Many older people know that lutein is good for the eyes, but what are the specific benefits of this substance, and in which foods is it generally found?
There is a pigmented area in the posterior pole of the retina, which appears yellow due to its high concentration of lutein. This is what we commonly call the "macula." Lutein is a type of carotenoid with certain antioxidant properties. It can block the blue light that damages the eyes, protecting the macula of the retina from harm and maintaining visual acuity and clarity. Some studies have found that increasing lutein intake can reduce the incidence of cataracts. Green leafy vegetables and orange-colored fruits and vegetables are good sources of lutein, such as kale, broccoli, spinach, romaine lettuce, bok choy, carrots, pumpkins, and mangoes.
