May improve your blood pressure

Purple potatoes may help with blood vessels and blood pressure wellness. This may be due in part to their increased potassium level, as this vitamin helps lower blood pressure, but their antioxidant concentration is also likely to have a role. In a modest four-week trial of adults with high blood pressure, eating six to eight purple potatoes twice a day decreased systolic and diastolic blood pressure (the top and bottom numbers of reading) by 3.5% and 4.3%, respectively. Furthermore, some research shows that consuming purple potatoes, as opposed to white potatoes, may lower vascular stiffness. Because your vessels can't expand as quickly in reaction to variations in blood pressure, having stiff arteries raises your chance of having a heart attack or stroke.

In general, consuming more polyphenol-rich foods, such as purple potatoes, which contain anthocyanins, may help relax and strengthen your blood vessels. In reality, the polyphenol chemicals found in purple potatoes and many other foods function to lower blood pressure in a manner similar to that of angiotensin-converting-enzyme (ACE) inhibitors, which are blood-pressure-lowering drugs.
