Overview

Lutein is a natural carotenoid that belongs to photosynthetic pigments and is the main pigment in the macular area of the human retina. It mainly exists in green leafy vegetables, with generally greener leaves and higher lutein content, such as mustard greens, green cauliflower, spinach, asparagus, green lettuce, etc. In recent years, with the popularization of health knowledge, more and more people know that lutein is beneficial for protecting the eyes. But do you really understand the effects and functions of lutein?

Uses & Effectiveness ?

The efficacy and effects of lutein on the eyes
1、 Main pigments that make up the retina
Lutein is the main pigment that constitutes the retina and macula of the human eye. Its content is relatively high in the human eye, and the body cannot synthesize it automatically. It must be ingested from the outside world. If it is severely lacking, it may cause blindness.
2、 Protect eyes from light damage
1. Resist blue light
Ultraviolet and blue light from sunlight entering the eyes can generate a large amount of free radicals, leading to cataracts, macular degeneration, and even acne. Ultraviolet rays can generally be filtered out by the cornea and lens of the eye, but blue light can penetrate the eyeball directly to the retina and macula. Lutein in the macula can filter out blue light, avoiding damage to the eyes caused by blue light. The large amount of blue light emitted by electronic product screens now can also bring a huge burden to the eyes. If the consumed lutein is not replenished in a timely manner, it can cause eye diseases such as retinopathy, cataracts, and severe myopia.
2. Delaying eye aging and preventing lesions
The outer layer of fat in the macular area is particularly susceptible to oxidative damage from sunlight, making it prone to degeneration. Lutein can provide protection, delaying eye aging and preventing disease.
3、 Protecting eyesight
1. Promote the regeneration of rhodopsin
Lutein, as an antioxidant, has a photoprotective effect, promoting the regeneration of rhodopsin in retinal cells, preventing severe myopia and retinal detachment, and improving and protecting vision. It is particularly suitable for students, drivers, and others to consume.
2. Prevent vision loss
The unique function of lutein is to prevent visual impairment and blindness caused by age-related macular degeneration.

The antioxidant effect and function of lutein
Eliminate free radicals
Lutein is an excellent antioxidant that can resist cell and organ damage caused by free radicals in the human body, thereby preventing cardiovascular sclerosis, coronary heart disease, and tumor diseases caused by aging. It can inhibit the activity of reactive oxygen species, prevent their damage to normal cells, and protect the body from harm.
Other functions and effects of lutein
1、 Delaying aging
Due to its antioxidant properties, it can effectively eliminate excess free radicals in the body, prevent free radical peroxidation, and thus play a role in delaying aging and beautifying the skin.
2、 Reduce the incidence of cataracts
Increasing the intake of lutein can reduce the incidence of cataracts.
3、 Delaying arteriosclerosis
Lutein has a delaying effect on the early progression of arteriosclerosis, mainly due to the relationship between changes in arterial intima thickness and lutein content in the blood.
4、 Anti-cancer effect
Lutein has unique biological effects in inhibiting tumor growth, mainly through antioxidant activity, inhibition of tumor angiogenesis and cell proliferation, and has inhibitory effects on various diseases such as breast, prostate, rectal, and skin acne.
5、 Promote eye development and brain health and intelligence enhancement
1. Beneficial for infant eye development
Lutein is an important component of the human retina, macular area, and crystalline lens, especially in infants. Consuming foods rich in lutein, such as cabbage, collard greens, spinach, etc., is beneficial for the development of infants' eyes.
2. The impact on brain development and cognitive abilities
Lutein not only accumulates in large amounts in the macular area of the eye, but also in areas of the brain that are important for learning and memory. It is not only beneficial for maintaining cognitive and language abilities in older adults, but may also be involved in the development of the nervous system in young children's brains.
6、 Coloring effect
Lutein is widely used in seasoning, tobacco, pastries, candies, and various feed processing industries. In China, lutein has been widely used as a coloring agent.
