Hello! About 6mg a day, supplemented with lutein intake, can improve the level of lutein in the human body, use lutein's excellent oxidation resistance, get rid of excessive free radicals in the body, restore the balance of oxidation-oxidation system, and keep yourself healthy and away from diseases. Lutein and human health (2) In a person's life, about 90% of the knowledge and information are obtained by eyes. The healthy growth of children is the expectation of every parent. In the face of intense studies and heavy homework, how to protect the eyeballs during the development period is the key to the success of children. At present, the incidence of amblyopia among children in China is close to 5%, and there are more than 20 million children with amblyopia. The incidence of myopia is close to 60%, ranking first in the world. The incidence of myopia among adolescents in China has risen from the fourth place in the world in 1998 to the second place in 1999. People's eyeball development period is at12-18 years old, and stops at about18-20 years old. This is the period when teenagers are eager for knowledge and study, and it is also the peak of myopia. However, the same students, why is the myopia rate in rural areas far lower than that in cities? In recent years, western nutritionists have finally uncovered this mystery through in-depth research. It turns out that the occurrence of myopia is closely related to the low intake of lutein. Rural children eat green vegetables directly from the ground every day, so their lutein intake is very sufficient. However, urban children usually eat high-protein and nutritious foods and rarely eat fresh green vegetables, so the lutein intake is much less than that of rural children. This is the main reason for the huge difference in vision between urban and rural children. In the past, people only paid attention to eye hygiene, but ignored eating habits and nutritional requirements. The eye is one of the most sensitive organs of the human body to radiation-induced free radical damage. Because of its special sensitivity to light, the eye generally contains high concentrations of antioxidants. In modern life, there are many radiation sources: sunlight, ultraviolet rays, televisions, computers, mobile phones, etc. These radiations cause very strong radiation damage to the eyes, produce free radicals, and destroy the lens and retina of the eyes. With the increase of age, this natural protection gradually weakens, and as a result, protein in the lens is oxidized by free radicals. Lutein can prevent blue light filtering.
