According to research, an older population is more likely to develop eye illness and vision issues. The most common risk factors are:
AGEs may contribute to a variety of eye diseases by destroying the retina’s vascular components, affecting cellular function, and creating oxidative stress.
Dietary antioxidants can reduce oxidative stress and limit the development of AGEs, perhaps benefiting the retina by improving Macular Pigment Optical Density (MPOD). Grapes are high in antioxidants and other polyphenols.
For 16 weeks, 34 human volunteers were given either grapes (equal to 12 cups of grapes per day) or a placebo. When compared to the placebo group, grape eaters had a substantial increase in MPOD, plasma antioxidant capacity, and total phenolic content. Those who did not consume grapes had much higher levels of dangerous AGEs in their skin.
Grapes Impact Eye Health
“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,” said Dr. Jung Eun Kim. “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.”
