Lutein is concentrated mostly in the macula, the part with the yellow oval located near the center of the human eye retina.
Lutein is primarily responsible for human vision. Lutein protects the macula in the eye from oxidative stress and helps the absorption of blue light.
Research shows that a considerable amount of lutein may reduce the risk of eye disease macular degeneration in particular.
Lutein also play an important role in preventing eye disease called Harbinger's brush, a phenomenon in which the eye sees color polarized light.
Macular yellow color due to the presence of lutein eye will give the ability to absorb blue and ultraviolet excess light entering the eye.
It serves as a kind of natural sunscreen for the retina and the surrounding area.
Lutein can be obtained from green leafy vegetables such as spinach and kale, egg yolks, and animal fats.
People with a diet low in lutein can take supplements to meet the body's need for lutein.
Although there is currently no provision for the recommended daily dose, taking 6-10 mg / day is considered a safe dose.
In addition to kale and spinach, vegetables that have a very high content of lutein are peas, zucchini, brussel sprouts, pistachio nuts, broccoli, corn, kiwi fruit, radishes, romaine lettuce, collard greens, and eggs.
