First, don't follow the advertisement. Increase your health care knowledge and correctly understand calcium supplementation. Calcium production enterprises often take stars as precursors to attract consumers. Make choices according to your own needs, and don't be confused by all kinds of loud calcium supplements. Remember that such business terms are purely hype, and most of them do not exist in the field of nutrition.
Second, don't listen to the exaggerated propaganda of some calcium supplement products. For example, some advertisements call it "good deposition and quick absorption", which makes people mistakenly think that the absorption of calcium by the human body is a simple process. In fact, calcium first enters the human body, then forms calcium-containing cells, and then penetrates the outermost hard layer of bones through complex changes and is fixed in the bones inside. Another advertisement claims that its products are "several times smaller than ordinary products". In fact, the particle size is only a physical change, which can not improve the absorption rate of calcium in human body. The absorption rate of calcium in calcium supplement products is only about 30%, and there is no so-called "95%" absorption rate.
Third, by improving the diet structure, try to get enough calcium from natural foods. In the family's daily food, milk, cheese, eggs, bean products, kelp, seaweed, shrimp skin, sesame, hawthorn, marine fish, vegetables and so on. Especially milk, every 100 g of fresh milk contains calcium 120 mg, and if each person drinks 250 g of milk every day, it can provide 300 mg of calcium; Drinking 500 grams of milk every day can supply 600 milligrams of calcium; Plus about 300 mg of calcium supplied by other foods in the diet, it can completely meet the human body's demand for calcium. It is worth noting that when eating these foods rich in calcium, we should avoid eating too much foods rich in phosphate, oxalic acid and protein, so as not to affect the absorption of calcium.
Fourth, to detect the content of calcium, you should go to a regular hospital. The "single photon bone density tester" placed in shops and pharmacies can only measure the ulna and radius of the arm, and the main harm of calcium loss is calcium deficiency in the lumbar spine and hip bones, so this test is not accurate. Moreover, such instruments are radioactive sources, and their radiation will have an impact on the body.
Five, calcium products are not as expensive as possible, and should be chosen according to their own needs. There is little difference in the quality of calcium products circulating in the market. And different calcium supplement products are suitable for different people. Calcium carbonate has high net calcium content and high absorption rate. It is a traditional calcium supplement preparation, but it is not suitable for people with gastric acid deficiency. Calcium phosphate is high in phosphorus, but it is not suitable for chronic renal insufficiency.
Sixth, calcium supplementation is not as much as possible. See, absorption is very important. Every time the intake of elemental calcium exceeds 200 mg, the absorption rate will be reduced.
Seven, calcium deficiency in the elderly is an important cause of osteoporosis, and calcium intake should be strengthened from two aspects: improving diet and taking calcium products.
When the elderly ingest calcium-containing food, they should consider their own physical condition, eat reasonably and moderately, and promote body absorption; When taking calcium supplements, we should pay attention to the weak absorption capacity of calcium in the intestine of the elderly, and simply taking calcium preparations can not effectively prevent osteoporosis from the pathogenesis. You must take a certain dose of vitamins to prevent calcium loss, improve the absorption capacity of calcium in the intestine, and promote bone metabolism and bone formation. However, it is particularly important to note that calcium supplementation alone cannot comprehensively prevent and treat osteoporosis. Endocrine disorders, decreased vitamin D activity, reduced exercise and excessive salt intake may all lead to osteoporosis in the elderly.
Eight, children's calcium supplementation should be based on complementary food, and special attention should be paid when taking calcium products. Children's gastrointestinal function is weak, so do not choose strong alkaline calcium products, such as calcium carbonate and activated calcium; You can't drink soda and carbonated drinks at the same time when taking calcium products, so as not to reduce the absorption rate. In addition, children who consume too much calcium will inhibit the absorption of zinc, so children who lack zinc should be supplemented by food.
Nine, when taking calcium products containing vitamin D, beware of accumulation poisoning. Many consumers think that calcium supplementation can only be combined with vitamin D, which is a misunderstanding. Due to the general differences among human beings, not all people lack calcium and vitamin D at the same time. Some people take vitamin D for a long time, but it will inhibit the formation of their own vitamin D in the body, or cause a large intake of vitamin D and accumulate poisoning. The symptoms of poisoning are liver and kidney function damage and soft tissue calcification caused by hypercalcemia, which are manifested as loss of appetite, unresponsiveness, arrhythmia, dyspnea, nausea and vomiting.
Ten, some patients with diseases should be supplemented with calcium under the guidance of a doctor. It is found that improper calcium supplementation in patients with heart disease will lead to personal accidents due to calcium deposition. Therefore, patients with cardiovascular diseases such as hypertension and coronary heart disease should take calcium supplements reasonably or take calcium preparations under the guidance of specialists to achieve the purpose of lowering blood pressure, and should not blindly take calcium supplements to avoid accidents. In addition, patients who are taking hormone drugs such as thyroid hormone, tetracycline and corticosteroids should consult a doctor first when supplementing calcium, because calcium supplements may interact with such drugs and have adverse effects on the human body. Adjusting diet: It is effective to take some high-calcium nutrition, but supplementing calcium through daily diet is the most basic, safest and most economical way. According to modern nutrition standards, the daily calcium supplement for adults and children in China should not be less than 800 mg and 1000 mg respectively. Except for the elderly, children, pregnant women and other special groups who really need to use calcium supplements to supplement their daily diet, generally healthy adults do not need to supplement calcium supplements as long as they pay attention to eating foods rich in calcium. Foods with high calcium content abound around us, so we might as well pay more attention to our diet.
Cattle and sheep milk and dairy products are the best. 100 ml milk contains 100 mg of calcium, which is not only rich in content, but also high in absorption rate. The annual per capita possession of dairy products in the world is 105 kg, of which the United States is 170 kg, the Japanese is 80 kg, and China is only 6.6 kg. Experts pointed out that increasing milk intake is one of the most economical and effective ways to solve calcium malnutrition in China.
Kelp and shrimp skin are seafood with high calcium content, and 100 g of shrimp skin contains 2000 mg of calcium. Calcium in fish, especially marine fish, combines with protein, which is beneficial to the digestion and absorption of calcium. Processed fish products or cans, some fish bones can also be eaten, and they are also foods rich in calcium. Beans (soybeans, mung beans and black beans), especially tofu, soybean milk and bean products, contain high calcium. 100 g soybean milk contains 40 mg of calcium, and 100 g tofu contains up to 300 mg of calcium. Plant hormones contained in bean products have a good effect on the prevention and treatment of osteoporosis. Adding some electrolytes in the process of marinating tofu can precipitate protein, which is also good for bones.
More than 80% of animal bones are calcium. Adding vinegar to simmer soup helps to absorb calcium.
Foods rich in calcium include eggs, sesame seeds, walnuts, fungus, laver, almonds, oranges, mushrooms and some vegetables.
Exercise and sunbathing can increase the absorption of calcium.
Athletes' bone density is higher than that of people who sit much, and most people's right arm is higher than that of their left side, which shows that exercise can increase the density and strength of bones. One of the reasons why the bone calcium content of southerners in China is higher than that of northerners is that the south receives more sunlight than the north. Ultraviolet rays in sunlight can promote the synthesis of vitamin D and increase the storage of vitamin D in the body. Vitamin D contributes to the absorption of calcium and phosphorus in intestine and promotes the deposition of calcium and phosphorus in bone tissue. Adults don't need to take vitamin D if they insist on outdoor sports and receive sunlight every day. It is best for the elderly to avoid walking in the morning and evening, and do more activities during the day to increase the chances of sunbathing.
Various factors affecting calcium absorption
Calcium-phosphorus ratio: Under normal circumstances, phosphorus deficiency can also lead to bone loss, and the calcium-phosphorus ratio in bones is 1: 0.6. If phosphorus intake is insufficient, the ratio of calcium to phosphorus is not appropriate. Although sufficient calcium was supplemented, the absorption and deposition of calcium did not increase significantly. One of the reasons why milk is beneficial to osteoporosis is that the proportion of calcium and phosphorus in milk is appropriate, which can supplement calcium and phosphorus.
The role of vegetable acid and oxalate: foods such as cola drinks, alcohol and spinach contain vegetable acid, oxalic acid and tannic acid, which can combine with calcium ions to form insoluble calcium salts, affecting the absorption of calcium. Taking calcium preparation between meals can avoid the influence of unfavorable factors in food and is beneficial to the utilization of calcium. Taking calcium preparation in batches is more effective than taking it centrally.
The role of salt: the more salt in the diet, the worse the absorption of calcium, and the more calcium discharged from the urine. In one study, the daily salt intake of postmenopausal women was reduced from 10.6 g to 4.4 g, the calcium excretion was greatly reduced, and the bone mineral density was significantly increased. According to the standards recommended by the World Health Organization, the daily salt intake of adults is 5 grams.
The role of sex hormones: Estrogen, androgen, growth hormone and calcitonin are the main hormones that affect the absorption and deposition of calcium in human body and can effectively prevent osteoporosis. Estrogen decreases after menopause, and estrogen supplementation can increase bone mass, but hormone supplementation must be carried out under the guidance of a doctor.
The role of iron agent: iron has a certain inhibitory effect on the absorption of calcium, and the absorption of iron by calcium is also unfavorable. It is best to separate the time of calcium supplementation and iron supplementation for anemia patients. Calcium advantage of Iraqi molecular casein
Iraqi molecular seabuckthorn casein calcium tablets are a new generation of calcium supplement products developed by experts in pharmacy, nutrition and biology of Shenyang Pharmaceutical University. The formula of this product is novel and unique, and its main components and functions are as follows:
Calcium caseinate, a new calcium source, can supplement both calcium and protein. It is a new compound prepared by reacting casein ions in milk with calcium ions by modern biotechnology. It has dual functions of supplementing calcium and protein, and the absorption rate of human body is over 92%, which is 1.75 times of calcium lactate, 2. 15 times of calcium carbonate and 5.5 times of shell calcium. It is an ideal new raw material for calcium supplementation without VD.
Casein calcium peptide is a kind of bioactive short peptide rich in phosphoserine residue, which is a powerful calcium absorption promoter and easy to be absorbed by human body. It can combine with calcium to form soluble complex in weak alkaline environment of small intestine, which can effectively prevent the formation of insoluble calcium phosphate, increase the concentration of calcium ions in intestine, promote the absorption of calcium in intestine, and do not hinder the diffusion of calcium ions to intestinal mucosa, so it is called "carrier of minerals".
Collagen-calcium high-efficiency bone fixative Human skeleton is composed of 1/3 collagen and 2/3 calcium salt. The loss of collagen in bone will reduce the level of calcium in bone, and the lack of collagen will make calcium unable to cement in bone. Collagen supplementation can effectively improve bone density and bone toughness and prevent osteoporosis. Collagen plays an important role in calcium fixation.
Seabuckthorn-a treasure house of natural nutrition and an effective booster for calcium supplementation. Seabuckthorn is the most active plant in nature and the crown of vegetative plants. More than 200 active substances have been detected in Hippophae rhamnoides L., mainly including flavonoids, phospholipids, vitamins, trace elements, protein and amino acids, oils and fatty acids, serotonin, volatile oils, phenols and organic acids, steroids and so on. It has irreplaceable health care function for preventing and treating various cardiovascular and cerebrovascular diseases, malignant tumors, digestive system diseases, diabetes, liver diseases, kidney diseases, etc.
