Do you have a sweet tooth? Chocolate can actually help you stay healthy and fight the effects of aging too. A study found that those who ate chocolate every day were 25% less likely to die of heart disease. These chocolate lovers also had a 23% lower risk of getting a stroke during the 11-year study period. Chocolates contain a compound known as flavonoids, which help maintain blood vessel function and can lower blood pressure too. Chocolate can be fat and sugary though, so moderation is key! Dark chocolate has the most flavonoids as well as the least amount of sugar content.
