In a study involving older adults, the consumption of grapes was found to enhance the accumulation of macular pigment and suppress the expression of detrimental biomarkers. [1]
Consuming a higher quantity of grapes decreases levels of inflammatory proteins and elevates the presence of protective proteins in the retina.
In this article we will talk about the benefits of grapes for eye.
Benefits of Grapes for Eye
1: Antioxidants
Grapes are rich in antioxidants, such as flavonoids and resveratrol, which help combat oxidative stress in the eyes. Oxidative stress can contribute to age-related macular degeneration (AMD), cataracts, and other eye disorders.
2: Vitamin C
Grapes contain vitamin C, an essential nutrient that plays a role in maintaining the health of blood vessels in the eyes. This can contribute to a reduced risk of cataracts and other eye conditions.
3: Lutein and Zeaxanthin
These are carotenoids found in grapes, especially in the skin. Lutein and zeaxanthin are known to accumulate in the retina and may help protect the eyes from harmful high-energy light waves like ultraviolet rays. They are associated with a lower risk of AMD and cataracts.
4: Resveratrol
This compound, found in the skin of red grapes, has anti-inflammatory and antioxidant properties. It may help protect the retina from damage and reduce the risk of various eye conditions.
5: Collagen Formation
Grapes contain nutrients like proanthocyanidins that support the formation of collagen, a vital component of the cornea and other parts of the eye. Collagen is essential for maintaining the structure and strength of the eyes.
6: Blood Flow
Compounds in grapes, such as resveratrol, may promote better blood flow. Improved blood circulation can benefit the eyes by ensuring an adequate supply of nutrients and oxygen.
7: Prevention of Degenerative Conditions
Regular consumption of grapes may contribute to the prevention of degenerative eye conditions, including macular degeneration and diabetic retinopathy.
Research Findings
In addition to the above, here are some specific research findings that support the benefits of grapes for eye health:
- A study published in the journal “Ophthalmology” found that grape consumption increased macular pigment density (MPOD) in older adults. MPOD is a measure of the amount of protective pigments in the macula. Higher MPOD levels have been associated with a lower risk of AMD.
- Another study published in the journal “Investigative Ophthalmology & Visual Science” found that resveratrol may help protect against glaucoma by reducing the pressure inside the eye.
- A study published in the journal “Nutrition and Metabolism” found that grape consumption may improve visual function in people with diabetes.
