Key nutrient "can prevent cataracts"

Key nutrient "can prevent cataracts"

Experts have found that a key nutrient may be able to prevent cataracts, offering hope to the millions of people worldwide who suffer from the eye condition.

Eye specialists at the University of East Anglia (UEA) have published research in the American Journal of Physiology - Regulatory, Integrative and Comparative Physiology which shows how the nutrient histidine, when added to the diet of farmed salmon, stops cataracts from forming.

Lead author Dr Jeremy Rhodes, from the Norwich Eye Research group at UEA, said histidine is present in high quantities in blood meal but was deficient in the post 1990s diet. However, by adding histidine to the salmon"s diet, cataracts could be prevented.

"In this paper, the latest of several from the project, we show that histidine has a protective role in the lenses of salmon, enabling them to withstand the considerable environmental stresses that their life cycle demands," he explained.

Other research published in the Journal of AAPOS, the official publication of the American Association of Pediatric Ophthalmology and Strabismus, has showed that feeding infants one hour before an eye exam reduces stress.
