Lutein is a carotenoid vitamin, similar to vitamin A and beta-carotene. Foods rich in lutein are mostly green leafy vegetables such as kale and spinach, but it can also be found in kiwi, broccoli, corn, and some animal products like egg yolk and animal fat.
It is also called “the eye vitamin”, and is actually found as a color pigment. Lutein protects the eye from sun damage and oxidative stress. In many cases, lutein was found to be indispensable when it comes to preventing cataract, retinitis pigmentosa and macular degeneration.
Researches suggest that lutein, like other carotenoids, can prevent a heat stroke and a heart attack. It also reduces the harmful effect that cholesterol has on the walls of the blood vessels. Lab tests on animals which were given lutein showed that the animals were less likely to have atherosclerosis.
A POWERFUL ANTIOXIDANT
Lutein is a powerful antioxidant which fights off the free radicals that cause numerous diseases and health issues.
Researches related to lutein’s effect on cancer have given mixed results. Certain reports link lutein with a lower risk of getting a cervical, prostate and colon cancer, while other reports show no benefits for lung and other types of cancer. It is most likely that lutein’s antioxidant properties are only useful for certain types of cancer.
