Most potatoes are rich in vitamin C, which is essential to grow and repair body tissues, support the immune system, and maintain cartilage, bones and teeth. Potassium, also high in potatoes, reduces high blood pressure, benefits the heart and kidneys, and tends to reduce the effects of anxiety and stress. Minimal research has been completed on the other vitamins and nutrients in potatoes.
This is why Aymeric Goyer, associate professor in the College of Agricultural Sciences at Oregon State University, studied the levels of vitamin B9, or folate, in different potatoes.
