Dietary sodium and cataracts

A high dietary sodium (salt) diet increases the risk of posterior subcapsular cataracts, according to Australian researchers.

A study of over 2,100 subjects revealed that those with the highest sodium intake were at approximately twice the risk of posterior subcapsular cataracts.

They conclude that a low salt diet may help prevent cataract development in elderly persons (American Journal of Epidemiology 151:524-626, 2000)

Posterior subcapsular cataracts cause the most vision loss of all cataract types.

It has been estimated that 70 percent of women and 60 percent of men over the age of 80 suffer cataracts.
