One of the first attempts to quantify
dietary antioxidant needs of the body demonstrated that
consumption of certain berries and fruits such as blueberries,
mixed grape, and kiwifruit was associated with increased
ORAC plasma antioxidant capacity in the postprandial state
and consumption of an energy source of macronutrients
containing no antioxidants was associated with a decline
in plasma antioxidant capacity [33]. It was estimated that,
according to the energy intake of the diet, 5000–15000
