase in potassium intake along with a decrease in sodium intake is the most important dietary change that a person can make to reduce their risk of cardiovascular disease, according to Dr. Mark Houston, an associate clinical professor of medicine at Vanderbilt Medical School and director of the Hypertension Institute at St. Thomas Hospital in Tennessee.
