Don’t mix ‘em
Italian scientists have found that combining blueberries with cow’s milk destroys the antioxidant benefits they offer. Volunteers ate 200g of blueberries with 200 ml of either water or whole milk. Eating blueberries with water increased blood levels of antioxidants, combining them with milk did not. Previous work has shown that milk can interfere with the antioxidants in both tea and chocolate. This may result from milk proteins binding to the antioxidants. It may be time to rethink how we combine our foods.
