Zinc is a trace element, the content of the human body and the daily intake is very small, but the body's sexual development, sexual function, the generation of germ cells
But it can play a pivotal role, so there is a "spark of life" and "marriage harmony" called "marital harmony".
The body's normal zinc content of 2-3 grams. The vast majority of tissues have a very small amount of zinc distribution, in which the liver, muscle and bone in the higher content. Zinc is the main ingredient of dozens of enzymes in the body
. Zinc is also associated with brain development and intelligence. A U.S. university found that smart, good teenagers, the body contains a higher amount of zinc than stupid
obtuse people. Zinc also promotes the role of lymphocyte proliferation and activity, to maintain normal epithelial and mucosal tissues, defense against bacterial and viral invasion, and promote the injury of lack of
Zinc deficiency in the whole body systems will be adversely affected. In particular, it has a more direct effect on gonadal maturation at puberty. Young men in the Nile Delta of Egypt suffer from
zinc deficiency, mainly in the form of growth retardation and hypogonadism. In Iran, studies have shown that adolescent girls and schoolchildren with growth retardation and delayed sexual maturity
Food fortified with zinc quickly normalized the patient's development.
Animal experiments have shown that zinc-deficient animals have poor brain development.
Zinc deficiency in certain tissues of the eye affects the photochemical process and makes vision abnormal.
Zinc is also a component of insulin, and when zinc in the pancreas falls to half its normal level, diabetes is possible.
Zinc deficiency
China's people's dietary structure is based on cereal food, the bioavailability of zinc in cereal food is very low, only 20-40%, if the children eat more refined food,
which is too much loss of zinc content, more likely to lead to zinc deficiency.
(A) Causes:
1. Inadequate intake of zinc, breast milk colostrum contains more zinc than mature milk, infants are not fed mother's colostrum or breast milk is insufficient, and did not add zinc-rich complementary foods in a timely manner can lead to insufficient zinc
intake.
2. Zinc malabsorption, such as chronic gastrointestinal diseases, can affect the absorption and utilization of zinc.
3. Increased zinc requirements, rapid growth and development of children prone to zinc deficiency.
4. Excessive loss of zinc, such as nephrotic syndrome; hemolytic anemia, diuretics, steroids, colloid dialysis. Excessive intake of iron and calcium increases the loss of zinc.
(2) Clinical manifestations:
Slow onset, the main symptoms are loss of taste, loss of appetite, recurrent oral ulcers, xenophagia. Growth and development are backward, sexual development is delayed, mental retardation, the skin appears
wet diagnosis, blisters or ulcers, in the junction of the skin and mucous membranes and the extremities of the frequent occurrence of long-lasting dermatitis, alopecia, easy to concur with infectious diseases, wound healing is slow
and so on. Zinc deficiency in pregnant mothers can cause fetal dysplasia. In addition, because of affecting the operation of vitamin A can also be associated with night blindness.
(3) Diagnosis:
Based on dietary survey, clinical manifestations, serum zinc measurement and zinc supplementation after the comprehensive judgment.
(4) Prevention:
Adhering to a balanced diet is the main measure for preventing zinc deficiency. Generally speaking, breast milk, especially colostrum, is the richest in zinc, so the promotion of breastfeeding is of great significance in preventing zinc deficiency.
Animal food is not only rich in zinc, but also in zinc. Animal food is not only rich in zinc, but also has a high utilization rate, and nuts are not low in zinc.
(v) Treatment:
1. Remove the cause of zinc deficiency.
2. Adjust the diet: actively supplement a variety of zinc-rich animal foods such as liver, lean meat, egg yolk and fish.
3. Zinc supplements.
4. Taking zinc should be accompanied by increased protein intake and treatment of iron-deficiency anemia, which can make zinc deficiency improve faster.
Food sources
A balanced diet for a normal person provides about 10-20 mg of zinc per day, but only 2-3 mg can be utilized. The main substance that affects the absorption of zinc is phytic acid, which forms insoluble salts with zinc in the
intestinal tract. Large amounts of dietary fiber also have an effect on zinc utilization.
To ensure that there is enough zinc in the body, the first step is to adjust the diet. Animal protein foods such as fish, meat, liver, kidney, and shellfish, effective zinc content
are rich, zinc deficient people can be in the diet with reasonable.
Special use
(The role of zinc in sexual activity)
The human body's testicles, prostate, semen, all contain high concentrations of zinc. When there is a lack of zinc in the body, the sexual function will be low, the synthesis of testosterone
Enzyme disorders, men will cause impotence and face acne. Zinc has a special role in stimulating sperm activity, and a lack of zinc can cause a decline in sperm motility.
Long-term zinc deficiency without timely replenishment, the sperm count can be significantly reduced, testicular atrophy, and ultimately lead to infertility.
The World Health Organization stipulates that the daily intake of zinc for adults is 15 milligrams, while the intake of zinc for men in China is about 9 milligrams. Zinc intake from food
insufficient, there are several reasons:
One is a large amount of fertilizers in the land, the growth of food in general lack of zinc;
Second is the deep processing of food, so that the zinc content of food is reduced;
Third is drinking alcohol, sugar consumption of zinc also consumed part of the. The human body is very easy to lack of zinc, especially married young men, because they are in the peak stage of sexual life, that is, in the drinking
food intake of zinc is relatively insufficient, but also with the semen lost a considerable part of the zinc.
The human body is deficient in zinc, the general situation can be supplemented by adjusting the diet. Shellfish such as oysters, clams, oysters, mussels, etc. contain more zinc, and in terms of zinc content, and
The first oysters, 100 grams of food containing zinc, oysters for 100 milligrams. Other foods such as animal liver, coarse grains, fish, meat, eggs also contain a considerable amount of zinc, while water
fruits contain the least amount of zinc.
All in all, zinc plays a leading role in sexual activity and plays an important role in maintaining reproductive function. Therefore, it is recommended that young men drink as little alcohol as possible and increase their intake of foods high in zinc to avoid affecting their reproductive function. Because the seminal plasma portion of semen is mainly secreted by the prostate,
So checking the zinc content of seminal plasma can be used as an indicator to monitor the function of the prostate.
Researchers have found that zinc plays an important role in maintaining the physiological state of spermatozoa as they mature, are transported, and move through the female reproductive tract and are energized during the lengthy prefertilization process. Zinc is absorbed by the sperm during ejaculation and binds to the sulfhydryl groups in the chromatin of the cell nucleus to avoid premature depolymerization of the chromatin, thus facilitating fertilization
. Zinc can also slow down the lipid oxidation of the sperm membrane, play a role in maintaining the stability of the cell membrane structure and permeability, so that the sperm can maintain good mobility.
Additionally, testicular interstitial cell synthesis of testosterone requires many enzymes to participate in the process, when the body lacks zinc can cause these enzymes to change the nature and function of the testicular
Interstitial cell synthesis and secretion of testosterone amount of reduction and so on.
Male infertility caused by zinc deficiency can be seen in oligozoospermia, which is characterized by a decrease in the number of spermatozoa, and dystocia, which is characterized by poor sperm motility. So when you encounter the above situation, you can
Check the zinc content in the seminal plasma, if it is the cause of zinc deficiency, you can use zinc supplementation method of treatment. Generally, 0.5% zinc sulfate solution can be used orally
after meals, 20 milliliters each time, three times a day. Foods high in zinc, such as oysters and animal livers, can also be used to help these patients achieve fertility.
Even if there is no way to test for zinc, food-based zinc supplements have no adverse effects on the body.
Zinc Gluconate
(Properties and stability) Zinc Gluconate is white crystal or granular powder; soluble in water, insoluble in ethanol, chloroform and ether. It is soluble in water, insoluble in ethanol, chloroform and ether. It should be kept in dark and sealed.
(In vivo process) Zinc gluconate is mainly absorbed by the small intestine after oral intake, and the serum zinc concentration reaches the peak after 1 hour, and begins to decline in about 2 hours. Zinc gluconate is widely distributed in the liver,
intestines, spleen, pancreas, heart, kidneys, lungs, muscles, central nervous system, bones, etc. It is mainly excreted in the feces. It is mainly excreted in the feces, and to a lesser extent in the urine and breast milk. The bioavailability of this product is 1.6 times higher than that of zinc sulfate in the case of similar zinc content
.
(Drug effects) Zinc is present in many enzymes, such as carbonic anhydrase, respiratory enzymes, lactate dehydrogenase, superoxide dismutase, alkaline phosphatase, DNA and RNA polymerase, etc., and is necessary for the synthesis of nucleic acids, proteins, carbohydrates and the use of vitamin A. Zinc has the ability to promote growth and development, as well as to promote the development of the body. Zinc has the function of promoting growth and development and improving the sense of taste. Zinc
When zinc deficiency occurs, the sense of taste and smell is poor, anorexia, and growth and mental development are lower than normal.
(Symptoms) Zinc Gluconate is a zinc tonic, mainly used for children and elderly, pregnant women due to zinc deficiency caused by growth retardation, malnutrition, anorexia,
recurrent mouth ulcers, skin acne and other diseases.
(Adverse effects and precautions)
The symptoms of gastrointestinal irritation such as stomach discomfort, nausea or vomiting can be seen. However, the digestive tract irritation is less than that of zinc sulfate.
Excessive zinc in the body can cause lead and iron deficiencies, due to interference with the absorption and utilization of the two. Excessive zinc can affect the metabolism of ketone and iron ions.
(Drug interactions) This product is contraindicated in combination with aluminum, calcium, strontium salts, borax, sulfates and hydroxides (bases), silver proteins and tannins. Combination with penicillamine may
reduce the effect of the latter.
(Usage and dosage) Oral. Adults 10 mg a day. Pediatrics, reduce the dosage as appropriate.
Zinc (Zn) Zinc is the second most abundant trace element in the body after iron, but it wasn't until the 1960s that it was recognized as an essential nutrient.
Zinc is a component of many enzymes, and it is said that more than 100 enzymes in the human body contain zinc. In addition, zinc is involved in protein synthesis and the metabolism of DNA and RNA. Blood
The transportation of carbon dioxide in the cells, the normal calcification of bones, the development and maintenance of normal function of reproductive organs, the healing of wounds and burns, the normal function of insulin and
The body's keen sense of taste and so on need zinc.
Human colostrum is a good source of zinc. The bioavailability of zinc varies widely among foods, and is much higher in meat and seafood than in vegetables.
Don't take zinc-containing medicine as a tonic
Zinc is an indispensable trace element in the human body, and if a child is deficient in zinc, it will affect growth and development, and mental retardation. If the child's body is not deficient in zinc and indiscriminate supplementation, it will be further aggravated.
What is the reason? The original human body has a certain content and proportion of trace elements, neither less, nor more. Infants and young children grow and develop faster, the need for zinc
Relatively large, but not more good, if the zinc-containing drugs as a nutritional drug, every day to let the child to take, will be harmful to health. If the zinc is too much
many, can make the body of vitamin C and iron content is reduced, inhibit the absorption and utilization of iron, thus causing iron deficiency anemia. When the child's body has too much zinc,
calcium is reduced, under the action of magnesium ions, can inhibit phagocytosis activity, decreased immunity, poor resistance to disease. Often give children drugs containing zinc,
will also make the body of zinc, copper elements of the ratio increases, affecting the metabolism of cholesterol, so that the blood lipids rise, prompting the arteries to atherosclerosis, for the future of the cardiovascular
disease buried hidden dangers. In addition, the body of zinc content is too high, there is a risk of inducing cancer.
See, there is a correct understanding of zinc, in order to make the child's body does not lack of zinc, parents should learn a scientific approach to child-rearing. The first is to do breastfeeding, because
Breast milk has enough zinc for the growth and development of infants; 4 months to gradually add complementary foods for the child, especially lean meat, eggs, animal liver, oysters
, peanuts, walnuts and other foods in the zinc content is higher, depending on the specific circumstances of the child to consume; to educate the child from childhood to become not picky about what they eat, do not eat a good
The children should be taught not to be picky about what they eat, not to be partial to good habits, pay attention to the reasonable balance of the diet structure, a mixture of coarse and fine grains, so that the children are generally not deficient in zinc. You should also be careful not to let your child eat too much
sugar and sweets, so as not to affect the absorption of zinc.
If you find that your child has anorexia or anorexia nervosa due to a zinc deficiency, you should go to the hospital and ask your doctor to check the zinc content in your child's hair or blood, and then take zinc supplements according to your body's
needs, and you can't take zinc medications as a universal "nutritional tonic" in order to prevent any harm to your child's health.
Baby sweating when zinc Wuhan Morning Post (correspondent Luo Huarong) 2002-11-12 07:50:18
Despite the late autumn, there are still a lot of children because of sweating to the doctor to do micronutrient testing found that they are deficient in zinc.
Hubei Provincial Maternal and Child Health Hospital Pediatrics Xu Haiqing explains, children's metabolism, and lively and active, so sweating is often more than adults. A lot of sweating will
make too much zinc loss, resulting in a zinc deficiency in the body. The lack of zinc reduces the body's immune system, especially the resistance of the respiratory and digestive tracts, which can lead to recurrent infections.
Dr. Xu reminded parents to add zinc-rich foods to their sweaty children. Zinc is generally found in animal foods, such as oysters, lean meats, and animal guts
Dirty foods such as walnuts, chestnuts, and peanuts are also rich in zinc. Walnuts, chestnuts and peanuts also contain a lot of zinc and can be eaten regularly.
Some children sweat a lot, not moving on the drenched, like a wash, nose, forehead, hair full of beads of sweat, even in winter is sweating, lifting
clothes cap, water vaporization.
Children sweating appropriate zinc Wen / Chen Hui (Beijing Haidian Hospital, deputy director of pediatrics) 2000-10-17
Generally speaking, children's metabolism is vigorous and active, so sweating is often more than adults. In addition, the weak, weak, rickets or tuberculosis
disease of children will also sweat.
Many trace elements in the human body are excreted through sweat, and zinc is one of them. Zinc is an essential trace element that is closely related to children's growth and development, immune
function, visual and sexual development. Children in the process of growth and development, the demand for zinc is relatively large, a lot of sweating will cause excessive loss of zinc, sweat
Children's incidence of zinc deficiency is significantly higher than normal children. Zinc deficiency will reduce the body's immune level, especially the resistance of the respiratory tract and digestive tract, so that the infection
repeated episodes, which in turn will lead to children's weakness, aggravated sweating, thus forming a vicious circle. Therefore, sweating children should be appropriate supplemental zinc.
For children under 10 years of age, the World Health Organization recommends a daily intake of 10 milligrams of zinc. Children who eat a normal diet and are free of disease should be able to get enough zinc in their diets to meet this standard. However, children with excessive sweating must eat more zinc-rich foods, such as oysters, lean meats, fish, shrimp and animal
guts, and can also take some zinc supplements, such as zinc gluconate. In addition, you can also take some traditional Chinese medicine, such as astragalus, jujube, etc., which has the function of tonifying qi and converging sweat
effect. At the same time, you should also actively treat other diseases that cause excessive sweating.
