For the first time, researchers have demonstrated the value of this fruit, which is concentrated in antioxidants, in improving the eye health of the elderly.
Preserving vision is an important issue as we age. We know that certain foods such as carrotsspinach, blueberries or even the Cassis are renowned for their benefits on vision but not only. In a study carried out on 34 adults, researchers from the National University of Singapore were interested in a particular fruit, that we love eat from August to October and its effects on vision: grape. “THE oxidative stress is a key risk factor for impairment visual and consumption offoods rich in antioxidants can help manage visual impairments. However, a limited number of studies have investigated the effect of antioxidant-rich foods, including grapes, on eye health in older adults. they explain in the magazine Food&Function.
For their randomized, placebo-controlled trial of a duration of 16 weeksthey asked half of their volunteers to consume 46 g of powder freeze-dried grapes (i.e. about 1 and a half cups) per day and on the other the same quantity of powder of a placebo.
“This is the first time that we have demonstrated the impact of this fruit on eye health”
Scientists have regularly evaluated different indicators for examining eye health. Results: Regular consumption of grapes was associated with:
- a better protection of the retina against the harmful effects of light,
- a better protection of eye cells against damage linked to oxidative stress
- an increase in the total content of phenols (protective antioxidant compounds for eye tissues)
- to a higher intake of lutein, natural pigment good for the eyes
“Our study is the first to show that the consumption of grape has a beneficial impact on human eye healthwhich is very interesting, especially with a growing aging population”, said the study’s lead author, Dr. Jung Eun Kim. All that’s left is now!
