Dark Chocolate and Vizion

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.

Benefits of Dark Chocolate

It is fitting with the holiday tomorrow that we look at some of the positive benefits of dark chocolate. It takes only two to three ounces of dark chocolate per week to achieve these benefits.

Dark chocolate is in the top 10 dietary sources of antioxidants, along with seasonings like cloves, mint, anise, cacao powder, black chokeberry, and black elderberry, according to the European Journal of Clinical Nutrition. Dark chocolate is also rich in bioactive flavanols and theobromine. These have good effects on the cells of our hearts and blood vessels.

The Journal of the American Heart Association research showed that eating dark chocolate helped people who have peripheral artery disease walk farther and longer.

Eating dark chocolate is linked to significantly lower blood pressure.  Systolic blood pressure (top number) for people who ate dark chocolate went down by three points. Diastolic (bottom number) blood pressure went down by two points.

Researchers followed a group of more than 37,000 men for 10 years and counted instances of stroke. The numbers showed that those who ate about 63 grams (2 oz.) of chocolate per week had a lower risk of stroke, compared with those who ate no chocolate. Five additional studies also showed lower stroke risk, on average by about 20 percent for chocolate eaters.

Those who had the dark chocolate saw an average drop of 12 percent in their LDL cholesterol, known as bad cholesterol, which is linked to higher risks of heart disease.

A June 2014 study found that eating dark chocolate helped people better cope with stress.

I could go on about the super benefits of dark chocolate covered bacon, but will save that for another day.
