Spinach, Collard Greens, and Less Blindness

 

One path to better long term visual health may be paved with spinach and collard greens.  This is Dr. Steven Andrew Davis, Speaking of Health.  You’ve been told to eat carrots because they’re good for your eyes?  Actually, a Harvard Medical School study suggests that carotenoids, a substance found in a variety of vegetables, may actually lower an adult’s risk for a certain type of blindness.

 

The disease is called age-related macular degeneration, and it’s a leading cause of blindness in adults.  In research published in the Journal of the AMA investigators from 5 cities found that patients with very high intakes of carotenoids had a 43% lower risk of macular degeneration than those who had the lowest intake of carotenoids.  The strongest association among the various carotenoids were those obtained from dark green, leafy vegetables, particularly spinach and collard greens.  While a protective effect of carotenoids was noted, vitamin supplements, as a group, did not appear to reduce the risk of age-related macular degeneration although, notes the research team, “a small benefit cannot be ruled out for vitamin C and multivitamins.”  They do say, however, that “the segment of the population older than age 65” is our fastest growing, and so the prevalence and impact of this eye disease will continue to increase.  Identifying eye disease will continue to increase.  Identifying strategies, like dietary approaches could help prevent or retard the onset of this visual disorder which can cause blindness or decreased vision among the elderly.
