Lutein invisible sunglasses for children

Abstract: as early as 2000 years ago, the concept of “five fruits as help” and “five dishes as filling” was put forward in China’s medical works. Why are vegetables and fruits so important to human health?, Professor He Zhiqian, a leading Chinese nutritionist, said that as a relatively advanced phytochemical, lutein is a key nutrient element to help eye development. It has the functions of filtering blue light and antioxidation. It is an “invisible Sunglasses” for infants and young children., The discovery of phytochemicals has put forward the dietary concept of “five fruits as help” and “five dishes as filling” in China’s medical works more than 2000 years ago. Why are vegetables and fruits so important to human health? And people have to constantly find new nutrients in fruits and vegetables?, He Zhiqian, Professor of nutrition at Sun Yat sen University and honorary director of China Nutrition Society, helped us solve the mystery. He said that the history of human development suggests that we need to constantly understand new things. In the past, people only realized that fruits and vegetables contained a variety of vitamins, such as vitamin C, which was discovered in ocean exploration. Before that, thousands of sailors lost their lives because of ignorance. Today’s research on phytochemicals is also similar to the history of the discovery of vitamins. Phytochemicals refer to a large class of substances with certain physiological functions extracted from plants. Thousands of them are being discovered and studied constantly., Lutein is one of phytochemicals. It was found in the study of blindness in the elderly., He Zhiqian, the guardian of retinal health, said that as a more advanced phytochemical, the importance of lutein has been affirmed in the global nutrition community; The reason why the macula of human eyes is yellow is that it is full of lutein and its homologues. Lutein filters blue light and antioxidants. It is a key nutrient element to help eye development. Therefore, some people also compare lutein to “invisible Sunglasses”., Blue light is 400-500 nm high-energy light (an invisible blue wave in sunlight), and excess can cause retinal damage. Especially for infants and young children. Because the baby’s lens is relatively clear at birth, about 70-80% of the blue light can penetrate the lens to reach the retina at the age of 0-2, and about 60-70% of the blue light will irradiate the retina at the age of 2-10. At the same time, the baby’s retina is full of tiny blood vessels to deliver more oxygen to meet the needs of development, which also increases the number of oxygen free radicals with attack and destruction. DHA, an important substance promoting retinal development, is easy to be oxidized.,

Professor He Zhiqian, a leading Chinese nutritionist, said that as a front-end phytochemical, lutein is a key nutrient element to help eye development. It has the functions of filtering blue light and antioxidation. It is an “invisible Sunglasses” for infants and young children.

he Zhiqian, Professor of nutrition at Sun Yat sen University and honorary director of China Nutrition Society, helped us solve the mystery. He said that the history of human development suggests that we need to constantly understand new things. In the past, people only realized that fruits and vegetables contained a variety of vitamins, such as vitamin C, which was discovered in ocean exploration. Before that, thousands of sailors lost their lives because of ignorance. Today’s research on phytochemicals is also similar to the history of the discovery of vitamins in that year. Phytochemicals refer to a large class of substances with certain physiological functions extracted from plants. Thousands of them are constantly being discovered and studied.

lutein is one of phytochemicals. It was found in the study of blindness in the elderly.

he Zhiqian, retinal health guard

and

, said that as a relatively front-end phytochemical, the importance of lutein has been affirmed in the nutritional circles all over the world; The reason why the macula of human eyes is yellow is that it is full of lutein and its homologues. Lutein filters blue light and antioxidants. It is a key nutrient element to help eye development. Therefore, some people also compare lutein to “invisible Sunglasses”.

blue light are 400-500 nm high-energy light (an invisible blue wave in sunlight), and excess can cause retinal damage. Especially for infants and young children. Because the baby’s lens is relatively clear at birth, about 70-80% of the blue light can penetrate the lens to reach the retina at the age of 0-2, and about 60-70% of the blue light will irradiate the retina at the age of 2-10. At the same time, the baby’s retina is full of fine blood vessels to deliver more oxygen to meet the needs of development, which also increases the number of oxygen free radicals with attack and destruction. DHA, an important substance to promote retinal development, is easy to be oxidized.

he Zhiqian pointed out that, therefore, lutein plays a particularly important role in early life, especially from birth to 4 years old. It can effectively filter blue light, resist DHA oxidation and help protect the retina of infants and young children. So more absorption is needed.

where to find lutein

dark green, yellow and orange vegetables and egg yolks contain lutein, among which dark green vegetables such as spinach and cabbage are rich in lutein. However, due to the relative existence of various conditions, there are many ways to absorb enough lutein.

for babies, breast milk is the best food for babies at any time. He Zhiqian said that lutein is an ingredient in breast milk. Breast milk research in nine cities around the world found that each liter of breast milk contains an average of 25 micrograms of lutein.

if breast milk cannot be fed or breast milk is not enough, it is recommended to choose formula supplemented with lutein. He Zhiqian said that the study found that infants often ate insufficient vegetables. In the face of these babies, they can choose the formula supplemented with lutein to establish a more complete nutritional safety net for their babies. At the same time, Baobao is encouraged to eat more fruits and vegetables and supplement enough lutein from food to help their eyesEye health.

he Zhiqian pointed out that lutein is important, but not unique. Lutein, together with DHA / AA, taurine, vitamin A, natural carotene and other nutrients, can help the development of infants’ eyes and vision. They have different effects on the development of eyes: for example, DHA / AA mainly helps the development of vision and helps to improve visual acuity; Vitamin A is an essential nutrient for human visual development. It helps to convert light into visual nerve signals, improve the adaptation of retina to dark light and so on.
