Purple potatoes, as well as pink, red and blue, contain anthocyanins, which are found in blueberries and which are due to their color.
If you haven't heard of purple potatoes , there are. Scientists from the University of Scranton, USA, claim that they are even particularly good for health. In a study, Dr. Joe Vinson, a professor of chemistry, found that eating purple potatoes resulted in a drop in blood pressure . Unlike our traditionally known root product, eating this does not lead to weight gain, but on the contrary.
For the purpose of science, 18 volunteers diversified their menu by including 6-8 potatoes a day for a month. After 30 days, it turns out that blood pressure values have dropped by 4 units, which according to scientists is due to the useful phytochemicals in them.
This is not the first study to show the power of potatoes for health. An article in the Journal of Nutrition earlier this year noted that consumers of red, purple and other pigments have lower levels of oxidative stress and inflammation - which are factors in the development of chronic diseases.
Purple potatoes are not a product of bioengineering science. They are a completely natural variety that we are not used to seeing on our table because of decades of cultivating crops for other purposes. Their color depends on the pigments in them.
According to Dr. Mary Ellen Kamaya, an expert in food and nutrient science at the University of Maine and a member of the Institute of Food Technology in the United States, flower varieties contain more antioxidants . In purple potatoes, as well as in pink, red and blue, there are anthocyanins - as well as in blueberries - which are due to their specific color.
Yellow potatoes are rich in carotenoids , which has a beneficial effect on the action of vitamin A in the body.
Although potatoes are sometimes a neglected food due to their high carbohydrate content , including them in moderation in the weekly menu can give us benefits.
