Australian researchers found that if the salt content of food is too high, the possibility of suffering from cataract increases. Cataract refers to whitening of the lens, which can lead to blindness if left untreated.

Dr. Robert G. Camin of the University of Sydney and colleagues found that people with the highest sodium intake are twice as likely to have a posterior capsular cataract than those who have the lowest sodium intake. This is the most serious visual impairment. cataract. Their research report was published in the recently published "American Epidemiology" magazine.

The researchers examined the eyes of approximately 3,000 adults aged 49 to 97 years and asked the subjects to fill out a questionnaire about dietary frequency. 160 people had a posterior capsular cataract, and 970 people had one of the other two cataracts unrelated to sodium intake.

The study also found that people with high salt intake may also suffer from other cataract-prone diseases, such as diabetes or high blood pressure, and may have taken a corticosteroid anti-inflammatory drug.
