Researchers find association between carbohydrate intake and glaucoma

Spanish scientists report higher levels of glaucoma among study participants with a diet rich in carbohydrates


Research published in the European Journal of Ophthalmology has highlighted an association between a diet high in carbohydrates and glaucoma.

The study involved 18,247 participants, who were followed over the course of 10 years.

Their carbohydrate intake at the start of the study was collected and classified into nine different carbohydrate food sources.

A self-reported glaucoma diagnosis was collected both at the start of the study and at biannual follow ups. Potential confounders, including diabetic status, were taken into account by researchers.

During the 10-year period, a total of 242 new cases of glaucoma were identified.

After excluding diabetes cases, the scientists found that participants with the highest carbohydrate intake had a 77% greater risk of developing glaucoma compared to those with the lowest carbohydrate intake.

None of the nine carbohydrate food groups were individually related to glaucoma.

“The total amount of carbohydrate, rather than the specific food sources of carbohydrate, seems to play a major role,” the researchers stated.
