Lutein has the effect of relieving eye fatigue in our daily life. So, does eating lutein have side effects? Let's talk together.
Lutein ester is an important carotenoid fatty acid ester. Most lutein esters existing in nature can be divided into trans lutein esters and cis lutein esters, and all of them are mainly in all-trans molecular configuration. All-trans lutein esters can be divided into lutein monoester and lutein diester. It is widely found in marigold flowers, pumpkins, kale, Polygonum multiflorum and other plants. Among them, it is the most abundant in marigold flowers, up to 30% to 40%. After people eat lutein capsules, it takes two weeks to detect the increase of lutein concentration in the blood, and it takes up to two months to detect it in the macular area of the eye. This shows that lutein needs to go through a long transportation process, during which not only the eyes of the body are supplemented with lutein, but also other tissues are forced to supplement it.
A large amount of lutein is gathered in the macula of human retina, which is the center of human vision. Lutein has a great effect on eyes, which can protect eyes from being damaged by blue light and other high-energy light. Studies have shown that adequate intake of lutein can ensure adequate pigmentation in the macula of the eye and help prevent age-related macular degeneration (AMD). Lutein ester is rich in vitamin A, anthocyanin, lutein and so on. These components still have a very good effect on relieving visual fatigue, protecting visual health and relieving eye discomfort, so lutein ester should have a good effect on eye diseases. High myopia is prone to retinal detachment, hydrops, floaters, etc., and even lead to permanent blindness. Supplementing enough lutein can make the eyes have enough nutrition and reduce the occurrence of lesions.
It takes a long time to eat lutein and finally transport the leaf yellow nutrients to the eyes. To supplement lutein by eating, the [5] lutein capsules need to be absorbed through the gastrointestinal tract, enter the liver through the chylous duct, and be transported to the macula of the eye after the liver is detoxified. Moreover, lutein itself is a fat-soluble substance, and it needs high-density lipoprotein (HDL) in the blood to be transported to the macular area of the eye. The lack of lutein can lead to blurred vision, even blindness. Lutein has strong antioxidant and photoprotective effects, which can promote the regeneration of rhodopsin in retina, protect vision, filter the blue light caused by electronic products and relieve eye fatigue. Because the human body cannot synthesize lutein independently, it needs to be supplemented regularly and quantitatively every day, and lutein ester is very easy to be absorbed and utilized by the human body, so the absorption effect is the best.
Usually, you can eat more green vegetables and fruits to supplement lutein, such as corn, egg yolk, cabbage, kiwi fruit, tomatoes, etc., but the absorption and utilization rate is not very ideal. It is recommended to choose a reliable lutein dietary supplement. Lutein is usually eaten for a long time. Lutein is an important nutrient element in the retina of the eye, which can effectively filter harmful light such as blue light and radiation, and protect the photoreceptor cells in the retina. Lutein has strong antioxidant properties, which can reduce free radicals in the body, relieve eye fatigue and prevent eye diseases. Blue light is a kind of visible light that can reach the highest energy of retina, which will cause a chain of harmful chemical reactions between retinal pigment epithelium and photoreceptor cells, resulting in structural damage of retinal cells. The maximum absorption wavelength of lutein is just within the wavelength range of blue light, which can form a blue light filter in the retina, reduce the probability of blue light reaching photoreceptors and nerve cells, and protect the retina.
