Chocolate can improve visual acuity in the short term
Chocolate is more than krotkot lasting pleasure. MoIt is believed to have a beneficial effect on cardiovascular function, especiallyolnie, if we are dealing with dark chocolate, that is, one thatora contains a large amount of cocoa.
Jeff Rabin and his team of cooco-workerow from the University of the Incarnate Word Rosenberg School of Optometry in San Antonio, USA, have discovered another benefit of it. Consumption of dark chocolate can krotk-term beneficial effects on vision. Research on this topic appeared on the lam „JAMA Ophthalmology”.
Researchers tested the effects of chocolate on 70 volunteers without any diseaseob eyes. Amongod ktorych were zaroBoth men and women, and the average age of the subjects was 26 years old. 30 people were given dark chocolate. Other participants were given milk chocolate with less cocoa. Then, after a period of twooch hours after ingestion, the participantow underwent an eye examination.
It turned out that the visual acuity of the subjects, whooThose who consumed dark chocolate significantly increased in poroIn comparison with the control group, whichora consumed milk chocolate. The increase in visual acuity reached 4 percent., and their perception contrastsoin 5 percent of. Up to 15 percent.
Why does it? Researchers believe that flavonoids, whichore found in cocoa in high amounts, they dilate blood vessels, thereby stimulating blood supply to the retinaowki, which improves the ability to see the targetoin low and high contrast.
With improved glucose and oxygen delivery, the eye and mozg can better process incoming signals. However, this positive effect quickly disappears. Already after twooch hours visual acuity returns to normal values.
– Further studies are needed to determine the length of these effectsow and their impact on performance in daily life – admitted the researchers.
