Lutein is a nutrient necessary for the macula of the retina. Appropriate supplementation of lutein plays an auxiliary therapeutic role for people with damage to the macula or fundus.
Lutein supplement also helps to protect vision and prevent vision degeneration and macular degeneration.
The daily requirement for lutein for adults is 6 to 10 mg, so the body's demand for lutein can be met through food supplements. Generally speaking, lutein is higher in dark green, yellow, and orange vegetables, such as spinach and cabbage. Some fruits are also rich in lutein, such as mangoes, grapes, oranges, etc.
Supplementary health products: If your diet is unbalanced due to picky eating, allergies, etc., you can take lutein supplements appropriately, but you must pay attention to the dosage.
The American Optical Society recommends that the human body needs to consume 10 mg of lutein and 2 mg of zeaxanthin every day.
The "Dietary Nutrient Reference Intake for Chinese Residents (2013)" also recommends: 10 mg of lutein every day.
Do lutein supplements help eyes?
It varies from person to person.
1. For Myopia, dry eyes and visual fatigue groups:
The incidence of myopia is high now. Existing evidence shows that for myopic people, supplementing lutein has no effect on preventing and controlling myopia. Compared with lutein, vitamins AD and B1 are more conducive to the development of the eyeball.
2. For Middle-aged and elderly people:
Aging occurs in the eyes at the age of 40 to 50. The outer layer of fat in the macula is particularly susceptible to oxidative damage from sunlight, so this area is very prone to degeneration. Lutein has the effect of controlling macular degeneration.
3. Other people
Some studies suggest that for people with a family history of fundus disease, proper supplementation of lutein does have a preventive effect.
Supplements for Vision and Healthy Eyes
Another eye-protecting ingredient, bilberry anthocyanins, is also becoming increasingly popular. Billberry anthocyanins can improve the antioxidant capacity of the retina, strengthen the elasticity of eye microvessels, promote blood circulation, maintain normal eye pressure, ensure eye nutrition supply, and play a supporting role in visual fatigue and night vision. Anthocyanins are water-soluble natural pigments that can be directly absorbed by the human body. Studies have shown that anthocyanins can be detected in the blood 20 minutes after taking them, with a high absorption rate.
There are significant differences in the composition and content of anthocyanins between bilberry and blueberry. The types of anthocyanins in bilberry are more than those in blueberry, and the anthocyanin content in bilberry is up to 4 times that of blueberry.
