Which is better, lutein or carotene?
Lutein is called carotene, which shows that lutein and lutein have similar effects on retina of eyes. Carotene and lutein have very strong antioxidant capacity. Can help the retina from being damaged by strong light, and has a very significant effect on promoting the regeneration of rhodopsin in retinal cells. Therefore, it plays an irreplaceable role in preventing severe myopia and retinal detachment.
The difference between lutein and carotene
Lutein is actually a carotenoid, which usually exists in carotene. Therefore, their functions are similar in some parts. They all promote the formation of rhodopsin in the eyes, which can protect the eyes from light damage, prevent myopia and prevent blindness. In addition, lutein can also prevent coronary heart disease, cardiovascular sclerosis and other diseases.
Carotene has many other functions. It is not only a natural eye drop, but also can enhance human immunity, maintain the function of muscles and internal organs, and improve the vitality of male sperm. So what can you eat to make your eyes better? Kiwifruit, corn, egg yolk and grapes, if eaten regularly, are of great help to the health of eyes.
Is lutein a carotene?
Regarding whether carotene is lutein, lutein is actually a kind of carotene, that is, lutein exists in carotene. Of course, carotene and lutein are very different in molecular structure, so we can judge. Lutein, also known as "plant lutein", coexists with zeaxanthin in nature. It is very beneficial to human health, which is also an essential nutrient for many plants, so it is also very important to nature. However, our human body cannot directly synthesize lutein, so we need to eat more vegetables rich in carotene, which naturally supplements lutein.
Lutein and carotene have a good collocation effect.
Beta-carotene: Beta-carotene is an effective biological antioxidant, which can be converted into vitamin A in human body, and this conversion will only be realized when necessary, so beta-carotene is a safe source of vitamin A. Many people know that vitamin A is a component of photosensitive substances in visual cells. When vitamin A is deficient, the adaptability of eyes to dark environment decreases, and it is easy to suffer from night blindness in severe cases. Vitamin A can protect the tissue and structure of eyes, maintain the normal efficacy of rhodopsin, and prevent and treat night blindness and dry eye.
Lutein: Lutein has antioxidant and photoprotective effects, and plays a role in protecting eyesight. Optic nerve is non-renewable and vulnerable to harmful free radicals. The antioxidant effect of lutein can inhibit the formation of harmful free radicals and reduce the damage of oxidative stress to eyes. Another photoprotective effect is that it can absorb a lot of blue light, prevent macular oxidative damage, and protect macular from damage.
It can be said that both β -carotene and lutein have irreplaceable effects on eyes, so there is no comparability. On the contrary, the combination of the two is more conducive to eye health.
