Blueberries
Blueberries may very well be the most potent age-defying food—they’re jam-packed with antioxidants. When researchers at Cornell University tested 25 fruits for these potent compounds, they found that tangy-sweet wild blueberries (which are smaller than their cultivated cousins) packed the most absorbable antioxidants. Research shows a diet rich in blueberries can help with memory loss, prevent urinary tract infections, and relieve eyestrain. Add up to 1/2 cup of blueberries to your diet a day for maximum health benefits, recommends Ronald Prior, PhD, adjunct professor of food science at the University of Arkansas in Fayetteville. This alone provides just about double the amount of antioxidants most Americans get in 1 day. (Enjoy your berries even more with these 11 tasty blueberry recipes.)
