The development of the brain is achieved through neuronal connections. If you want the brain to generate more connections, you need to use high-quality fats such as DHA to create appropriate locks on the nerve cell membranes and help the key of neurotransmitters to be inserted smoothly. . To put it bluntly, DHA can help us generate brain connections and make brain messengers run faster and more efficiently. It turns out that mathematical thinking can be played in this way. Multi-level collection [8 volumes in total] epub. The reason why highways can go anywhere quickly and freely is because there is a transportation network that extends in all directions. The reason why some children are quick in thinking and can draw inferences from one instance is because their brains Neural networks are developed. The size of a child\’s brain reaches 80% of that of an adult at the age of 3, and reaches 90% by the age of 6. The infant period is the golden period for building a smart brain. If you also want your child\’s brain to be as developed as a highway, then Let him take in enough DHA. When it comes to foods that contain a lot of DHA, it has to be fish. The fiber structure of fish is relatively short, making it easier to digest and absorb than other meats. This is very friendly to children whose digestive systems have not yet matured. So which fish have higher DHA content? Each bite of the six types of fish introduced below is full of DHA, and they are at the lower end of the food chain. Their mercury content is relatively low, making them safer to eat. The first is rainbow trout. Although it is a freshwater fish, it contains 550 mg of DHA per 100 grams of fish meat. Although trout looks similar to salmon, experienced people can tell it apart at a glance. Looking at the whole fish, rainbow trout has a pink line, and salmon does not. If it is a fish fillet, it is easy to distinguish the two when put together. The flesh of trout is redder, while the flesh of salmon is shallower and has clear lines. But if the fish fillets are placed alone and you are a novice, it will be difficult to tell the difference. The second type is sardines, which are very nutritious and contain a large amount of DHA, EPA, Omega-3, etc., of which DHA contains 870 mg per 100 grams. However, it has many small thorns and is more troublesome to handle. It is not recommended for children who are too young to eat it. After your baby starts to add complementary foods, it is recommended to eat fish that are high in protein, low in fat and have few bones, such as snapper, halibut, and salmon. The third type is eel, which is rich in vitamin B and vitamins A, E and D, and DHA reaches 1300 mg per 100 grams. However, it has more thorns and a lot of fat. You can choose according to your own needs. The fourth type is salmon, which has the same DHA content as eel, both containing 1,300 mg in 100 grams.

Although the two fish have similar nutrition, their prices are different. And if you buy stale salmon, you will easily get diarrhea. Generally, salmon with good meat is bright orange, and the white lines are clear and shiny. The fifth type is yellowtail amberjack, which contains 1700 mg of DHA and 940 mg of EPA per 100 grams of fish meat.. There are almost no spines and you can eat them directly without removing the bones. However, they are generally imported and can only be purchased frozen. The sixth type is mackerel, also known as mackerel, which has high contents of EPA and DHA, of which the DHA content is as high as 3100 mg. Both of them can well promote the flow of blood and the transmission of information to the brain. If you can\’t buy fresh ones, you can buy canned mackerel. It is recommended to eat it with dark green vegetables. This can reduce the oxidation of EPA and DHA and is more conducive to the absorption of nutrients. Of course, eating more fish is not always better. We can adjust the portion according to the age of the child. For babies aged 1-3 years old, 2 servings per week is enough, for babies aged 4-6 years old, 3 servings per week, and for pregnant women, 7-9 servings per week. One serving is about the size and thickness of 3 fingers put together.
