A new study says that drinking diet soda may raise the risk for a severe type of diabetic eye disease that can lead to blindness, WebMD reports.
The study was published in Clinical and Experimental Ophthalmology and is the first to evaluate the link between soft drinks and proliferative diabetic retinopathy.
“In our clinical sample of people with diabetes, consuming more than four cans, or 1.5 liters, of diet soft drinks per week was associated with a twofold increased risk of having proliferative diabetic retinopathy,” Eva Fenwick, PhD, told Medscape Medical News.
Fenwick is the study’s first author and a clinical research fellow at the Singapore Eye Research Institute and an assistant professor at the Duke-NUS Medical School in Singapore.
The study did not find the same results among those who drank regular, sugar-sweetened soft drinks.
