Studies show the ruby-red fruit may help reduce the buildup of plaque in arteries and lower blood pressure. Experts believe that pomegranate's benefits come from its powerful punch of polyphenols, including anthocyanins (found in blue, purple and deep-red foods) and tannins (also found in wine and tea). In a 2010 study ranking the antioxidant capacity of 3,100 foods from all over the world, pomegranate juice had the highest antioxidants of any fruit juice.
It's no secret that whole grains are a healthier choice than their overly processed, refined-grain cousins. A recent analysis of 45 studies found that eating at least three servings a day of whole grains was linked with a 22 percent lower risk of heart disease. That's because whole grains are rich in antioxidants, phytoestrogens and phytosterols—all nutrients that protect against heart disease.
