In modern life, we are paying more and more attention to the importance of vision. However, with the popularity of electronic products and the Xi of facing screens for long periods of time, eye health problems are also increasing. As an important nutrient, lutein is known as "gold". A number of scientific studies have also confirmed the efficacy of lutein in protecting the eyes and preventing eye diseases, such as macular degeneration and cataracts.
Lutein is a natural carotenoid, which is a fat-soluble antioxidant with a yellow color and a high degree of eye and health protection.
Efficacy and role of lutein
1. Antioxidant capacity:
Lutein has a powerful antioxidant capacity, which can neutralize free radicals and reduce oxidative stress damage to cells. It is able to protect the retina in the eye from ultraviolet rays and other harmful substances, preventing or slowing down the development of eye diseases.
2. Protect eyesight:
Lutein is an important component in the retina, absorbing blue light and providing the protection needed by the eyes. It helps improve vision, prevent macular degeneration, reduce eye problems such as eye fatigue and dry eyes.
3, Anti-inflammatory action:
Lutein has anti-inflammatory properties that reduce chronic inflammation and support a healthy immune system. For example, a study in older adults found that taking a nutritional supplement containing lutein reduced levels of C-reactive protein (CRP), a commonly used marker of inflammation. This also has a positive effect on reducing inflammatory symptoms in other parts of the body, such as arthritis, cardiovascular disease, etc.
4. Cardiovascular protection:
Lutein has antioxidant and anti-inflammatory effects that help reduce the risk of cardiovascular disease. It can reduce the inflammatory response in the blood and the abnormal endothelial function and thrombosis caused by oxidative stress, which helps to maintain the health of blood vessels and prevent the occurrence of diseases such as arteriosclerosis and heart disease.
5. Anti-cancer effect:
Regarding the anti-cancer effects of lutein, the current scientific research is not sufficient, and there is not enough evidence to prove that lutein can directly treat cancer. However, some studies have shown that lutein has anti-cancer potential. It can help neutralize free radicals and reduce the risk of DNA damage and cell mutations, thereby inhibiting the development of tumors.
Lutein is mainly found in foods such as green leafy vegetables, citrus fruits, corn, egg yolks, etc. Among them, spinach, kale, broccoli, citrus fruits, corn, etc. are all excellent sources of lutein.
Lutein, as an important nutrient, plays an important role in maintaining eye health and good health. Its antioxidant, vision-protective, anti-inflammatory, cardioprotective, and anticancer effects have made it a lot of attention. By eating more lutein-rich foods, choosing fresh ingredients, and eating egg yolks in moderation, we can increase our lutein intake so that we can better enjoy the benefits of lutein.
