The role and correct choice of lutein

Food Business Network News has since ancient times been known chrysanthemums Liver eyesight effect, and clinical research through discovery, play the role of eyesight are lutein ingredient which contains the chrysanthemum, natural yellow leaf medical experiments proved that the plant contained It is an excellent antioxidant. Lutein is the main pigment in the macular area of the human eye. Lutein can prevent and regulate various eye diseases such as macular degeneration, optic atrophy, floaters, diabetes. Retinopathy, vision loss and blindness caused by senile eyeball macular degeneration. It also prevents cell aging and body organ aging.

Lutein is a natural substance widely found in vegetables, flowers, fruits and other plants. It is a kind of carotenoid and is the main pigment that constitutes the macular area of the human eye. Lutein has an important protective effect on the macula in the retina and is a key nutrient element to help the development of the eye. Moreover, the human body cannot synthesize through its own synthesis and must be supplemented by the intake of lutein. If the eye is deficient in lutein, it may cause macular degeneration and blurred vision, and then symptoms such as vision deterioration, myopia, and retinopathy may occur, and severe blindness may occur.

The role of lutein

One of the functions of lutein:

Protects the eyes from light damage, delays eye aging and prevents lesions: UV rays and blue light entering the eyes can cause a lot of free radicals, leading to cataracts and macular degeneration. Ultraviolet light can generally be filtered by the cornea and lens, but blue light can penetrate the eyeball directly to the retina and the macula. The lutein in the macula can filter out the blue light and avoid the damage of the blue light to the eye.

The role of lutein:

Protecting vision: Lutein acts as an antioxidant and photoprotective agent to promote the regeneration of rhodopsin in retinal cells, prevent high myopia and retinal detachment, and improve vision and vision.

The role of lutein:

Relieve visual fatigue: Lutein can quickly relieve visual fatigue and improve symptoms such as blurred vision, dry eyes, eye swelling, eye pain and photophobia.

The role of lutein:
Improve macular pigment density: protect the macula and promote macular development.

The role of lutein:

Prevention of macular degeneration and retinitis pigmentosa; reduce the production of drusen and prevent the occurrence of AMD (aging macular degeneration); anti-oxidation, help prevent cardiovascular cirrhosis, coronary heart disease and tumor disease caused by aging.

Lutein selection

Why is it recommended to choose lutein ester as a raw material (focus: whether to choose "lutein" or "lutein ester" for the human body)

It has been found that lutein itself has less light and heat stability and tolerance to human body pH than lutein ester. In the process of storage and human body administration, lutein bioavailability is caused by the above factors. The degree is low, and in the natural world, lutein is basically in the form of esterification. Whether it can directly use lutein ester to supplement the human body is another new research topic for carrot biologists.

In recent years, carotenoid biologists have explored the research on the stability of lutein ester and lutein, the hydrolysis of lutein ester in the process of digestion and absorption in vivo, and the comparative study on the biosynthesis of lutein monomer and ester. A comparative study on the bioavailability of lutein esters and monomers. In the study of lutein ester bioavailability, biologists used the concept of biological progress to describe the bioavailability of these two compounds before they were absorbed from the entrance to the intestinal wall cells. The specific experimental method was to determine the excretion rate of the two in rat feces. The excretion rate was defined as: excretion rate = excretion / gavage volume. The amount of gavage included: gavage amount = excretion + during digestion and absorption The amount of loss + the amount absorbed by the intestinal cells. Biological progress = (loss in digestion and absorption + amount absorbed by intestinal cells) / oral dose (gastric volume) excretion rate is considered to describe and compare lutein monomer and lutein ester biologic progress The parameters, through the scientific experimental process, finally found that lutein ester can not only be naturally hydrolyzed into free lutein in the human body, and the bioavailability of lutein crystals is 61.6% higher. In this regard, the use of lutein has begun a new change, the latest lutein products have chosen to use "lutein ester" as a functional raw material.

May 26, 2008 (Ministry of Health Announcement No. 12 of 2008) Document: The Ministry of Health of the People's Republic of China has established the approval of “lutein ester” as a raw material for new resource foods. Around 2010, it is a large production watershed of “lutein” products and “lutein ester” products.

The difference and efficacy of lutein and lutein ester

Lutein ester is a compound of lutein and one or two molecules of fatty acid. It is found in our daily diet like dietary fat, vitamin A and vitamin E. It and leaves Like flavin, it is a nutrient that naturally exists in nature. Lutein ester is extracted from marigold flower: it can be naturally hydrolyzed into lutein in human body, and it has the same protection effect as lutein to protect eyesight, relieve visual fatigue, prevent age-related macular degeneration, cataract and other diseases. And other anti-aging effects.

Precautions

The Ministry of Health has approved lutein ester as a new resource functional food, which can be widely used in the food and medicine fields, and the daily dosage is at least 12 mg (the grain lutein ester tablets are 12 mg per tablet).

Lutein products are used to regulate eye diseases, generally need to be taken for a long time, so it is recommended not to choose capsule products. Although the country has strict regulations on the heavy metal content of capsule shells, long-term use will cause harm to the body. There are the latest preparation methods such as tableting candy preparations.

Selective intake of lutein from fruits and vegetables, those fruits and vegetables contain more lutein ingredients:

Sources of lutein ester: spinach, lettuce, green broccoli, kale, celery, okra, egg yolk, carrot, corn, pumpkin, papaya, melon, guava, orange, orange, peach, etc. Zeaxanthin is derived from corn, egg yolk, orange, papaya, yellow pepper, and alfalfa.

Instructions for the selection of lutein products:

Lutein ester can be naturally hydrolyzed into free lutein when it enters the human body, and free lutein is used to supplement the eye body to exert its effectiveness. The latest scientific research reveals that because the properties of “lutein ester” are better than “lutein”, the Ministry of Health has approved lutein ester as a new resource food.

Recommendations for the efficacy of lutein products:

It is recommended to select “the product approved by the state-approved new resource functional food “Lutein ester” as the raw material of efficacy”. The advantages of lutein ester products are as follows:

1. Lutein ester light and thermal stability is stronger than lutein, ensuring the product labeling content, no reduction in the titer before the inlet, no loss.

2. Lutein ester acid tolerance is stronger than lutein, which is free from consumption and loss during passage through the stomach during ingestion.

3. In the small intestine absorption process, lutein ester bioavailability was higher than lutein 61.6%. The utilization rate is higher, and the waste is not fully supplemented.

Recommendations for the formulation of lutein preparations:

It is recommended to choose a lutein product produced by tableting candy preparation to avoid harmful addition. It is especially suitable for children and pregnant women who have high requirements for product safety.

Other varieties of lutein products: basically in the form of capsule or soft capsule preparation, although the country has strict requirements on the heavy metal content of the capsule shell, but ultimately it still contains heavy metals. Moreover, the quality of capsule shells used by some merchants violates national regulations.
