Can dark chocolate improve our eyesight? 25 Jul, 2018
Chocolate lovers rejoice!
Recent research by the University of the Incarnate Word, Rosenberg School of Optometry, in San Antonio, Texas USA, suggests that eating dark chocolate could improve visual clarity.
Bars with more than 72% cacao increase ocular blood flow which enhances macular function and sharpens the ability to read words and numbers.
The new research tested people 2 hours after eating 47g of 72% Cacao dark chocolate, and again after 40g milk chocolate in separate sessions more than 3 days apart. The testing looked at various aspects of visual performance.
More than 70% of people scored significantly higher after eating the dark chocolate. The biggest improvement was in contrast sensitivity, which helps us see in low light, or when text is poorly printed. Another area that improved was visual acuity – a measure of the sharpness of vision.
Cacao beans are rich in flavanol, an organic compound which improves blood flow in the brain and cardiovascular system and aids in reducing inflammation.
Researchers proposed increases in blood flow could explain the improvements, but suggested more work needs to be done to understand the exact mechanism. In the meantime we think it sounds like a good excuse to load up on dark chocolate and do some private testing. Sounds like a delicious experiment.
