6 Least Known Health Benefits Of Purple Potatoes

We are all familiar with the common white and sweet potatoes, which are consumed worldwide. However, there is a lesser-known variety that stands out for its vibrant color, versatility, and impressive nutritional profile—purple potatoes. Native to the Andes mountain region of South America, purple potatoes (Solanum tuberosum) belong to the Solanaceae family. Packed with health benefits, these unique potatoes deserve special attention, as we’ll explore in this article.

What Are Purple Potatoes?

Purple potatoes are part of the nightshade family, which also includes eggplants, peppers, and tomatoes. These potatoes are typically round with a striking blue-purple or black outer skin and rich purple flesh. When cooked, they have a nutty and earthy flavor.

The distinct purple color comes from anthocyanins, a type of antioxidant. Common varieties of purple potatoes include Congo, All Blue, Purple Majesty, Purple Peruvian, and Purple Fiesta.

Nutritional Profile of Purple Potatoes

Purple potatoes are an excellent source of dietary fiber, potassium, vitamin C, and B vitamins. They also contain antioxidants, with levels four times higher than those found in regular potatoes.

Health Benefits of Purple Potatoes

# Regulates Blood Pressure

Studies by the American Chemical Society suggest that purple potatoes may help reduce blood pressure due to chlorogenic acid, a phytochemical linked to blood pressure regulation.

# Reduces Oxidative Stress

Rich in anthocyanin polyphenols, purple potatoes protect cells from oxidative stress, which can lead to chronic inflammation, cancer, and male infertility. Research shows that consuming purple potatoes boosts the body's antioxidant levels.

# Prevents Blood Clots

A study in the Journal of Biochemical and Molecular Toxicology found that chlorogenic acid in purple potatoes can slow down blood clot formation, helping to prevent clots.

# Lowers Cancer Risk

Certain compounds in purple potatoes have been shown to help reduce the risk of cancers, such as breast and colon cancer. Research indicates that purple potato extracts can induce cancer cell death.

# Improves Digestive Health

The high fiber content in purple potatoes aids digestion by preventing constipation, cramping, and bloating. Fiber adds bulk to stools, allowing them to pass more easily through the intestines.

# Promotes Heart Health

Anthocyanins in purple potatoes are associated with a reduced risk of coronary heart disease and cardiovascular-related deaths, according to a study published in Advances in Nutrition.

Potential Risks of Purple Potatoes

Although purple potatoes have a lower glycemic index than regular potatoes, consuming them in large quantities can still impact blood sugar levels. People with diabetes should monitor their intake to avoid spikes in blood sugar.
