A small, pilot study has indicated that that a couple of servings of potatoes per day can lower blood pressure as much as oatmeal without causing weight gain.
A recent study conducted the by University of Scranton in Pennsylvania analysed 18 patients who ate six to eight small purple potatoes twice daily for a month. At the end of the study both their systolic and diastolic blood pressures (the top and bottom numbers on a blood pressure reading) dropped by 3.5 and 4.3 percent, respectively. The study was conducted by Joe Vinson, a professor of chemistry at the University.
Lona Sandon, a fellow professor at University of Texas Southwestern Medical Center at Dallas said “Potatoes are a pretty healthy staple food. They’re nutritionally low in fat, relatively low in calories, and are loaded with nutrition, particularly in the skin.”
