How does the black chocolate affect the sight?

Consuming black chocolate with content of over 72 percent cacao increases blood circulation and significantly improves vision.

A study published by Rosenberg School of Optometic, U.S.A., shows that black chocolate improves vision to over 70 percent of people.

Black chocolate is rich in flavanol, an important antioxidant.

Inflammation is responsible for most degenerative changes related to chronic find, including heart disease, Alzheimer's and cancer.

Previous studies have suggested that flavanol also improves the flow of blood into the brain and cardiovascular system in the short term, but very few research has been done for its effects on human vision.

Black chocolate has eight times more flavanol than chocolate milk.

Two hours after eating chocolate, people who were part of the study were tested for multiple aspects of sight, including contrast, color perception, and effects of fade.

More than 70 percent of those in attendance improved in sight after eating black chocolate compared with those who had drunk chocolate milk.
