"Xiaoli's mother, why are your Xiaoli's grades so good?" Xiaoming 's mother visited Xiaoli's mother's house and saw many certificates posted on the wall.
Xiaoli's mother smiled and said, "Your Xiaoming is also a good child, and her grades are good."
Xiaoming's mother said, "I don't know if our Xiaoming has poor memory or why. It is very difficult to memorize texts in normal times, and he is not focused on when doing homework. Moreover, he is sick every few days, which makes me very big."
"I have no memory, difficulty memorizing texts, and poor health. You can try to supplement zinc for him." Xiaoli's mother said, "I heard from experts that some children have zinc deficiency in and are like this."
After hearing Xiaoli's mother's words, Xiaoming's mother immediately wanted to buy zinc supplement medicine online, but was stopped by Xiaoli's mother. She said: "Medical supplements are not as good as food supplements. My child is only 8 years old now. Just give him more foods rich in zinc nutrition . Unless it is very zinc deficiency, you need to take medicine to supplement zinc."
Xiao Ming's mother thought it makes sense, so she decided to let Xiao Ming eat more high-zinc food . However, she once again encountered a problem: she didn't know which foods contain more zinc element , and she didn't know what benefits it would be for the body. In fact, there are many mothers in real life, just like Xiao Ming's mother, who don't know what zinc is at all. Next, I will answer these questions one by one for you.
1. What is zinc? What are its functions?
zinc is one of the chemical elements of and is also the second most essential nutrient element in the human body after iron. It participates in homeostasis, immune response, oxidative pressure, cell transmission, apoptosis and aging .
In addition, zinc is also related to human DNA synthesis, RNA transcription, cell division and apoptosis . During a person's life, in infants, children and adolescents, due to physical development needs, the nutritional demand for zinc is very high.
Because zinc has a promoting effect on the growth and development of the human body, it can maintain normal appetite, enhance immunity, promote wounds and trauma healing, protect vision, maintain male sperm production function, affect and regulate brain cells, nerve functions, etc. Among many functions, zinc has the strongest effect on the brain, and it is called 's "source of brain power".
Research has found that zinc can regulate the brains of various mammals. It can maintain the functions of various enzymes and receptor , and at the same time, it can maintain the normal structure and function of nervous system . If zinc deficiency occurs during the growth and development period, it will cause dysfunction of DNA and protein in brain cells, causing abnormal intellectual development.
Zinc is so important to the human body, but around the world, there are about 20% of people with who have zinc deficiency. It is understood that the zinc level in a normal human body is about 70-250 ug/dl. If it is lower than 50-60 ug/dl, it belongs to mild and moderate zinc deficiency . If it is 50 ug/dl, it can be judged as severe zinc deficiency .
When the human body has malnutrition, the body will have a variety of symptoms according to the degree of zinc deficiency. For example, mild or moderate zinc deficiency can cause symptoms such as glossitis, loss of taste, delayed development, rough skin, slow wound healing, and mental depression. In addition, will also increase the incidence of decreased immunity, infection, oligospermia, hyperammonemia, , etc.
If the body is severely zinc deficiency, it may cause night vision loss, infection, drowsiness, hair loss, , memory loss, etc., and men will also experience hypogonadism . Zinc malnutrition can have a serious impact on health, especially on children's development.
For example, children are prone to anorexia, partial eating, and lack of hunger and fullness in the case of zinc deficiency. The nutrition of the body is not supplemented, which not only affects the development of height and weight, but also causes short and thin , but also causes brain dysplasia, affecting their memory and intelligence .
Children with zinc deficiency are more likely to catch a cold, fever, , oral ulcers, etc. This will not only endanger the health of children, but also affect brain development. Some children even experience abnormal phenomena such as biting their nails, eating their hair or soil. Therefore, parents should pay more attention to whether their children's body is zinc-deficient. If you want your child to develop well and be smarter, you should eat more foods rich in zinc .
2. If you want your child to be smarter, you often eat high-zinc foods.
1, sea fish meat
fish meat is a food with high protein and low fat , and is also one of the meat that people often eat. Among them, sea fish is rich in nutrients such as DHA, protein, lecithin , zinc, vitamin , etc. These nutrients can supplement the nutrients required for brain cell development, prevent brain cell degeneration, enhance brain memory function, and to a certain extent, prevent brain aging.
During the growth and development of children, parents can insist on giving their children some fish meat such as steamed bass , braised fish , crucian carp tofu soup every week, which can promote the development of the child's brain, improve memory, enhance immunity, and reduce the occurrence of diseases.
2, beef
Beef has the highest zinc content among all meats. Because every 100g beef contains 3.71mg zinc element, which is 45 times higher than the zinc content in pork. Moreover, the zinc element in beef is more easily absorbed than the zinc element in plants.
beef not only contains high zinc content, but also contains a large amount of high-quality protein, iron, calcium, niacin and other essential nutrients in the human body, but not much fat. Moreover, beef enters the stomach and spleen meridians. Eating beef regularly can strengthen the spleen and stomach, nourish qi and blood, prevent and improve iron deficiency anemia , and can also strengthen muscles and bones, improve immunity . During development, eating more beef can promote brain and body development.
3, oysters
oysters contain the highest zinc content among all seafood, of which 71.2mg per 100g oysters contain 71.2mg. Moreover, the zinc in oysters belongs to protein zinc , which can be easily absorbed and utilized by the body after eating. After taking it, children can ensure the normal tissue of thymus , promote the development of brain cells, and improve memory.
In addition, the nutrient elements such as taurine , DHA, EPA in oysters can also promote the growth and development of the nervous system, the proliferation of and differentiation of cells. taurine can promote bile secretion, reduce the accumulation of fat in the liver, and promote the excretion of toxins, reducing the liver's metabolic burden; the selenium, vitamin and a variety of minerals can improve sleep quality, which is also beneficial to brain function.
Not only that, liver glycogen in oysters helps cell division and regeneration, can activate red blood cells , eat oysters frequently, and can also protect the liver and promote gallbladder. The calcium nutrition in it can also promote the development of human bones, which are of certain benefits for the elderly, adults and children.
It should be noted that oyster , as a seafood, should avoid raw food, so as not to accidentally intake parasites, bacteria, and viruses in the body, resulting in infection and harm in the body.
4, walnut
walnut is a relatively common nut on the market. Because its flesh looks similar to the brain's brain marrow tissue, many people firmly believe that eating walnuts can have the effect of strengthening the brain and enhancing the brain.
In fact, eating walnuts regularly is indeed beneficial to brain development and health.Because 100g walnuts contain 12mg zinc element and ω-3 unsaturated fatty acid , these nutrients can promote the development of brain cells and nerves, not only improve memory, but also prevent inattention, neurasthenia and other conditions.
Especially during the development period, insist on eating 3-5 walnuts every day, which not only strengthens the brain and improves intelligence, but also helps the body supplement protein, vitamins, dietary fiber and other nutrients, promotes to nourish kidney yang , improves liver and kidney function, and to moisten the intestines and laxatives . The arginine , oleic acid and antioxidant in walnuts also protect cardiovascular , which is of great benefit to development.
Not only that, middle-aged and elderly people eat walnuts in moderation every day, which can also improve brain function , prevent cardiovascular and cerebrovascular diseases and liver and kidney insufficiency , which is beneficial to health.
In addition to the four foods mentioned above, people with children should also eat more shellfish, pumpkin, peanuts, and other foods. These foods can help the body replenish zinc, are conducive to the development of brain cells and nerves, and can also maintain health. It is worth mentioning that when replenishing zinc, we should choose scientific and effective methods and try to avoid some misunderstandings.
3. The misunderstanding of zinc supplementation, everyone should be cautious
Many parents believe that as long as they are not picky about food, their bodies will not be lacking in zinc. This is not the case, because during the growth and development, some children usually suffer from intense exercise or illness, causing a lot of to sweat and diarrhea to , which may lead to a large amount of zinc loss. Therefore, children who usually have a relatively large amount of activity and are prone to illness are most likely to be zinc deficiency.
Even if children do not have zinc deficiency symptoms, parents should pay attention and often give their children foods rich in zinc nutrition . Once symptoms of zinc deficiency occur, you should go to the hospital in time and strengthen the intake of zinc to avoid affecting height, weight and intelligence development and reducing the child's immunity.
In addition to this, it is not only children who will experience zinc deficiency. After zinc deficiency in adults and the elderly, they will also reduce immunity and and increase the incidence of diseases. To this end, adults and the elderly should also pay attention to the adequate zinc element. They should not be picky, partial or over-diet. Eat more high-zinc foods to ensure their health.
It is worth mentioning that many parents have heard that calcium and zinc cannot be supplemented at the same time. It is best to supplement calcium at night and zinc in the morning. In fact, as long as the amount of calcium supplement is within 2000mg, it will not affect the absorption of zinc and other elements. At the same time, supplementing calcium and zinc nutrition, zinc nutrition may also promote the absorption of calcium nutrition. Therefore, everyone can rest assured to supplement calcium and zinc.
Doctors have something to say
Zinc is crucial to the human body. Both men, women, young and old should make the body's zinc nutritious. Especially when there are children at home, you should often give them sea fish, beef, oysters, walnuts, and other high-zinc foods to help children's brain develop better. If you find that your child is not focused, partial or abnormal eating, etc., you should be alert to zinc deficiency and seek medical treatment in time.
