Benefits of Kale
Incorporate kale juice into your diet to keep your eyesight sharp. The vitamin A in kale helps you see at night, and it plays a key role in your ability to detect light. The juice also contains lutein and zeaxanthin, two nutrients that promote long term eye health by filtering harmful light rays as they enter your eye, preventing those rays from reaching the sensitive tissues within your eyes. A quarter cup portion of kale juice provides 7,033 international units of vitamin A, which is more than enough to fulfill your recommended daily intake. Each serving of kale juice also provides 5.8 milligrams of lutein and zeaxanthin, or just shy of half the daily intake suggested by the American Optometric Association.
