Lutein is the most important nutrient in the human retina. It is found in the macula and lens of the eye, with especially high concentrations in the macula. Our bodies cannot synthesize it on their own; we need to ingest and absorb lutein powder from external sources. Lutein powder can decompose and filter out ultraviolet rays and blue light from sunlight, preventing these high-energy rays from damaging the eyes. Therefore, supplementing with lutein powder can help our eyes resist external damage.
As a member of the carotenoid family, lutein is an important antioxidant, often referred to as "plant lutein." In nature, it coexists with zeaxanthin. Scientific research shows that lutein is the only type of carotenoid supplement found in the retina and lens of the eye. Since the human body cannot produce this element, it must be supplemented from external sources. If this element is lacking, the eyes may become blind.
Lutein Tntake Channels
Lutein powder is a precious nutrient widely found in nature, often appearing with zeaxanthin. It is abundant in orange-yellow fruits and vegetables such as papaya, pumpkin, citrus, goji berries, and peaches, providing a rich and colorful array. However, what is most surprising is that lutein is even more abundant in green leafy vegetables such as kale, spinach, leeks, bok choy, celery leaves, and cilantro, which are not only delicious but also highly nutritious.
Lutein is a type of fat-soluble vitamin with an absorption spectrum close to blue-violet light, helping the retina resist ultraviolet light. For the eyes, lutein powder is an important antioxidant that plays a significant role. Supplementing the human body with a large amount of lutein helps to maintain long-term vision, improve visual reaction time, and reduce visual damage.
Oxygen free radicals in the body are a major cause of many age-related diseases. Lutein has strong antioxidant capabilities and can inhibit the activity of oxygen free radicals, preventing them from damaging normal cells.
Lutein has distinct biological effects in inhibiting tumor growth, primarily through its antioxidant activity, inhibition of tumor angiogenesis, and cell proliferation.
Recent research findings have discovered that lutein can slow the development of early atherosclerosis. Animal experiments have shown that mixing lutein in the diet of mice and feeding it to them results in a lower incidence of arterial thrombosis compared to those not fed with lutein-containing food.
Lutein can serve as an effective adjuvant to enhance the blood sugar-lowering function of insulin. Therefore, consuming foods rich in lutein, such as fruits and vegetables, can reduce the risk of diabetes.
With aging and other factors, the UV protection barrier in the eye gradually decreases, allowing ultraviolet light to penetrate deeply, which changes the nature of eye proteins. The degenerative waste cannot be expelled from the eye and continues to accumulate, forming eye debris. This accumulation of eye debris is the common root cause of many eye diseases such as cataracts, glaucoma, vitreous opacity, and macular degeneration. Currently, ingesting lutein powder is an effective way to prevent and treat eye diseases.
