A team of researchers from the Rosenberg School of Optometry at the University of the Incarnate Word in San Antonio, Texas found a new addition on the list of dark chocolate benefits. Apart from its great contributions to heart health and memory, the treat seems to be great for the eyes as well. Eating a bar of dark chocolate seems to improve one’s vision.
Dark chocolate seems to enhance vision clarity
For the study, researchers selected 30 adults that had never suffered any eye disease or vision trouble. The group consisted of 21 women and 9 men with an average age of 26 years. They split them in two groups and gave them differed types of chocolate. The first one had to consume a bar of dark chocolate, while the second one ate milk chocolate. Two hours after the meal, researchers had them undergo some vision tests.
This is how they noticed an advantage for those who ate dark chocolate. One of the tests had them read letters of alternate sizes colored in contrastive hues. The dark assortment of chocolate seemed to improve their contrast sensitivity, as they could read these mixed letters a lot better than those who ate milk chocolate.
A better oxygen flow in the brain might boost our vision
Also, dark chocolate boosted their vision even more. Their overall clarity got significantly better after they ate the healthier version of the treat. This was extremely interesting to observe, but researchers couldn’t tell for sure why this happened. However, they could make some suppositions.
Eating dark chocolate enhanced the blood flow in the brain, which might contribute to a better vision and retinal performance. Whenever this happens, more areas of the brain get access to nutrients and oxygen, which greatly improves their function. However, researchers couldn’t tell how much the effect of the treat lasts.
Before establishing a clear connection between dark chocolate and boosted vision, researchers need a lot more studies to prove it. Consuming the treat has many other health benefits anyway, so make sure you include it on your grocery list next time you go shopping.
