Dark chocolate contains certain antioxidants called polyphenols that could help fight chronic inflammation of tissues in the circulatory system. Moderate amounts of dark chocolate might also play a role in cancer prevention.
Yet another health benefit has been linked to eating chocolate: It may decrease your risk of stroke.
Many previous studies have linked eating chocolate with health benefits, including:
Chocolate consumption may lower blood pressure, help prevent formation of artery plaques and improve blood flow, according to other research.
Eating chocolate may even help with math, or at least counting.
Chocolate may also have anti-cancer benefits because flavonoids may help reduce the cell damage that can spur tumor growth.
Chocolate contains tryptophan, a chemical in the brain that is used to produce the neurotransmitter, serotonin. High levels of serotoninstimulate the secretion of endorphins, and produce feelings of elation. Serotonin is found in the antidepressant Prozac, and the designer drug “ecstasy” produces its effects by increasing serotonin levels in the brain.
