Fruit en blindness
Study of fruits, vegetables, vitamins and
carotenoids found that only fruit produced significant decrease in risk in condition that
causes blindness. Intake of antioxidant vitamins and carotenoids have been commonly
thought to reduce the risk of age-related macular degeneration (AMD), the leading cause of
vision loss in older adults. However, few studies have examined intake of fruits and
vegetables in relationship to this condition. Researchers at Brigham and Women’s
Hospital (BWH) analyzed consumption of fruits, vegetables, vitamins and carotenoids by
people 50-years-old and older and their individual impact on several stages of AMD –
including neovascular AMD, one of the most severe forms of the disease – and have
found that fruits decrease the risk for this condition. In addition, researchers have
found that vegetables, vitamins and carotenoids did not reduce risk as is commonly
thought.
According to lead author Eunyoung Cho,
ScD, a researcher from BWH and an instructor in Medicine at Harvard Medical School (HMS),
“People are living longer, healthier lives and age-related illnesses, such as
blindness, can significantly impact an otherwise healthy quality of life. Because there
are a limited number of treatment options for age-related macular degeneration, clinicians
and researchers have been focused on identifying factors that reduce risk and can
ultimately save a person’s eyesight. This study, the first large-scale look at
dietary intake and impact on AMD risk, points researchers to the health benefits of fruit
and the role certain fruits play in helping reduce risks associated with this debilitating
condition.”
