We've all heard the many benefits of a vegetarian or vegan diet. Results of a recent University of Oxford study may add one more to that list: reduced risk of cataracts.
A cataract is a cloudiness on the eye's lens that, as it worsens, can severely impair vision. Most people (if they live long enough) will eventually develop cataracts. A cataract is treated by removing the eyes natural lens and replacing it with a manufactured, intraocular lens (IOL).
Just under 28,000 subjects participated in the study. Subjects were broken into categories of high meat consumers (3.5 or more ounces per day), mid-level meat consumers (1.7-3.4 ounces per day), low meat consumers (less than 1.7 ounces per day), fish eaters (who did not eat meat), vegetarians (ate dairy but not meat), and vegans (no meat, fish, or dairy).
From 1993-1999, subjects (all over 40) were surveyed on their dietary intakes. In 2008 and 2009, these same subjects were evaluated for cataracts. A total of 1500 subject developed cataracts.
The study's results showed a link between low meat consumption (compared to the high meat consumers) and reduced risk for cataracts. The breakdown is as follows:
Diet Group | Reduced Risk of Cataracts |
---|---|
Mid-level meat eaters | 4% |
Low meat eaters | 15% |
Fish eaters | 21% |
Vegetarians | 30% |
Vegans | 40% |
And so we have another reason to go veggie. Although the thought of replacing my imperfect natural lenses with vision-correcting IOLs is appealing too. Let's hope we all live long enough to develop (or not develop) cataracts.
