Snack on Dark Chocolate
In addition to its other documented health benefits, dark chocolate may help sharpen the mind. When participants in a study conducted at Northumbria University, in England, were given a drink containing high levels of cocoa flavanols, they performed significantly better on a math task than they did after having a placebo drink. Why? Researchers say that it’s possible that flavanols help improve blood flow to the brain. Even better, science has found evidence for what you suspected all along: Chocolate may help take the edge off stress. When Swiss researchers asked stressed-out people to eat 1.4 ounces of dark chocolate each day (they probably didn’t need much coaxing), the researchers found that after two weeks, the subjects had lower levels of the stress hormones cortisol and catecholamines.
