What specific phytonutrients are responsible for the vibrant color found in purple and blue potato varieties?
Answer
Anthocyanins
The striking, vibrant color present in varieties such as purple and blue potatoes is attributed to naturally occurring pigments known as anthocyanins. These compounds are powerful phytonutrients that function as antioxidants within the body, offering demonstrated protective effects in various studies. Anthocyanins are structurally related to the compounds responsible for the rich colors found in other familiar foods, specifically mentioning blueberries and blackberries. Integrating these colored tubers into a diet allows for an easy diversification of antioxidant intake, providing a broader spectrum of protective plant compounds when paired with standard vegetable consumption.
