Vitamin C helps reduce the risk of cataracts

(suckhoevadoisong.net) Elderly people who eat less vitamin C-rich foods in their daily diet will have an increased risk of cataracts, a study in India shows.

Cataract or cataract is a condition in which the membrane covering the lens is formed by protein clumps, causing vision problems for the elderly. Some studies show that people who eat more foods rich in antioxidants, including vitamin C, have a lower risk of disease.
But these studies are done by European countries, not suitable for low-income countries like India, where vitamin C levels in the body tend to be very low and the incidence of cataracts is particular. high.
In the latest study, Indian researchers examined the eyes of 5,600 elderly people over 60 years old and at risk for cataracts. They also interviewed these people about their diets and lifestyle habits and measured vitamin C levels in their blood.
The results showed that nearly 73% of the study participants had cataracts and it was proportional to the amount of vitamin C in the blood as well as the daily intake. Specifically, a quarter of elderly people with the highest vitamin C intake (38 micromole / l), the risk of cataracts was 39% lower than those who ate foods with the least vitamin C. Factors such as income, smoking habits, high blood pressure and diabetes are also taken into account.
The standard amount of vitamin C in the blood is from 11 micromole / l of blood. Below this level is considered vitamin C deficiency.
According to the recommendations of experts, taking vitamin C supplements will not be able to replace a reasonable diet with many foods rich in vitamin C such as oranges, grapefruit, bell peppers. green and red, kiwi, berries, broccoli and tomatoes.
