Chocolate is made from plants, which means it contains many of the health benefits of dark vegetables. These benefits are from flavonoids (known as Vitamin P), which act as antioxidants. Dark chocolate contains a large number of antioxidants (nearly 8 times the number found in strawberries). Flavonoids also help relax blood pressurethrough the production of nitric oxide, and balance certain hormones in the body. Chocolate contains phenyl ethylamine, a mild mood elevator. Cacao, the source of chocolate, contains antibacterial agents that fight tooth decay. However, chocolate with a high sugar content will negate this benefit. Dark chocolate contains significantly higher amounts of cacao and lower amounts of sugar than white chocolate, making it more healthful.
Now before you go out and satisfy your sweet tooth there are a few downsides.
