DHA plays a very important role in the brain development of the baby. Therefore, mothers may wish to eat more foods rich in DHA. After the baby is born, it is also necessary to supplement DHA. When is the critical period of baby brain development? ◠The baby’s brain has been formed during the fetal period The baby has already had the basic structure of the cerebral cortex at birth, but the cortex is still shallow, incompletely differentiated, and development is not perfect. At the same time, the nerve cells of the baby's brain are characterized by "one-off completion." At birth, they have nearly 130 to 18 billion nerve cells, but no intricate interweaving of brain regions has yet been formed. ◠The brain’s weight at birth is equivalent to 25% of the brain weight of an adult When the baby was born, the weight of the brain was 350-400 grams, which is equivalent to 25% of the brain weight of an adult. At the age of 6 months, the weight of the brain is 600-700 grams, which is equivalent to 50% of the brain weight of an adult. The brain weight at the age of 1 is 800 grams, equivalent to 60% of the brain weight of an adult; the weight of the baby's brain at the age of 2 years is 900 to 1000 grams, which is equivalent to 75% of the weight of the adult brain. ◠The critical period of baby brain development is 0-3 years old With the increase of the baby's age, plus the benign stimulation in the environment, the baby's brain development will gradually mature. This process is completed within approximately 1 year of the baby's age. At age 6, it is basically equivalent to an adult. Therefore, the critical period of baby brain development is 0 to 3 years old, but it is even more critical within 1 year of age. It is a period of rapid development of the baby's brain and is also the period when the baby's brain is most plastic. Rapid brain development requires adequate nutrition, especially DHA support. The formation and development of brain cells and the efficient connection between neural networks are all dependent on DHA. As a very important brain nutrient, DHA accounts for 35% to 40% of total brain fat, and is known as "brain gold." A number of studies have shown that scientifically adequate intake of DHA can, on the one hand, promote the formation of more connections between brain cells, promote the growth and development of various areas of the brain, make the brain more dense neural network, and promote the improvement of brain structure and function; On the other hand, it helps to transmit information more quickly and smoothly, thereby improving brain function, enhancing memory and comprehension, and effectively enhancing intelligence. If DHA is lacking, it will cause leakage or reduction of information, and it will not be able to conduct well. Brain cell connections cannot be formed. American nutrition expert Bates has done an experiment and used a method of scanning brain waves to do clinical research on two groups of infants. The experiment and follow-up study found that infants who had high levels of DHA supplemented during infancy had a 7-point higher intelligence development index at 18 months than those without DHA and a 7-point lead at age 4. The study of another nutritionist, Austin, confirmed from the opposite perspective: Infant supplementation with low levels of DHA, Intelligence Development Index (MDI) at 12 months, and IQ score at 3 1/4 years old, and not There is no significant difference in the baby who supplements DHA. Obviously, a high level of DHA intake during infancy can provide sufficient nutritional basis for brain development, and it can help the baby's intellectual development and window period's ability to continue to lead. In short, in the baby's "window period" to ensure adequate nutrition, timely targeted early education; to stimulate the baby's brain to develop better, the baby's intelligence and ability will be fully developed. The three major roles of DHA In the process of children's growth and development, DHA plays an important role and plays at least three major roles: Role 1: Brains and spirits. The British professor of brain nutrition first discovered that Japanese children who eat fish often have higher IQs than European and American children who often eat meat. This is mainly due to the abundance of DHA in fish. DHA is effective in promoting the development of brain cells, stimulating the extension of brain nerve fibers, increasing brain volume, and enhancing brain acuity. Research data also show that children who have been supplemented with DHA within 4 months after birth have an advantage in their mental development until 4 years old. Role 2: Eye-catching taste. DHA penetrates deep into the retina through blood circulation, keeps the retinal cells soft, stimulates photoreceptor cells, and rapidly transmits external information received by the eyes to the brain, thereby enhancing visual function and enabling the child to see more and more clearly. Role 3: Disease buster. DHA can lower blood lipids, prevent thrombosis, and also has a certain anti-inflammatory effect. For children, DHA has 6 sources: 1. Breast milk. The content of DHA in colostrum is particularly rich. However, the content of DHA in mother's milk depends on the food structure of three meals. Japan’s mothers eat more fish, with a DHA content of 22% in milk, ranking first in the world; followed by Australia, about 10%; and the United States, with a minimum of 7%. 2. Formula milk powder. Refers to the addition of DHA formula milk powder. 3. Fish. Fish with a high DHA content include salmon, mackerel, mackerel, mackerel, sardines, horse mackerel, swordfish, tuna, yellow croaker, Pacific saury, squid, octopus, and flower bonito, per 100 g of fish. DHA content up to 1000 mg or more. For a certain type of fish, the high content of DHA is also the first to promote orbital fat, followed by fish oil. 4. Dried fruits. Such as walnuts, almonds, peanuts, sesame and so on. The alpha-linolenic acid contained therein can be converted into DHA in the human body. 5. Algae. 6. DHA products. There are two kinds on the market: one is from deep-sea fish oil and the other is from algae. The former is derived from fish fat, but there are at least 3 major defects: (1) The content of EPA (eicosapentaenoic acid) in fish oil is too high, which can make the proportion of DHA too low, which is a big difference from breast milk. In line with the child's physiological needs; (2) Although the DHA content in fish oil is relatively high, but does not contain an important unsaturated fatty acid for brain development - AA (arachidonic acid), and excessive EPA will also Inhibit the formation of AA in the child's body; (3) The fish is contaminated with mercury, lead, or other heavy metals or arsenic and other harmful substances in varying degrees, and the safety is low. In contrast, the advantages of algae are outstanding. They are characterized by high DHA content, low EPA content, and direct extraction from the sea. They do not contain pigments, have high safety and strong antioxidant capacity, and are most beneficial to infants and young children. Therefore, pregnant women and children should prefer algae DHA products. Measures to allow children to achieve DHA compliance During the third trimester of pregnancy, especially in the third trimester, pregnant women should eat more foods rich in DHA, such as fish, dried fruits, algae, etc., and if necessary, they can take DHA products or add pregnant women's milk powder containing DHA to ensure the fetus. There is enough reserve while preparing for feeding. Breastfeeding is preferred after the child is born, especially if you do not miss colostrum. If breast milk is insufficient or cannot be breastfed, it can be supplemented or replaced with formula supplemented with DHA. After the child is weaned, three meals should be arranged in accordance with the principle of balanced diet, and the fish should be properly leaned and reasonable cooking methods should be adopted (preferably steamed or roasted to avoid deep frying to reduce the loss of DHA). In general, children who breastfeed (especially the mother often eat fish, dried fruits and algae food), timely add food supplements such as fish paste, tofu, etc., in line with the principles of variety, balanced nutrition, DHA intake can meet standards, No need to add extra. If you fall into the following situations, it is very likely that DHA intake is not enough and you need to make up for it in other ways: 1. The fetus begins to accumulate DHA in its own brain from the second trimester (26 weeks of gestation) and accumulates the fastest during the second trimester. Premature babies are born early, shortening the time to accumulate DHA, so the amount of DHA in the brain of preterm children is far lower than that of full-term babies. Especially those with a birth weight of less than 1500 g, the lack of essential fatty acids is even more serious. Supplementing DHA for a long period of time can improve the fatty acid nutritional status, visual function, and learning ability, and it can significantly promote growth and development. 2. Breast-feeding children, if limited to seasonal, geographic, or economic conditions, the type of food the mother is eating is relatively single and the DHA content in breastmilk is too low, there is also the need for additional supplements. 3. Children who are fed formula should have additional supplements if they choose DHA-free formula. If they choose a formula with low DHA content, they should also supplement it in small quantities to make up for the deficiency of DHA. 4. At the stage of adding supplementary food, if the child is allergic to fish food, it should also supplement DHA by other means. 5. Although supplemental foods are added, children under 2 years of age have limited stomach capacity and need to consume more nutrients. Consider supplementing DHA in small doses. In addition, in order to achieve the desired effect, don't neglect the supply of other brain nutrients. The brain needs multiple nutrients. In addition to DHA, AA is also important and constitutes another important fatty acid in the brain, accounting for about 15% of total brain fatty acids. Therefore, while supplementing DHA, we cannot ignore the supply of AA and keep it at the optimal ratio of 1..2. It is recommended that when parents purchase formula milk powder, they must be sure to see the amount of ingredients on the packaging, and brands that meet or approach this ratio are better. At the same time, DHA and lutein are a pair of “golden partners†for retinal development, and lutein plays a protective role for DHA, and both have the same effect as supplemental energy.
