Why you should eat chocolate every day
A NEW study, by researchers at the University of the Incarnate Word Rosenberg School of Optometry in San Antonio, has discovered that eating a bar of dark chocolate can increase an adult's visual clarity.
Scientists came to this conclusion by testing the effects of dark chocolate on the vision of 30 healthy adults - nine men and 21 women - who were an average age of 26 years. None of the subjects had a history of eye disease.
In two separate sessions, the participants were required to eat either dark chocolate or milk chocolate - they then underwent a vision test two hours later.
The results of those who ate the dark chocolate revealed an improvement in visual contrast sensitivity (which is the ability to read small and large letters at different contrasts), when compared to the mik-chocolate eaters.
Subjects also experienced a slight improvement in clarity of vision after dark chocolate consumption.
Researchers were unable to identify why exactly this was the case but proposed the theory that "[...] an increase in retinal, visual pathway, and/or cerebral blood flow could be contributory, enhancing bioavailability of oxygen and nutrients to metabolically active sites."
"The findings reported suggest that a single dose of dark chocolate improves visibility of small, low-contrast targets within 2 hours compared with milk chocolate, but the duration of this difference and clinical relevance remains uncertain," the study's authors added.
The team believes more research is needed, but until then eat up - which is a fact is that dark chocolate is full of contains antioxidants called flavonoids, which can reduce inflammation, improve heart health and lead to better cognitive function.
