Vitamin C Rich Foods Decrease the Rate of Cataract Formation

Could increasing the amount of vitamin c rich food we eat decrease the rate at which cataracts form? Researchers suggest it can. Ophthalmology, published and study suggesting that the foods we eat have a greater impact, than genetics, on the development of cataracts. Researchers found that eating a diet consisting of vitamin c rich foods can reduce the risk of cataracts by one third.


Cataracts develop as we age and cause the lenses of our eyes to become cloudy reducing visibility and can eventual lead to the complete loss of vision. Although, surgery to remove cataracts is common cataracts are still the number one cause of blindness.


In the UK, researchers from King's College London, conducted a study in which they collected information from 1,000 pairs of female twins. The study conducted examined the role of nutrients and how both genetics and the environment affected the formation of cataracts. The 1,000 pairs of twins that participated in the study answered questions on a questionnaire regarding their diet in order to track their intake of many nutrients including vitamin C. When the participants were around the age of 60 years old researchers took digital images of their eyes which allowed them to examine the opacity of the lenses in their eyes. Measurements were repeated again 10 years later on a 324 pairs of twins.


Th first measurement obtained showed that eating a diet high in vitamin c lowered the risk of cataracts to about 20%. When the measurements were repeated 10years later researchers found that there was a 33% risk reduction in the women that were consuming diets high in vitamin C.


It has always been believed that genetics had the greatest impact on the development of cataracts. However, this study suggests that environmental factors have a greater impact on the progression of cataracts then genetics. Researchers found that genetics had an impact of 35% and environmental factors a 65% impact in the development of cataracts.


This study only focused on the consumption of vitamin c rich foods rather than vitamin c supplements. It may be the antioxident property of vitamin c that protects us from cataracts. Fluid already located in out eyes is rich in vitamin c which its role is to prevent oxidation that causes clouding of our lenses. Researchers think that the increase in the amount of vitamin c rich foods in our diet gives the vitamin c already located in our eyes a boost in return providing us with extra protection against cataracts.
