Dark Chocolate

It may not replace prescription glasses, but a few bites of dark chocolate might offer a slight and temporary bump up in vision quality, new research suggests.

Heart-healthy compounds in chocolate called flavanols appeared to sharpen eyesight for a group of 30 healthy young adults in the new study.

The observed change in vision was small but significant. However, the study authors stressed that it’s too early for ophthalmologists to recommend chocolate as medicine for the eyes.

“The duration of these effects and their influence in real-world performance await further testing,” said a team led by Dr. Jeff Rabin of the University of the Incarnate Word in San Antonio, Texas. His team published its results online April 26 in JAMA Ophthalmology.

As Rabin’s team explained, there’s been evidence in prior studies that the antioxidant flavanols in dark chocolate might help boost blood flow to the nervous system, boost heart function and even help preserve the aging brain.

So, the investigators wondered if the eyes might reap some sort of benefit from chocolate, too. To find out, the researchers had 30 healthy adults, averaging 26 years of age, eat either a 1.5-ounce Trader Joe’s 72 percent Cacao Dark Chocolate bar or a similar-sized Trader Joe’s Crispy Rice Milk Chocolate bar. Labels were removed from each bar so participants didn’t know what type of chocolate they were eating.

About two hours later, each participant underwent vision testing using standard letter-based eye charts. The result? Compared to people who’d eaten the milk chocolate bar, those who’d snacked on the dark chocolate showed “small enhancements in visual acuity and large-letter contrast” on the vision test, the researchers reported.

    Researchers suggest that dark chocolate could improve vision and it is true. It is believed that these flavonoids are largely responsible for some of the potential health benefits of dark chocolate consumption, which include better cognitive functioning and improved heart health. By the way, I have pleased to read the entirety of the post. Thanks for the posting.

    Any excuse to eating chocolate is great, and when it also has health benefits to your eyes it is even better. Unlike milk and white chocolate, dark chocolate has a higher proportion of cocoa and this is where a lot of the health benefits come from. Dark chocolate is still high in sugar and fat, but when eaten in moderation can provide a healthy source of iron, copper, magnesium, fibre, zinc, manganese, and selenium, and cocoa offers copious amounts of antioxidants, flavonoids and flavones.

    Dark chocolate is good for many things, including the heart too, but the one with the high amount of cocoa in it, such as Hershey’s Kisses. It is said that only two kisses per day an lower blood pressure.
