12. Dark Chocolate
A new study from Denmark found that those who eat dark chocolate consume 15 percent fewer calories at their next meal and are less interested in fatty, salty, and sugary foods. And research shows that dark chocolate can improve heart health, lower blood pressure, reduce LDL (“bad”) cholesterol, decrease the risk of blood clots, and increase blood flow to the brain. Dark chocolate boosts serotonin and endorphin levels, which is associated with improved mood and greater concentration; it’s rich in B vitamins and magnesium, which are noted cognitive boosters; it contains small amounts of caffeine, which helps with short-term concentration; and it contains theobromine, a stimulant that delivers a different kind of buzz, sans the jitters.
