magnesium
Magnesium (mg). Magnesium can calm the central nervous system, help to eliminate female menstrual tension and relieve psychological stress. Magnesium deficiency can lead to various headaches, including other symptoms, such as fear of light and sound. Magnesium-containing drugs (MgSO) can effectively eliminate headache symptoms.
zinc (Zn)
Zinc. Zinc is the hippocampus, located in the center of the human brain, which controls learning and memory activities. It is mainly responsible for the formation and storage of important trace elements in long-term memory, which is related to memory and intelligence. Zinc deficiency in children can lead to zinc deficiency-anorexia-insufficient intake of protein-lysine deficiency-brain development damage-zinc deficiency in hippocampus-memory and intelligence decline-emotional out of control-poor psychological quality. 1977, a paper in the American journal Science talked about the different nutritional functions of human milk and milk, which involved the intake form of zinc. Zinc series in human milk combines with small molecular weight ligands such as amino acids, which is beneficial to zinc absorption; Although the content of zinc in milk is higher than that in human milk, most of it combines with macromolecular protein ligands and is not easy to absorb. Therefore, breast milk may be more conducive to the baby's growth, intellectual development and psychological quality improvement, which is related to the absorption of zinc.
iron
Iron. Iron is the most abundant trace element in human body, mainly in the form of iron porphyrin complex (heme), which is generally considered to have the greatest effect on respiration. As the main component of hemoglobin, iron has the best oxygen transport ability because of its easy transformation between high-priced iron and low-priced iron and rapid redox reaction. The oxygen transport mechanism is HB-Fe (Ⅱ)+OH B-Fe (Ⅱ)-O, where Fe (Ⅱ) represents ferrous iron, that is, the existing form of iron at this time; Hb stands for hemoglobin. The special structure of hemoglobin makes Fe (Ⅱ) different from common ferrous ions (Fe). +), its complexing ability with O is regulated by porphyrin and other nearby ligands, and Fe (Ⅱ) is complexed with porphyrin and is not easy to be oxidized. Other hydrogen-containing ligands can form hydrogen bonds with O to stabilize oxygen adducts. When macromolecules such as Hb combine with several small molecules O, there is a synergistic effect between O, and they promote each other. This is because after deoxygenated Hb binds to the first O molecule, ferrous iron is transferred, which makes the groups on the nearby protein chain move and recombine through hydrogen bonds, thus promoting the subsequent oz binding. Iron deficiency anemia affects intelligence and mental health. It is reported that 78% of the children with short temper and hyperactivity in 1078 are iron deficient. Shanghai First Medical College also reported that the lack of trace element iron is the cause of deafness.
iodine
Iodine (I). The main function of iodine in human body is to synthesize thyroxine.
There are four iodine atoms. Iodine is an essential trace element in human body, and its physiological function is irreplaceable. Iodine deficiency is one of the known causes of human mental retardation. According to the survey, 80% of the disabled people in China 1000 in Wan Zhi are caused by iodine deficiency. Iodine deficiency in food will cause certain psychological tension and lead to poor mental state. Eating iodine-containing food often helps to eliminate tension and help sleep.
selenium
Selenium (Se) Selenium is an essential element in the process of thyroid hormone synthesis and metabolism. When selenium is deficient, it will cause the decline of thyroid function, which will lead to depression. The lack of selenium will reduce the immune function of the body, and the reduction of immune function is precisely a feature of patients with depression. Selenium is also an essential component of glutathione peroxidase in the body, which is an important antioxidant enzyme to protect the body's nerves and avoid tissue damage, and plays a role in the pathogenesis of mental disorders. Selenium can regulate the mood of depressed patients, relieve depressive symptoms, relieve pain and improve the quality of life.
Food supplement
All the elements needed by the human body are supplemented from food. Because the types and quantities of elements contained in various foods are not exactly the same, it is necessary to combine coarse grain and flour foods with vegetarian food in the usual diet, so as not to be partial or picky about food, so as to basically meet the human body's demand for various elements. On the contrary, it will cause the lack of some elements.
The lack of certain trace elements in human body can lead to diseases, such as anemia caused by iron deficiency; Zinc deficiency reduces immunity and affects development and intelligence, and iodine deficiency leads to goiter. It would be better if we could supplement food with drugs at the same time.
Iron deficiency: you can eat more black fungus, laver, animal liver, day lily, blood tofu, mushrooms, rape, yuba, yeast, sesame, clams and so on.
Zinc deficiency: you can eat more fish, oysters, lean pork, beef, mutton, animal liver and kidney, eggs, cocoa, dairy products, cheese, peanuts, sesame seeds, bean products, walnuts, brown rice, coarse flour and so on. In severe cases, zinc supplements such as Nixibao can be taken.
Magnesium deficiency: eat more kelp, laver, sesame, soybean, brown rice, corn, wheat, spinach, mustard, day lily, black dates, bananas, pineapples, etc.
Iodine deficiency: eat more kelp, seaweed, sea fish, sea shrimp and so on.
Umol/L 76.5 ~ 170。 Foods rich in zinc include seafood, such as oysters, scallops and scallops. Nuts are also high in zinc, such as walnuts, almonds and sesame seeds.
The copper element umol/l 1 1.8 ~ 39.3 is high in animal viscera, and the food cooked in copper-containing utensils is high in copper content.
Iron element mmol/L 7.52 ~ 1 1.8 Foods rich in iron include animal livers, such as chicken livers and pig livers. Bean products are also high in iron content and easy to absorb, such as soybean milk and tofu. Egg yolk has a high iron content, but its absorption rate is slightly poor, so it can be regarded as one of iron-supplementing foods. Oranges, grapes and kiwifruit are rich in vitamin C, which promotes the absorption of iron.
Calcium element mmol/L 1.55 ~ 2.65 Milk, bean products and nuts are rich in calcium. Cod liver oil promotes the absorption and utilization of calcium; Get more sunshine.
Lead element μ g/L 0 ~ 100 automobile exhaust, pencils, inferior toy furniture paints and wall coatings, second-hand smoke, batteries, preserved eggs, printer ink, etc. Lead content is high, try to keep your baby away from these things.
Fruits rich in vitamin C, such as kiwifruit, oranges and grapes, are beneficial to lead excretion.
Sea cucumber is rich in trace elements, such as selenium, alum, zinc and iron. Long-term consumption of sea cucumber tonic is beneficial to supplement the trace elements needed by the human body and keep the body healthy. [2]
Harmful trace elements
Lead, mercury, etc. Can cause diseases.
