The research, which was the first of its kind, found that just a small amount every month was enough to make a difference
It's not just carrots - eating grapes is good for your eyes as well, a new study reveals. Just a couple of handfuls of grapes a day for four months was shown to improve key markers of eye health.
The secret lies in the fact that a lot of degeneration of the eyes is down to oxidative stress and grapes are high in antioxidants. The team from the National University of Singapore took 34 adults who consumed either one and a half cups of grapes a day or a placebo for 16 weeks. The grape eaters showed a significant increase in macular pigment optical density , plasma antioxidant capacity, and total phenolic content compared to those on placebo. Those who didn’t consume grapes saw a significant increase in harmful ocular advanced glycation end products as measured in the skin.
The study, published in the journal Food & Function, said the key risk factors for eye disease include oxidative stress and high levels of AGE. The researchers found AGEs may contribute to many eye diseases by damaging the vascular components of the retina, impairing cellular function, and causing oxidative stress.
Study co-author Dr Jung Eun Kim said: “Our study is the first to show that grape consumption beneficially impacts eye health in humans which is very exciting, especially with a growing aging population. Grapes are an easy, accessible fruit that studies have shown can have a beneficial impact in normal amounts of just 1 ½ cups per day.
