Coffee

By and large, coffee seems to have an undeserved bad reputation when it comes to your health. Turns out, your morning cup o’ joe is a real brain-booster! In one promising study, researchers tracked nearly 700 healthy older men for ten years and found that those who averaged 3 cups of coffee per day experienced significantly less mental decline than nondrinkers did. Coffee drinkers may also be at lower risk for developing Alzheimer’s disease, type 2 diabetes, and certain cancers. The benefits don’t stop there — drinking a cup coffee within an hour of a workout can boost exercise endurance and performance. Turns out java lovers don’t need to feel one sip guilty about getting their morning fix.
