Vitamin K reduces cataract

Chances for cataract increase with age and can lead to blindness. Recent evidence suggests inflammation and oxidative stress play a role, leading doctors to consider antioxidants as a preventative.

In this study, 5,860 older men and women with higher chances of heart and circulatory problems told doctors their daily diets each year, over a six-year follow-up period. Doctors were particularly interested in the antioxidant vitamin K1, found in green leafy vegetables, Brussels sprouts, and fermented dairy products. Measuring the amount of vitamin K1 in the diet, doctors found those who got at least 497 mcg of vitamin K1 per day were 29 percent less likely to need cataract surgery compared to those who got less than 250 mcg of vitamin K1 per day.
