According to a recent study published in the June issue of Physiology and Behavior, eating dark chocolate may better your eyesight. In an online article, MSNBC stated, ʺDark chocolate might improve your ability to see in low-contrast situations, such as poor weather.ʺ
If you suffer from low-contrast sensitivity, also known as low-contrast situations or functional vision, you may need extra light to read or have issues with night driving. As one website stated, think of it as your ʺcrispness of vision.ʺ
But, before you invade the candy counter or eat a box of chocolate remember the study said, ʺEating one ounce or two small dark chocolate squares improves the blood flow to the retina up to several hours after consumption.ʺ
The University of Reading researchers believe it is the cocoa, or cacoa flavanols in dark chocolate, which may improve vision. Yes ladies and gentleman, flavonols, also known as flavonoids, are our friends. Flavonols can be found in the following food items:
• green tea
• black tea
• red wine
Flavonols have recently been in the news for their health benefits. According to RealAge.com, ʺFlavonoids are plant-based compounds with powerful antioxidant properties.ʺ
England’s University of Reading researchers conducted the study with 30 women and men between the ages of 18 to 25.
First, the candidates ate a dark chocolate bar with high contents of flavanols and were tested two hours later for vision and cognitive performance. One week later, the candidates ate a white chocolate bar with very low contents of flavanols and were tested two hours later for vision and cognitive performance.
The Reading research team noted, they tested the candidates with an eye test ʺby reading more numbers that become progressively more similar in their luminance to their background.ʺ
The results: ʺResearchers found cocoa flavanols improved visual contrast sensitivity and reduced the time required to detect motion direction.ʺ
According to MSNBC, ʺOther research suggests cocoa flavanol’s positive impact on blood flow is even greater in folks over the age of 25.ʺ
