1, milk
Half a catty of milk contains 300 mg of calcium, and also contains a variety of amino acids, lactic acid, minerals and vitamins to promote the digestion and absorption of calcium. Moreover, the calcium in milk is more easily absorbed by the human body, so milk should be the main food for daily calcium supplementation. Other dairy products, such as yogurt, cheese and milk tablets, are good sources of calcium. Health tip: you should also have a choice when drinking milk in summer.
2, kelp and shrimp skin
Kelp and shrimp skin are both high-calcium seafood. If you eat 25 grams a day, you can supplement 300 milligrams of calcium. But also can reduce blood lipid and prevent arteriosclerosis.
Kelp cooked with meat or cooked with cold sauce is good food. Shrimp skin contains more calcium, and 25 grams of shrimp skin contains 500 mg of calcium. Therefore, it is a good choice to make soup or stuffing with shrimp skin.
Friendly reminder: people who are allergic to seafood should eat carefully.
3. Bean products
Soybean is a high protein food with high calcium content. 500 grams of soybean milk contains calcium 120 mg, and 150 grams of tofu contains calcium as high as 500 mg. Other bean products are also good products for calcium supplementation.
Friendly reminder: Soymilk needs to be cooked 7 times before it can be eaten. On the other hand, tofu should not be eaten with some vegetables, such as spinach. Spinach contains oxalic acid, which can combine with calcium to form calcium oxalate conjugate, thus hindering the absorption of calcium by human body, so bean products such as tofu are not suitable for cooking with spinach. But if bean products are cooked with meat, they will be delicious and nutritious.
4. Animal bones
Animal bones are more than 80% calcium, but it is insoluble in water and difficult to absorb, so it can be broken in advance when made into food, and then cooked slowly with vinegar. When eating, remove the oil slick and add some vegetables to make a delicious soup.
Friendly reminder: fishbone can also supplement calcium, but pay attention to choosing the right method. Dry fried fish and braised crispy fish can soften fish bones, which is more convenient for calcium absorption and can be eaten directly.
5. Vegetables
There are also many varieties of vegetables with high calcium content. The calcium content of Chinese cabbage, rape, fennel, parsley and celery, which contain 230mg calcium, is also about 150mg per 100g.
Friendly reminder: These green leafy vegetables can get 400 mg of calcium by eating 250 grams a day.
6, calcium drugs
The calcium supplement products on the market now are suitable for children, teenagers, pregnant women/lactating women, the elderly, and even white-collar women who are nervous, stressed and have irregular lives. Its advantages are simple operation and easy control of replenishment.
Friendly reminder: When taking it, you need to strictly follow the doctor's advice to avoid taking too much, which will have adverse effects on your health. Some multivitamins and calcium supplements are more beneficial than simply supplementing calcium because vitamins themselves can produce synergistic effects with calcium.
It is better to supplement calcium with food.
It is very important to supplement calcium for your baby, which is a topic that many parents care about. There are many kinds of calcium agents on the market. Although some advertisements claim to have a high absorption rate, the actual effect is far from the expected value. Some doctors think it is best to supplement calcium with food.
Cooking food scientifically can increase calcium intake. Here are some ways to cook foods rich in calcium:
1. Small yellow croaker can be made into crispy fish. The practice is: heat the pot, put the onion and ginger into the pot, put the small yellow croaker about 10 cm on it, add a proper amount of vinegar and stew it with slow fire, even the fish head and bones will become brittle. In this way, the whole fish becomes an edible calcium agent.
2, pressure cooker chicken. You can make chicken and chicken bones as crisp as possible, encourage your baby to chew cartilage and swallow it, or you can supplement calcium.
Of course, neither of the above two foods is suitable for babies before the age of 2. After two and a half years old, most babies have grown 20 deciduous teeth. Only when they have chewing ability can they be given this kind of food, otherwise it will not be easy to digest and absorb.
You can also make big bone soup. Wash the bought big bones, break them or break them, put them in a pot and blanch them in cold water, add the bones, boil them, skim off the floating foam, add onion, ginger and cooking wine, and stew them for a long time on low heat. Let the baby eat soup and bone marrow. This is a very good calcium supplement food, suitable for babies of all ages. Soup can also be added to other baby foods for mixed feeding. For example, bone soup noodles, steamed egg soup and so on. Shrimp skin and tofu contain high calcium content and should be given to your baby often.
In addition, the weaned baby should also ensure at least 250 ml of milk every day to increase calcium intake.
Many people think that calcium can be supplemented by diet, but in fact, many casual and incorrect eating behaviors will make you lose a lot of calcium in your daily diet.
Phosphorus loss of calcium: the imbalance of calcium and phosphorus ratio is the chief culprit leading to calcium deficiency. Under normal circumstances, the ratio of calcium and phosphorus in human body is 2∶ 1. However, in real life, people eat too many phosphorus-containing foods, such as carbonated drinks, cola, coffee, hamburgers, pizza, wheat germ, animal liver, French fries, etc., which makes the calcium-phosphorus ratio as high as1:10 ~ 20.
Calcium supplementation does not supplement magnesium, and you will regret eating it: people only pay attention to vitamin D when supplementing calcium, but often don't know about magnesium supplementation. Like twin brothers, calcium and magnesium always appear in pairs, and the ratio of calcium and magnesium is 2∶ 1, which is most beneficial to the absorption and utilization of calcium. Therefore, when supplementing calcium, remember not to forget to supplement magnesium. Foods rich in magnesium include nuts (such as almonds, cashews and peanuts), soybeans, melon seeds (sunflower seeds and pumpkin seeds), cereals (especially rye, millet and barley) and seafood (tuna, mackerel, shrimp and lobster).
Big fish and big meat "eat" calcium: a high-protein diet is the cause of osteoporosis. Someone has done such an experiment: A: Taking 80 grams of protein every day will lead to 37 mg of calcium loss; B: Taking 240 grams of protein every day and supplementing 1400 mg of calcium will lead to the loss of 137 mg of calcium. Extra calcium supplementation can't prevent calcium loss caused by high protein. Excessive intake of big fish and meat without paying attention to acid-base balance will lead to a large loss of calcium. So, how does diet promote the absorption of calcium? Vitamin C promotes the absorption of calcium: If foods with high calcium content are taken together with vitamin C and pickle juice, or made into navel oranges, grapefruit, oranges, citrus and lemons, the bioavailability will be enhanced by 65,438+02%. Obviously, it is the participation of a large amount of vitamin C in these fruits that makes calcium better absorbed by the small intestine.
Balance between meat and vegetables improves the utilization rate of calcium: for example, stewed fish with tofu contains vitamin D, and tofu is rich in calcium. Vitamin D can promote the absorption of calcium and greatly improve the utilization rate of calcium in tofu. In addition, the staple food pays attention to the collocation of cereals and beans, which can not only complement amino acids to the best, but also promote the absorption of calcium.
1. Do you need calcium?
Many experts in the world believe that calcium deficiency is a serious disease that threatens human beings at present, which makes hundreds of millions of people around the world suffer great mental and physical torture and directly affects the improvement of human quality. Experts call on all sectors of society to attach great importance to it!
Of the calcium obtained by the fetus from the mother, 99% is used for bone formation, and only 1% is free in the blood in the form of ionized calcium, which is called "serum calcium". However, the data show that after birth, everyone is in a situation of calcium deficiency to varying degrees. People of any age are short of calcium, especially children and the elderly. Scientists found that from the age of 20, the total weight of bones decreased at the rate of 1% per year, and after the age of 50, the total weight of bones decreased by 30%-a scientific and amazing conclusion.
Because of "calcium hunger", the so-called "calcium movement" in the body is caused. In other words, the calcium in the bones is constantly escaping into the blood to maintain the normal level of serum calcium. The ratio of bone calcium to blood calcium must be kept in balance for a long time, otherwise there will be abnormal imbalance of calcium metabolism, such as "calcium movement" A person's calcium deficiency for a few days or a month or two will not affect serum calcium for the time being, but if this continues, calcium deficiency diseases will occur: children show sparse hair, anorexia, restlessness, night terrors, rickets, etc. Adolescent skeletal dysplasia, visual impairment, etc. ; Pain in pregnant women's waist and legs affects fetal development and even causes deformity; Osteoporosis, degenerative hyperosteogeny, lithiasis, hypertension, diabetes, dementia, etc.
Obviously, calcium plays an important role in the process of life.
Why do we eat calcium-containing foods every day, such as beans, dairy products, aquatic products, shells, bones and so on. And our bodies are still short of calcium? It turns out that the calcium contained in food is mostly dissolved calcium salt, which is not easy to be absorbed. Moreover, when eaten with cereals and dishes, phytic acid contained in cereals or fatty acids contained in meat will turn calcium into insoluble calcium salt, which cannot be absorbed. According to modern nutrition standards, the biological dose of calcium (ionized calcium for short) should not be less than 800 mg for adults and 1000 mg for children in China. Unfortunately, for a long time, the medical community mistakenly regarded calcium salt as pure calcium (that is, ionized calcium), so that many medicinal calcium in the past could not really supplement calcium. Fortunately, this fallacy has been discovered and corrected in recent years. A molecular calcium, a ionized calcium, only a word difference, triggered a worldwide human "calcium revolution"!
Calcium deficiency requires calcium supplementation, and everyone should raise their awareness of calcium supplementation. The question is, what kind of calcium should be supplemented and how should it be supplemented? Although the medical community has long recognized that calcium supplementation is a difficult problem, the ideal calcium preparation should meet three conditions, namely, ① it contains both high quantity and high quality pure calcium; ② It can be fully dissolved; ③ It is easy to be absorbed and utilized after taking. At present, many safe and efficient new calcium nutrition fortifiers have been developed, which are more and more in line with scientific requirements.
In daily food, the best sources of calcium are milk and dairy products, which are not only rich in content, but also have high absorption rate. It was found that the content of calcium in shrimp shell was very high, reaching 2000 mg/ 100 g, and it had good solubility. It is an ideal calcium supplement for biological protein calcium crystals, and eating shrimp shell meat is unscientific! Commonly used foods rich in calcium are beans (soybeans, mung beans, black beans and their products), walnuts, sesame seeds, seaweed, kelp and so on.
However, please remember: it is best to take calcium on an empty stomach one hour before meals.
2. Shortcut of calcium supplement-eat less salt
I remember there is a saying in the ancient art of war: winning by war is not the best policy; Winning without fighting is the best policy. Applying this sentence to the problem of calcium supplementation is: if you don't supplement calcium, you can achieve the effect of calcium supplementation, and fear is the most ideal method of calcium supplementation. So, is there such a way to supplement calcium without supplementing calcium? The answer is yes, this is the shortcut to calcium supplement-eat less salt.
The method of eating less salt to supplement calcium was first put forward by British scientists. In their research, they found that the intake of salt in the diet is the main determinant of calcium excretion. That is, the more salt intake, the more calcium is excreted with urine, and the more salt intake, the worse calcium absorption. So they come to the conclusion that reducing salt intake properly is as good for bones as increasing 900 mg of calcium! In other words, eating less salt is equal to supplementing calcium, and eating less salt actually plays the role of "not supplementing calcium".
According to the statement that China residents are generally short of calcium, normal people should consume 800- 1200mg of calcium every day, and the most conservative statement is that they should consume 300-500mg of calcium every day. But in any case, eating less salt is equivalent to supplementing 900 mg of calcium every day, which can meet the basic needs of the human body for calcium. Even if there are still some shortcomings, eating less salt can increase the absorption of calcium.
Eating less salt and supplementing calcium is suitable for all people. For example, girls who grow fast eat more salt, and the excretion of calcium increases and the absorption decreases, which will lead to decalcification of bones and bone dysplasia. Another example is postmenopausal women, and the incidence of osteoporosis is already high. If you eat more salt, not only the amount of urine calcium increases, but also the loss of bone calcium increases, which will accelerate the occurrence of osteoporosis. In one study, the daily salt intake of postmenopausal women was reduced from 10.6 g to 4.4 g, and the calcium excretion and plasma calcium concentration were greatly reduced. Furthermore, if hypertensive patients continue to eat a high-salt diet, their urinary calcium excretion is much higher than that of people with normal blood pressure, and the potential danger of bone decalcification is also greater than that of people with normal blood pressure. On the contrary, eating less salt can reduce their urinary calcium and increase their bone density.
According to the standards recommended by WHO, it is advisable to take 5 grams of salt every day, not more than 6 grams. We know that people excrete 3-5 grams of salt in 24 hours, so adding 5 grams of salt to food every day is just the amount lost and replenished, which can meet normal needs. It is not easy to limit the salt intake to less than 5 grams a day. This needs to change our eating habits. Because in China, especially in the north, people generally eat more salt, which is more than12g per day, and in some places it is as high as 20-30g. It is also quite difficult to change people's traditional habit of eating salty food at once. But when people know that eating less salt can supplement calcium, or they can supplement calcium without spending money, we can gradually reduce the amount of salt in our daily life, which I think is still possible.
In Beijing, Shanghai and other places, the salt containing potassium, magnesium and low sodium has been listed, and the sodium content of this salt is only 65% of that of ordinary salt. If you eat this salt regularly, it will reduce the salt content of 1/3. Qiu Shi is a traditional Chinese medicine, and its main component is potassium chloride. Buy it, grind it, and mix it with salt in half, which can also reduce the salt 1/2.
Of course, reducing salt can also help you prevent and treat high blood pressure, reduce the risk of cardiovascular and cerebrovascular diseases, and at the same time let you lose weight, so as to achieve the purpose of losing weight and bodybuilding.
3. Why do you still lack calcium after years of calcium supplementation?
In the treatment of calcium supplementation, we often encounter a common problem, that is, some people still lack calcium after taking calcium for several years, and doctors still say osteoporosis when checking bone density. Why is this? We should understand this problem from the following aspects.
Most scholars recommend that the calcium intake for preventing osteoporosis should reach 1000- 1500mg per day. At present, most calcium preparations produced in China indicate the dosage according to the amount of calcium salt, but the amount of calcium salt is quite different from the content of calcium. For example, calcium lactate only contains 1 gram every 8 grams. The dosage of calcium supplementation must be supplemented according to the calcium content. For example, the calcium content of the commonly used Gaitianli and Holly calcium tablets is 25mg, which means that if the dietary calcium supplement reaches 600mg per day, at least 24 tablets (600mg) of Gaitianli and Holly calcium tablets should be taken every day to meet the needs of the elderly and osteoporosis patients. The principle of supplementing other calcium agents is the same, that is, according to the calcium content indicated by the manufacturer, instead of the amount of calcium salt, it is generally 600 mg per day. The dose is too small, of course, you can't get the effect of calcium supplementation.
Under normal conditions, the ratio of phosphorus to calcium in bones is 0.6, that is, there is 2 milliequivalents/liter of phosphorus for every 3 milliequivalents/liter of calcium. If the ratio of calcium to phosphorus is not appropriate, it will affect the absorption and utilization of calcium. In particular, the lack of phosphorus will lead to bone loss. Due to the decrease in intake and fear of phosphorus-rich foods such as fish, liver, meat and eggs, the elderly are not eating enough. Although they supplemented enough calcium, due to insufficient phosphorus, calcium deposition did not increase significantly. The reason why fresh milk is beneficial to osteoporosis is that the proportion of calcium and phosphorus in milk is appropriate, which can supplement calcium and phosphorus.
Improper food composition If you take too much food containing phytic acid, oxalic acid, tannic acid (such as spinach) and fatty acids (mainly lard and fat) while supplementing calcium, it will combine with calcium and reduce its absorption. In addition, some high-quality protein (such as beef, fish, seafood, lean pork, etc. ) can release amino acids in the process of intestinal digestion, which can reduce the acidity of intestinal tract, form hard-to-absorb calcium salt with calcium, and also reduce the absorption of calcium. Therefore, while supplementing calcium, we should avoid the interaction and influence of food ingredients to reduce the loss of calcium.
There are many hormones that can promote intestinal calcium absorption, the most important one is active vitamin D3. The low level of active vitamin D3 in the elderly affects the absorption and utilization of calcium. At the same time, active vitamin D3 needs to be supplemented. Other hormones that promote intestinal calcium absorption include estrogen, androgen, growth hormone and calcitonin. After menopause, estrogen decreases and intestinal calcium absorption decreases. After estrogen supplementation, intestinal calcium absorption increased and bone mass increased. Estrogen supplementation should be started as soon as possible after menopause, at least until the age of 75. Other hormones can also be supplemented in an appropriate amount to increase the effect of calcium supplementation. Of course, hormone supplementation must be carried out under the guidance of an experienced doctor.
Too little outdoor exercise will lead to osteoporosis or accelerate the occurrence of osteoporosis. If you insist on outdoor sports and receive sunshine every day, you can even refuse to accept active vitamin D3. In our country, the bone content of southerners is higher than that of northerners, because the south receives more sunlight than the north.
4. Who should supplement calcium?
Calcium supplementation is considered by many people to be only needed by children and rickets patients. Actually, this view is not comprehensive. There are many patients in clinic who need calcium supplementation.
The typical symptoms of diabetic patients are "three more and one less", that is, drinking more, eating more, urinating more and losing weight. Due to osmotic diuresis, calcium excretion in the body increases, leading to diabetic osteopathy, bone thinning, osteoporosis and even pelvic deformity or pathological fracture.
Elderly osteoporosis patients over middle age, due to endocrine dysfunction, too little activity, insufficient calcium intake and other factors, bone metabolism is impaired, bone formation is reduced, calcium is lost too much, and osteoporosis, bone degeneration, low back pain, hunchback and even pathological fractures occur.
Some pregnant women have low back pain and calf cramps. Due to the growth and development of the fetus, the demand for calcium increases, which leads to calcium deficiency in pregnant women. In addition, low birth weight infants, premature infants, malnourished infants and children with chronic diarrhea should pay attention to calcium supplementation. Calcium deficiency in children will not only affect growth and development, but also lead to many diseases.
Scientific research in recent years has proved that long-term use of antiepileptic drugs in epileptic patients will lead to different degrees of bone mineral density reduction and abnormal bone metabolism. Once calcium deficiency often leads to seizures, it is difficult to control and needs long-term use.
People who drink a lot of alcohol for a long time or often drink tea and coffee should pay attention to calcium supplementation. Because of drinking, bone metabolism disorder, easy to cause osteoporosis. Drinking tea and coffee for a long time will increase the excretion of calcium due to diuresis, which will easily lead to calcium deficiency in the body.
Hypoparathyroidism "hypoparathyroidism" or hypoparathyroidism can lead to decreased intestinal calcium absorption, which in turn leads to decreased blood calcium. The patient has a series of symptoms, such as numbness, tingling, stiffness and spasm.
Calcium supplementation should pay attention to the following points: ① Try to take calcium from the diet and eat more foods rich in calcium. ② For patients with diabetic osteopathy, besides actively treating diabetes, calcitonin and calcium can be combined to promote the formation of osteoblasts. ③ Old people and children with calcium deficiency should pay attention to increasing outdoor activities and getting more sunshine. ④ Pay attention to the supplement of protein and vitamin D to promote the absorption of calcium, but the dosage of calcium supplement should not be too large to prevent urinary calculi.
What do middle-aged people need most? Hello! If middle-aged people can study hard and stick to the key to health preservation, it will help to prolong life. Put forward twenty methods for reference of middle-aged friends. 1. Pay attention to your own weight when measuring your weight. Being too fat will shorten your life span. Use a simple calculation method, that is, divide the square of height by weight. If the number exceeds 25, it is overweight. For example, your height is 1.70 meters. If we use 1.70× 1.70, the result is 2.89. If your weight is 75 kg, use 75÷2.89 and the result is 25.95. (The normal index is 20-25) 2. Smoking and not smoking will reduce the average life expectancy 10 years. Among those who died between 40 and 50 years old, 30% died of diseases related to smoking. Lung cancer and bronchitis caused by smoking account for 9% of the total number of patients; 20% of smokers suffer from heart failure. But if you quit smoking before the age of 50, you can still recover. 3. Drink less. For some people, alcohol is a special danger. For example, smokers who drink a lot of alcohol may increase their risk of esophageal cancer by 44%; Alcohol will increase the possibility of liver cancer, oral cancer and laryngeal cancer; Alcohol can raise blood pressure, which can lead to heart disease and stroke. 4. Fat control The daily fat intake should not exceed 30% of the total calories and should not be lower than 15%. A high-fat diet can lead to obesity, heart disease and hyperlipidemia. 5. Vitamins A, C and E of more fruits and vegetables have the function of protecting health, and at least 400g of fruits and vegetables (excluding potatoes) should be eaten every day. 6. Fiber-rich food is an important source of vitamins and minerals. Dietary fiber helps digestion and protects you from gastrointestinal diseases. 7. Middle-aged people who eat more calcium should pay attention to calcium supplementation. Fish, almonds, green vegetables and dairy products (skim milk) are rich in calcium, so eat more. 8. Heavy starch starch can protect you from bacterial infection and prevent heart disease and cancer. There must be bread and rice in the diet, and you can also eat 80 grams of lentils or potatoes every day. 9. Eating fish often can prolong life. Fish is low in fat, and most of it is necessary for human body. Eating more fish can enhance people's immune function and improve their ability to prevent and treat diseases. 10. Eat less salt. Eating more than 0/0 times of the body's requirement/kloc-every day is at risk of hypertension and heart disease, especially for middle-aged people with chronic kidney disease and liver disease. 1 1. Drinking less coffee is directly related to heart attack. People who drink six cups of coffee a day have a threefold increased risk of dying of heart failure. 12. Eating less sugar will not only destroy teeth, but also increase the risk of obesity, diabetes and hypertension. 13.45 The proportion of men who exercise regularly is three times less than that of men who don't exercise. You should exercise for 30 minutes every day. Old people should engage in less strenuous exercise, such as walking, cycling, climbing stairs, etc. 14. Avoid promiscuous sexual life. Aside from the risk of suffering from sexually transmitted diseases such as AIDS, changing * * will cause psychological pressure and make life lose its rhythm. 15. light fame and fortune can't ignore health and pursue promotion at all costs. Overwork and unstable life are important factors that affect life expectancy. 16. Doctors who choose to live in unsuitable environments often get sick or upset, and middle-aged people should try their best to improve their living conditions. 17. Choose a job that you like and can do, otherwise your career will have a bad influence on your life. 18. Middle-aged people who avoid traffic accidents, if they can study hard and stick to the main points of health preservation, will help to prolong life. Put forward twenty methods for reference of middle-aged friends. Car accidents are the fourth biggest killer of human beings, and the mortality rate is second only to cardiovascular and cerebrovascular diseases, cancer and respiratory diseases. 19. Don't disturb yourself. Negative emotions (nervousness, anxiety, depression) can make people sick. Don't dwell on the sad and distressing things in life, especially death, accidents and diseases. 20. People who should get married and have a spouse have a significantly lower premature death rate than those who are single and widowed. In terms of rest, middle-aged people should not commit the taboo of health preservation in daily life-hard cooking. When the body is tired, the body that can't stand fatigue needs to recover its physical strength as soon as possible, which is also the automatic control signal and early warning signal of the human body. If we don't take immediate measures to restore our physical strength according to this signal, then the human body will break down from constant overwork. Therefore, when middle-aged people feel that they have symptoms such as general weakness, muscle aches, dizziness, slow thinking, listlessness, palpitation, rapid heartbeat and shortness of breath, they should stop insisting and rest immediately. Middle-aged people should not stay up late to do wonders. At the same time, they should relax their minds, be broad-minded and feel comfortable. Don't worry about trifles, don't care too much about personal gains and losses, and take health care measures as soon as possible to eliminate physical and mental fatigue. The physiological functions of brain, heart, liver, kidney and other important organs of middle-aged people are declining unconsciously, and the immune ability, regenerative ability and endocrine function of cells are also declining. Middle-aged people do not pay attention to headache, fever, cough, fatigue, backache and leg pain, bloody stool and other uncomfortable symptoms. If left unchecked, it is easy to get serious because of delaying the illness. Therefore, when you are sick, you should go to the hospital for treatment as soon as possible, restore your health as soon as possible, and don't cause serious illness. It is the most necessary substance for human body not to boil water hard in diet. Middle-aged people must develop the habit of drinking water regularly, and it is advisable to drink 6-8 glasses of water every day. Thirst is a signal that the human body is short of water, indicating that the cells in the body are dehydrated. If left unchecked, it will affect health. Eat immediately when you are hungry, and don't delay eating time casually, otherwise it may cause gastrointestinal contraction, abdominal pain, dizziness and even coma and shock. Often hungry and not eating, it is easy to cause ulcers, gastritis, indigestion and other diseases. Middle-aged people are under great pressure, so they should pay more attention to the combination of work and rest and arrange rest and sleep reasonably. 1. Choosing the best lying posture Modern medical people believe that lying on the right side is beneficial to health, because the heart leans to the left side of the chest. When lying on the right side, the muscles of the whole body relax, the chest is not oppressed, and breathing is comfortable, which can ensure oxygen supply to the whole body when sleeping. 2. The best direction Many scholars believe that sleeping with head facing south or north, along the north-south direction of geomagnetism, can produce biological magnetization effect, strengthen bioelectricity, be beneficial to organ function regulation, and be easy to be healthy. 3. Optimum temperature Generally speaking, people can sleep peacefully at the ambient temperature of 15-24℃. 4. The Best Time According to a survey by the American Cancer Society, adults who sleep for 7-8 hours a day live the longest, and those who sleep less than 4 hours have twice the disability rate as normal people. People who sleep more than 10 hours a day are not good for their health. 5. The best pillow height for adults is 10- 15cm, which is equivalent to a sleeper's shoulder height. 6. The best bed As far as the physiological bending requirements of the spine are concerned, Simmons bed and spring bed are not ideal beds. The best bed is a wooden bed, followed by a mattress on a brown shed bed, which can keep the spine in a normal state.
In addition to calcium tablets and vitamin E, what do the elderly need to supplement most? According to the situation of the elderly, a balanced diet is the most important thing.
What vitamins do people need most? All vitamins are necessary. Lack of any one will cause serious damage to the body, and symptoms can be alleviated or disappeared after timely supplementation.
Middle-aged people around 50 years old had better eat spirulina or vitamins, because spirulina is the most abundant and balanced organism known to mankind at present, and the nutritional content of 1g spirulina powder is equivalent to the sum of 1000g of various vegetables and fruits. The protein content of spirulina is as high as 65%-7 1%, and the amino acid composition of protein is similar to human blood protein, so it is easily absorbed by human body. Spirulina is also rich in vitamins, trace elements, phycocyanin, linolenic acid, insulin-like substances and other bioactive substances. Under certain conditions, these effective components have many medical and health functions, such as lowering cholesterol, relieving nephrotoxicity, improving human immune function, promoting prostaglandin synthesis, inhibiting and preventing cancer, and accelerating wound healing. But it can't replace drugs to treat diseases.
Do middle-aged people with reduced bone mass need to supplement vitamin D in summer? @ Wash shrimp skin, 3 times a day, 2 tablespoons each time, cheap and convenient, without adding vitamin D and additives. Easier to absorb than any artificial calcium tablets.
What vitamins do adults need to supplement? Young people generally don't need supplements as long as they have a balanced diet! If you want to make up, you can make up some VC, and nothing else is necessary! Unless there is a special reason!
The elderly can supplement VC (antioxidant), VB (nutritional nerve) and ve (antioxidant). Prevention of thrombosis)
Children need to supplement VA and VC.
Pregnant women should be supplemented with folic acid and VC
People in China are generally short of B vitamins, so we can supplement them appropriately.
What effect does vitamin b 12 have on human body? Who needs vitamin b 12 most? A few people with malabsorption should pay special attention. The function of vitamin b 12 is 1, which promotes the development and maturity of red blood cells and prevents pernicious anemia. 2. Improve the utilization rate of folic acid and promote the metabolism of carbohydrate, fat and protein. 3. It can promote the synthesis of protein and play an important role in the growth and development of infants. 4, eliminate irritability, concentrate, enhance memory and balance. 5. It is an indispensable vitamin for the sound function of nervous system, and participates in the formation of lipoprotein in nervous tissue. Vitamin B 12 deficiency symptoms 1, pernicious anemia (red cell deficiency). 2, irregular menstruation. 3. The eyes and skin are yellow, and the panel appears regional (small) redness (anodyne) accompanied by molting. 4, nausea, loss of appetite, weight loss. 5, lips, tongue, gums are white, gums bleed. 6, headache, memory loss, dementia. 7. It may cause people's mental depression. 8, causing megaloblastic anemia (pernicious anemia). 9, spinal cord deformation, nerve and peripheral nerve degeneration. 10. Mucosal inflammation of tongue, mouth and digestive tract. 1 1, if there are symptoms such as loss of appetite, indigestion, tongue inflammation, and decreased taste. , is a warning of vitamin b 12 deficiency. Children with 12 and vitamin B 12 deficiency show symptoms such as abnormal mental mood, dull expression, less crying and noisy, slow response, and love to sleep, which will eventually lead to anemia. 13, increasing the risk of heart disease. Usage and dosage of vitamin b 12: 1, intramuscular injection: 50-200μg each time, 1 time, daily or every other day. When treating nervous system diseases, the dosage can be increased as appropriate. 2. Oral: 25μg each time, 3 times a day.
50-year-old middle-aged people need calcium. Which vitamin D is suitable, vitamin D400iu or vitamin D 800iu, can help the absorption of calcium.
But magnesium and phosphorus also have this effect.
Sunbathing contributes to the safe absorption of vitamin D,
Cod liver oil is also a safe supplement!
It is not recommended to use synthetic vitamin D because the body doesn't know!
How to supplement vitamin D for middle-aged people The content of vitamin D in natural food is less, which can't meet the needs.
Vitamin D mainly exists in marine fish, animal liver, egg yolk and lean meat. In addition, nutritional fortified foods such as skim milk, cod liver oil, cheese, nuts and seafood, and vitamin D were added. It is also rich in vitamin D. Plant food contains almost no vitamin D.
