Everybody knows that eating carrots is good our eyesight. A new study suggests that grapes are also good our eyes. Researchers the National University of Singapore have found that eating just a few grapes a day can improve our vision. This is especially so people who are older. Dr Eun Kim, the lead researcher, said: "Our study is the first to show that grape consumption beneficially impacts eye health humans, which is very exciting, especially a growing, ageing population." Dr Kim added that, "grapes are an easily accessible fruit that studies have shown can have a beneficial impact" our eyesight. This is good news people who don't really like carrots.
The study is published the journal "Food & Function". Thirty-four adults took part a series of experiments over 16 weeks. Half the participants ate one-and-a-half cups grapes per day; the other half ate a placebo 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 the retina. The retina passes information light to the brain electrical signals. It protects the eyes damaging blue light. A lot blue light comes from computer and smartphone screens, and LED lights.
