Which compounds in purple potatoes are well-studied for accumulating in the retina to protect vision?
Answer
Anthocyanins
Anthocyanins, the pigments responsible for the striking color, are also noted for their specific benefits related to ocular health and vision maintenance. These beneficial pigments have been demonstrated in studies to possess the ability to accumulate within the structure of the retina. Once accumulated there, they serve a protective function by helping the eye tissue defend itself against damage caused by oxidative stress and excessive light exposure, providing a nutritional parallel to the benefits seen in other deep-colored fruits like blueberries.
