Vitamin C May Protect Against Cataracts
Cataracts are a clouding of the lens in the eye that lead to a decrease in vision. A recent study suggests that vitamin C may help protect against the progression of cataracts.
Participants in the study included 324 pairs of female twins. Photographs were taken of all of the women’s eyes in order to show the opacity of the lens. Vitamin C intake was measured via a food frequency questionnaire. There was a mean follow-up of 9.4 years between the initial examination and follow-up examination.
After examining the data and taking lifestyle factors into account, the researchers found that those with the greatest dietary vitamin C intake had a 33% reduction in the risk of cataract progression compared to those with the lowest intake.
Researchers from Kings College in London led the study. It was published online ahead of print on March 23, 2016, in the journal Ophthalmology.
Vitamin C is an essential nutrient that has been linked to numerous other health benefits including heart health, brain health, eye health and improved mood. It can be found in high levels in citrus fruits and dark leafy greens such as cantaloupe, oranges, kiwis, and papaya, and in dark leafy greens such as broccoli and kale.
