1. Chocolate Helps You Relax Reach for a Hershey bar when you’re stressed? There’s a biological reason for that. Studies have shown that chocolate contains the compound anandamide that activates the same brain receptors as marijuana. No wonder a bite brings on bliss.5. Chocolate May Help You Live Longer A study in the British Medical Journal found that candy consumption can help you live longer—almost a full year longer!—than those who abstain from the sweet stuff. Participants who ate candy one to three times a month had the lowest mortality rates of the group, and researches postulate this may be due to the antioxidants in chocolate. A 2009 study also found that heart attack survivors who ate chocolate were less likely to die than those who went without. Stick to a one-ounce serving to get your fix without wrecking your waistline.
