Impaired vision – real scourge of modernity. This problem affects not only the elderly, but also young people. The reason for this is the computer and other gadgets that have tightly burst into our lives. Also, the quality of vision is affected by unfavorable ecology and lack of vitamins and minerals in the diet. Lutein deficiency is especially observed. This yellow pigment from the group of carotenoids is not produced in the human body. It comes only with foods and vitamin supplements. The online publication estet-portal.com will tell you what the use of lutein gives us and how it can be obtained.
Why lutein is so important for eye health
Once in the body, these substances accumulate in the tissues. Its highest concentration is in the center of the retina. This area is responsible for high-quality and clear vision. Scientists have discovered that the pigment absorbs ultraviolet radiation, thereby reducing the harmful effects of sunlight on the retina eyes and allowing us to see the world around us clearly, in great detail. In addition, lutein is an antioxidant that neutralizes free radicals. These are molecules formed as a result of exposure to light, poor ecology, tobacco smoke, certain drugs and other factors. They also destroy cells and tissues, accelerating the aging process.
Clinical studies have found that lutein deficiency provokes destructive changes in the tissues of the eye. And, as a result, vision deteriorates, and irreversibly.
The use of lutein is as relevant as ever. After all, the ozone layer has decreased, and the amount of ultraviolet rays has increased. In addition, the world is experiencing computerization. The pigment not only protects the retina from age-related and other damage, but also improves vision, and also prevents the appearance of cataracts, other eye diseases, and even blindness.
Main sources of lutein: vegetables and fruits
In order to obtain a sufficient amount of this biologically active substance, certain foods must be consumed. The pigment can be obtained from food of plant origin. Especially a lot of it in vegetables and fruits of yellow-red color, as well as in dark leafy products. These are:
• carrots;
• spinach;
• pumpkin;
• sweet corn;
• green peas;
• celery;
• kale;
• broccoli;
• brussels sprouts;
• parsley;
• avocado;
• persimmon;
• peach;
• tangerine;
• orange;
• black grapes.

Lutein is also found in animal products – egg yolk. The use of lutein is very important for modern man. Therefore, it is imperative to include more fruits and vegetables in your diet. If some of them are out of season now, they can be replaced with special
nutritional supplementsthat contain this active substance. Most of these drugs are natural based, so you don't have to worry about side effects. Vitamin supplements are available in almost any pharmacy.
This substance is necessary for every person, regardless of age. But young children especially need it. Indeed, immediately after birth, a powerful stream of daylight enters the eyes of a newborn, and with insufficient natural protection, the retina begins to be damaged.
Of course, lutein is present in mother's milk. Therefore, breastfeeding helps protect the baby from danger. But if the baby is fed with artificial mixtures in which there is practically no pigment, the risk of visual impairment increases. Luckily, baby food manufacturers have begun making products fortified with lutein. By its properties, it is close to breast milk. To maintain the protection and health of the eyes, it will be enough to consume the pigment at a dosage of 100 mcg / l.
The use of lutein is also very necessary for older people who have age-related macular degeneration, leading to vision loss. This substance will also be useful for those who suffer from cataracts. In these cases, in addition to the usual products containing lutein, it is necessary to use special drugs, the dosage and regimen of which are prescribed by the attending physician.
Special supplements should be taken as a preventive measure for diseases such as cancer, stroke, arthritis. Indeed, in such cases, the concentration of pigment in the human body decreases.
