Dark Chocolate

Could chocolate’s mood-boosting effects be driven by more than just the luxurious taste and creamy melt-in-your-mouth texture? Some scientists think so. One study found that consuming a small daily dose of dark chocolate reduced stress hormones in individuals with high anxiety levels. To take full advantage of chocolate’s health perks, choose dark varieties that are at least 70 percent cocoa. And of course, try to keep portions in check since chocolate (even dark) is high in calories. One ounce daily (about 150 calories worth) is just the right amount to reap the tension-taming benefits without going overboard.
