Can you distinguish between lutein and carotene ?
Lutein is one of several main carotenoids in plasma, which is evenly distributed in high-density lipoprotein and lipoprotein. Lutein esters in food are produced in the small intestine through the combined action of bile and pancreatic lipase, which is absorbed by the small intestinal mucosa. Lutein, also known as "phytolutein", coexists with zeaxanthin in nature. It is the main component of plant pigments such as corn, fruits, vegetables, flowers, etc. It is also the main pigment that constitutes the macular region of the human eye.
Lutein, as an important antioxidant, is a member of the carotenoid family, also known as "phytolutein." Human eyes contain high amounts of lutein, which cannot be produced by the human body. It must be supplemented by intake of lutein. If it is lacking in this element, the eyes will cause blindness.
Lutein has an important protective effect on the macula in the retina. If it is lacking, it can easily lead to macular degeneration and blurred vision. Then there are symptoms such as vision deterioration and myopia. Lutein is the precursor of NA and can be converted to VA in the human body. The main physiological function of lutein for the eyes is as an antioxidant and photoprotective effect. The optic nerve cannot be regenerated and is easily damaged by harmful free radicals. The antioxidant effect of lutein can prevent the formation of harmful free radicals.

Lutein can absorb a lot of blue light. The wavelength of blue visible light is very close to ultraviolet light, and it is a potentially harmful light that can reach the retina. Before reaching the sensitive cells on the retina, the light will pass through the high concentration area of lutein. At this time, if the lutein contained in the macula is rich, this damage can be minimized.
Carotene is an effective biological antioxidant that can remove free radicals in the body, improve immunity, prevent cancer, atherosclerosis, thrombosis, and anti-aging. After ingested in the digestive organs of the human body, it can be converted into vitamin A, which is the current vitamin A supplement product (simple supplementation of chemically synthesized vitamin A will cause people to be poisoned when excessive). It can maintain the health of eyes and skin, improve night blindness and rough skin conditions, and help the body protect the body from free radical damage. It should not be taken at the same time with acidic substances such as vinegar.
