The purple anthocyanins act as scavengers of free radicals in the body and guard against acetaminophen toxicity as well.
Yet again, said purple pigments have been found to alleviate brain inflammation in rats and this may prove instrumental later on in the creation of therapeutic approaches to inflammatory brain diseases. And then again, in another study, rats on a controlled high-cholesterol diet and fed purple sweet potato flakes showed increased glutathione levels in the liver, leading the researchers to conclude that purple anthocyanins minimize oxidative damage to the liver caused by a high-cholesterol diet.
The purple variety of sweet potatoes isn’t the only one packed with goodness. Orange-fleshed sweet potatoes are touted for the potent vitamin A content as well, with one cup of this tuberous vegetable already capable of providing more than four times the RDA for this nutrient. In fact, orange sweet potatoes were utilized to solve the vitamin A and serum retinol deficiency in young children in Africa.
