"Eating carrots is good for our eyes," and now, researchers say grapes are good too. A study by the National University of Singapore found that even a few grapes each day can help us see better, especially if we're older. Dr. Eun Kim, the lead researcher, said, "Our study is the first to show that grapes can help our eyes, which is very exciting, especially for older people." Dr. Kim also mentioned that grapes are an easy fruit to eat and can help our eyes. This is great news for people who don't like carrots.
The study was published in the journal "Food & Function." It involved 34 adults over 16 weeks. Half of them ate 1.5 cups of grapes a day, and the other half had a different snack. Dr Kim did not tell the participants or the researchers whether she was testing the grapes or the snack. She thought that not revealing this information would give better test results. She found that people who ate the grapes had improved muscle strength around the retina. The retina passes information about light to the brain via electrical signals. It protects the eyes from damaging blue light. A lot of blue light comes from computer and smartphone screens, and from LED lights.
