Purple Potatoes Health Benefits That Will Surprise You

Purple potatoes, just like most members of the potato family, are native in the Andes mountains of South America. These purple potatoes stand out for their almost black or blue-purple outer skin and inner flesh that is colored brilliant purple, which does not change color even after being cooked.

There are many varieties of this vegetable available such as purple fiesta, purple majesty, purple peruvian, all blue and adirondack blue. The purple potatoes have a dense and earthy texture compared to the white potatoes. Furthermore, the starch content in purple potatoes is a cause for concern since it could increase the risk of diabetes, heart problems and obesity. However, if consumed in moderation, it’s a colorful yet healthy additive to the diet since it is full of other nutrients.

A hundred grams of the purple potatoes served along with its skin includes 18 percent of the required daily intake (RDI) of vitamin B6, 14 percent of the RDI of vitamin C, 21 percent of the RDI of copper and 8 percent of the RDI of potassium. Here are some of the other main health benefits derived from eating a serving of purple potatoes along with your food. 


The purple color content indicates the presence of high antioxidants, particularly polyphenol antioxidants called anthocyanins. The same antioxidants are present in blueberries too. Anthocyanin consumption is associated with lowering cholesterol and reducing heart disease and cancer risk. Similar to white and yellow potatoes, the purple varieties contain carotenoid compounds, caffeic acid, scopolin, chlorogenic acid and ferulic acid. 


The antioxidants in potatoes prevent cancers, especially colon and breast cancers. A study showed that cancer cells did not grow quickly when purple potato extract was consumed. However, more research needs to be done on the subject since the studies so far have been limited to lab rats and nothing has been tested on human beings. 

Blood Sugar

Compared to other potatoes, purple potatoes have lower glycemic index, thus causing lower risk of blood sugar spurts. The polyphenol compounds contained in the starch prevent the absorption of blood by the intestines. A study conducted on rats who were fed the purple potato extracts saw increased glucose tolerance levels and positive impact on maintaining normal blood sugar levels. 

Blood Pressure

Due to the amount of potassium derived upon eating purple potatoes, which are rich in polyphenol compounds, the blood pressure decreases when consumed. It is said to have a similar function to medication meant to lower blood pressure.
