Vitamin A and Vision Health

Posted by Chantel M. Contributed by US National Library of Medicine National Institutes of Health

Vitamin A
is a general term of Vitamin A Retinol, retinal, beta-carotene, alpha-carotene, gamma-carotene, and beta-cryptoxanthin best known for its function for vision health and antioxidant scavenger and essential for growth and differentiation of a number of cells and tissues.
According to the study of "The intake of carotenoids in an older Australian population: The Blue Mountains Eye Study" by Manzi F, Flood V, Webb K, Mitchell P., posted in US National Library of Medicine National Institutes of Health, researchers found that Vitamin A intake in this population is high relative to the Australian Recommended Dietary Intake. Carotenoid intakes, particularly beta-carotene, make a substantial contribution, particularly from fruit and vegetables. This study provides important information as a basis for examining associations between dietary carotenoid intake and eye disease in the BMES.
