2) Dark Chocolate is Good for Your Brain
Dark chocolate increases blood flow to the brain as well as to the heart, so it can help improve cognitive function. Dark chocolate also helps reduce your risk of stroke.
Dark chocolate also contains several chemical compounds that have a positive effect on your mood and cognitive health. Chocolate contains phenylethylamine (PEA), the same chemical your brain creates when you feel like you're falling in love. PEA encourages your brain to release endorphins, so eating dark chocolate will make you feel happier.
Dark chocolate also contains caffeine, a mild stimulant. However, dark chocolatecontains much less caffeine than coffee. A 1.5 ounce bar of dark chocolate contains 27 mg of caffeine, compared to the 200 mg found in an eight ounce cup of coffee.
