Reviewed by Danielle Ellis, B.Sc.Oct 6 2023 In a recent randomized, controlled human study, consuming grapes for 16 weeks improved key markers of eye health in older adults. The study, published in the scientific journal Food & Function looked at the impact of regular consumption of grapes on macular pigment accumulation and other biomarkers of eye health.
Science has shown that an aging population has a higher risk of eye disease and vision problems. Key risk factors for eye disease include 1) oxidative stress and 2) high levels of ocular advanced glycation end products . AGEs may contribute to many eye diseases by damaging the vascular components of the retina, impairing cellular function, and causing oxidative stress.
In this new study, 34 human subjects consumed either grapes or a placebo for 16 weeks. The grape eaters showed a significant increase in MPOD, plasma antioxidant capacity, and total phenolic content compared to those on placebo. Those who didn't consume grapes saw a significant increase in harmful AGEs, as measured in the skin.
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."Journal reference:Hu, W., et al.
