¿Qué es exactamente la luteína?

Luteína, also known as “eye gold”, is the most important nutrient in the human retina. It is found in the macula (the center of vision) of the retina of the eye and in the lens, especially in the macula which contains a high concentration of lutein. Lutein is an important antioxidant, a member of the carotenoid family, also known as “plant lutein”.

It co-exists in nature with corn lutein and zeaxanthin. Scientific studies have shown that lutein is the only carotenoid found in the retina and lens of the eye, and this element is not manufactured by the body itself, and must be supplemented by external intake. In the absence of this element, the eye will go blind. The ultraviolet and blue light from sunlight entering the eyes can produce a large number of free radicals, which can lead to cataracts, macular degeneration, and even cancer.

Luteína can filter blue light, decompose strong light and ultraviolet damage to the human eye, so as to avoid blue light damage to the eyes, to prevent vision degradation and blindness caused by luteína loss, so lutein zeaxanthin is also known as the eye protection god.

The role of lutein supplement

1, the main pigment components of the retina: luteína and zeaxanthin constitute the main components of vegetable, fruit, flowers, and other plant pigments, and are also the main pigment of the macula area of the retina of the human eye. The human eye contains a high amount of luteína, an element that the human body cannot produce and must be supplemented by ingestion of lutein zeaxanthin supplement. Without this element, the eye will go blind.

2, protect the eyes from light damage, delay the aging of the eyes and prevent lesions: ultraviolet and blue light in the sun into the eyes will produce a large number of free radicals, leading to cataracts, macular degeneration, and even cancer. Ultraviolet light can generally fill the cornea and lens filter out, but blue light can penetrate the eye to the retina and macula, and lutein in macula can filter out blue light to avoid blue light damage to the eye. The fatty outer layer of the macula is particularly vulnerable to oxidative damage from sunlight, so this area is prone to degradation.

3, antioxidant, help prevent cardiovascular sclerosis caused by aging, coronary and tumor diseases.

4, vision protection: luteína for eyes as an antioxidant and photoprotective effect, can promote the regeneration of rhodopsin in retinal cells, can prevent severe myopia and retinal detachment, and can be used to improve vision and protect vision for myopia, amblyopia, strabismus, cataracts, keratoconjunctival xerosis, macular degeneration, retinal degeneration, etc. Especially suitable for students, drivers to eat.

5, relieve the symptoms of visual fatigue: blurred vision, dry eyes, eye distension, eye pain, photophobia.

6, improve macular pigment density, protect macular yellow, promote macular development.

7. Prevent macular degeneration and retinitis pigmentosa.

Luteína and zeaxanthin supplements prevents vision loss

With the growth of age, people’s vision gradually declines, and some people will show cataracts. People usually think that this is caused by the aging of the body. But the latest research suggests that vision loss is also related to vitamin deficiency in the body

Two reasons for vision loss

1. Temporary exposure to UV rays. The lens cells of the eye are primarily made of crystallized proteins. These proteins act like optical fibers that allow light to pass through and reach the retina to form vision. Ultraviolet light and any kind of visible light can pass through a transparent lens. The lens is temporarily exposed to ultraviolet radiation, which will damage the lipid, protein and other components. The accumulation of damaged proteins will gradually change from bright to cloudy, forming cataracts and damaging vision.

2. Vitamin deficiency. Inside the lens, there are high concentrations of the antioxidants vitamin C and vitamin E, as well as small amounts of the carotenoids lutein and zeaxanthin. They are useful for blocking UV and free radical damage. According to experts at the U.S. Department of Agriculture’s Center for Nutrition Research in the Elderly, the more damaged proteins in the lens, the fewer proteases and antioxidants that play a role in maintenance, the more likely the lens is to show cataracts and macular degeneration.

Diet can stop vision loss

In 2001, in order to understand the relationship between the opacity of the lens nucleus and nutrient uptake, 478 women aged 53 to 73 years without diabetes and cataracts were followed for 13 to 15 years. Results showed that women with adequate nutrient intake were less likely to develop cataracts than those with the lowest intakes of vitamins C, E, riboflavin, folate, fuscosin, beta-carotene, lutein, and zeaxanthin. Women who took vitamin C for more than 10 years were 64 percent less likely to develop cataracts than women who never took vitamin C.

best lutein and zeaxanthin supplements and falconine play an important role in preventing cataracts even though they are present in low concentrations in the lens. Lutein and zeaxanthin are reported to be the highest in spinach, kale and broccoli, and the highest in cooked tomatoes.

Stopping macular degeneration At the center of the retina, there is a 3 mm diameter macula. It is a visual tissue that plays a key role in the eye. The breakdown of these light-sensitive cells is a factor in age-related macular degeneration. Age-related macular degeneration is an important cause of vision loss and blindness in the elderly. According to the report of the National Institute of Ophthalmology of the United States, it has been proved that the blue light with high energy in the sun has the strongest effect on retinal damage, and lutein and zeaxanthin in the macula can absorb blue light and remove the free base, so it has the role of maintaining the retina.

After entering old age, due to temporary light damage, the demand for these two pigments in the eyes has gradually increased. Lutein is about 6 to 7 times the amount required for zeaxanthin. When blood circulates to the macula, the two pigments enter the center of gravity from the outer layer of the macula and stay there. It was found that the concentration of lutein and zeaxanthin in the eyes of macular degeneration patients was lower than that of those without macular degeneration. It is explained that lutein and zeaxanthin have maintenance effect on macula.

Researchers at the University of Manchester in the United States divided people with macular degeneration into two groups and asked them to take a 15% natural lutein formulation daily for 18 weeks. After 12 weeks, macular pigment concentrations increased in both groups. People who already had macular degeneration in one eye responded equally well to lutein supplementation in both eyes. This makes it possible to use lutein and zeaxanthin to never delay or prevent the progression of macular degeneration.

Eat more tomatoes and dark green vegetables

At present, the Expert Committee on Food Additive Binding of the Food and Agriculture Organization and the World Health Organization has determined that the tolerable daily intake of lutein and zeaxanthin for a person is 2 mg/kg of body weight. For example, a person weighing 70 kg should consume 140 mg of lutein and zeaxanthin daily. centrovision lutein 15 mg，This new norm will be published in an official document of the Food and Agriculture Organization of the associated countries and the World Health Organization.

Dark green vegetables and yellow fruits are important food sources of lutein and zeaxanthin. Cooked kale contains 15.8 mg per 100 grams and cooked spinach contains 7.1 mg per 100 grams, which are the two vegetables with the most lutein vitamin. Also high in lutein omega 3 are romaine lettuce, broccoli, corn, green peas, cabbage and egg yolks.

Even if supplementation does not restore vision that has already been lost, it can help patients in the middle and early stages maintain the remaining vision. Therefore, for people of different ages, eating more tomatoes and dark green vegetables has a maintenance effect on the maintenance of vision.
