The source and physiological functions of lutein



Lutein is found mainly in vegetables, although it is a carotenoid,  but carrots are not the best source of lutein.The more dark green  vegetables, the higher the content of lutein.Such as broccoli, green  cauliflower, spinach, asparagus, green lettuce, etc., are rich in  lutein.The yolk is also a good lutein provider.



Natural lutein is an excellent antioxidant, can resist free radicals  in the human body cell and organ damage, which can prevent the  body's aging caused by cardiovascular hardening, coronary heart  disease and cancer, etc.Lutein and zeaxanthin are the only two types  of carotenoids in the eye, preventing the loss of vision and  blindness caused by age-related macular degeneration, which is a  unique function of lutein.


The carotenoids found in the human body mainly consist of a  carotenoid, a carotenoid, cryptoxanthin, lutein, lycopene, and  anisoflavin.Medical experiments show that the natural lutein in  plants is an excellent antioxidant.The addition of a certain amount  of lutein in food can prevent the senescence of cells and the aging  of body organs, and also prevent the vision loss and blindness  caused by age-related macular degeneration.Through a series of  medical studies, carotenoids have been recommended for use as cancer  prophylaxis, life-prolonging agents, ulcerative agents, heart  attacks and the arrival of coronary artery disease.At the same time,  lutein can be used as a feed additive for the coloring of poultry  eggs, and it has also been used in the food industry for coloring  and nutrition.
