5. Bittersweet chocolate
Bittersweet chocolate is distinct from sweet chocolate. The key difference is that it contains a high percentage of cocoa (50-90%). Remember that darker chocolate is better! This type of chocolate signals your brain to release endorphins, which assist in regulating stress and promoting emotions of happiness.
Cocoa also improves blood flow to the brain, which benefits the elderly by improving mental performance and helping them feel more balanced.
