Eating a particular kind of potatoes might improve blood pressure to an extent able to reduce the risk of heart disease. The findings come from an American study which analyzed the effects of purple potatoes in humans.
Purple potatoes (Purple Majesty) have been developed in recent years by crossing traditional varieties and are not genetically modified. Their distinctive color is due to the great amount of anthocyanins, antioxidants already well known for their healthy properties.

The study – published in the Journal of Agricultural and food chemistry- reveals that two small servings of this kind of vegetable is sufficient to reduce blood pressure by about 4 percent. And the good news is that no weight gain has been reported. Eighteen participants, most of whom were overweight with high blood pressure, were divided into two groups for 8 weeks. Participants of one group added purple potatoes to their diet, while the others did not use this food. Then groups have been switched in what is called a cross-over study.. Researchers checked systolic and diastolic pressure, body weight and other indicators. At the end of the intervention, eating a couple of helpings a day of purple potatoes turned out to have beneficial effects both on systolic and diastolic blood pressure values by reducing them of 3.5 percent and 4.3 percent respectively.
The research led by Joe Vinson and colleagues was somehow inspired by the fact that Americans use to have potatoes as the main source of vegetables. Purple-skinned potatoes are increasingly available in food stores.
