New Study claims Vitamin C Intake protects against Cataract Progression – PerfScience
A new study has suggested that vitamin C not only prevents you from colds, but also helps in warding off cataracts, clouding of the normally clear lens of an eye.
People who prefer eating diet rich with the nutrient can decrease their chances of suffering from cataract progression by more than 30%, as per a study published Wednesday in the journal Ophthalmology. It is the first research that links cataract development and diet.
A number of people around the globe suffer from cataract. It is a disease that occurs naturally with age, as per health experts. In this, an area of a person’s eye becomes less clear. According to health experts, cataracts can be removed, but they are still the major cause of blindness in the world.
For the new study, researchers examined over a thousand pairs of British female twins. All the participants were 60 years old. Those who included vitamin C in high amounts in their diet had about 33% less chances of developing cataract in next one decade, as per the researchers.
The researchers also mentioned that they didn’t find any association between vitamin C supplement and reduced the risk of the disease. The study has just linked intake of vitamin C and the disease, and didn’t prove cause-and-effect relationship between the two.
It is not possible to prevent cataracts totally, but they can be delayed with diet rich in vitamin C, said Dr. Christopher Hammond, a professor of ophthalmology at Kings College London and lead researcher of the study. “The most important finding was that vitamin C intake from food seemed to protect against cataract progression”, Hammond added.
The researchers believe that a diet rich in vitamin C can boost the amount of the vitamin in the eye fluid and delay the disease.
According to a report in CBS NEWS by Robert Preidt, “While many believe that vitamin C helps ward off colds, a new study suggests the nutrient might prevent something more serious — cataracts.”
“While we cannot totally avoid developing cataracts, we may be able to delay their onset and keep them from worsening significantly by eating a diet rich in vitamin C,” study lead researcher Dr. Christopher Hammond said in a news release from the journal Ophthalmology.
“The team examined data from more than 1,000 pairs of female twins from the United Kingdom. Participants answered a food questionnaire to track the intake of vitamin C and other nutrients, including vitamins A, B, D, E, copper, manganese and zinc. To measure the progression of cataracts, digital imaging was used to check the opacity of their lenses at around 60 years old. They performed a follow-up measurement on 324 pairs of the twins about 10 years later,” according to a news report published by Natural Products Insider.
“The most important finding was that vitamin C intake from food seemed to protect against cataract progression,” said study author Christopher Hammond, M. D., FRCOphth, professor of ophthalmology at King’s College London. “While we cannot totally avoid developing cataracts, we may be able to delay their onset and keep them from worsening significantly by eating a diet rich in vitamin C.”
In a report published by the NY Times, “The study participants underwent digital imaging of the eye to measure the progression of cataracts. The researchers found that women who consumed diets rich in vitamin C and who ate about two servings of fruit and two servings of vegetables a day had a 20 percent lower risk of cataracts than those who ate a less nutrient-rich diet.”
“We found no beneficial effect from supplements, only from the vitamin C in the diet,” said Dr. Christopher Hammond, a professor of ophthalmology at King’s College London and an author of the study, published in Ophthalmology. Foods high in vitamin C include oranges, cantaloupe, kiwi, broccoli and dark leafy greens.
