How much greater is the antioxidant activity of blue/purple vs. white/yellow potatoes?
Answer
Two to three times greater
Blue and purple potato varieties possess significantly higher antioxidant activity compared to standard white or yellow potatoes. Specifically, due to the high concentration of anthocyanins, these colored tubers have been shown to offer two to three times the antioxidant activity when compared against white or yellow varieties. This difference in antioxidant capacity is directly linked to the protective benefits these compounds offer against cellular damage caused by oxidative stress.
