Good news for dark chocolate lovers. Researchers
had 30 healthy adults, averaging 26 years old; 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 did not know
what type of chocolate they were eating.
About two hours later, each participant underwent vision testing
using standard letter-based eye charts. Compared to people who
ate the milk chocolate bar, those who snacked on the dark
chocolate showed "small enhancements in visual acuity and
large-letter contrast" on the vision test, the researchers
reported.
Heart-healthy compounds in chocolate called flavanols appeared
to sharpen eyesight. The observed change in vision was small,
but significant. Prior studies showed 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. The study results were published April 26, 2018 in
JAMA Ophthalmology.
