want to see clearly? Cut out the meat

In his blog at NutritionFacts.org, Dr. Michael Greger reports on the link between plant-based diets and eysight: how just one serving of collard greens or kale per month can decrease the risk of glaucoma by 69%, and how cutting out meat can prevent cataracts:

The researchers conclude: “Overall, compared with meat eaters who consumed 100g meat and meat products/d[ay], fish eaters, vegetarians, and vegans had approximately 20%, 30%, and 40% lower risk of cataract, respectively.”

NutritionFacts.org is a great site. Also check out Dr. Greger's book Heart Failure - Diary of a Third Year Medical Student, available on-line, for some great insights into modern medical training.
