Lutein & Cataracts

Tagged:  

Women who consume more lutein (and its cousin, zeaxanthin) have a lower risk of cataracts.

Researchers tracked more than 35,000 women who were enrolled in the Women's Health Study. Those who consumed the most lutein and zeaxanthin (they averaged 6,700 micrograms a day) had an 18 percent lower risk of cataracts over the next 10 years than those who consumed the least.

The best source of lutein and zeaxanthin: green leafy vegetables.

What to do: It's worth eating more leafy greens like spinach and kale. Even if they don't protect your eyes, they're packed with vitamins and minerals, but not calories.
