Calcium supplement depends on age
Calcium supplement is best carried out according to age, blind supplement will be counterproductive, calcium supplement should also be moderate, can not be blindly abused. Calcium is one of the most important elements of the human body, participating in all the processes of life activities. First of all, calcium is an important component of bone and tooth structure, and about 99% of calcium accumulates on bone. Calcium ions are also involved in many physiological functions, such as nerve excitation, muscle contraction, cardiac activity, cell membrane transparency, hemagglutination process, enzyme activity and so on.
Calcium intake in the diet is insufficient at the same time, if you do not get other supplements, the body will lack calcium. Calcium deficiency can lead to insomnia, numbness of hands and feet, loose teeth, aging and other symptoms. Calcium deficiency in children can lead to rickets, calcium deficiency in pregnant women can lead to back pain male chastity , leg cramps and other symptoms, serious cases can lead to pregnancy induced hypertension syndrome. Calcium deficiency in adults can lead to osteomalacia and osteoporosis. Some experts concluded that calcium is the source of life, calcium is the basis of health, calcium is the basis of longevity is reasonable.
Chinese residents have a very serious calcium deficiency due to dietary structure and other reasons. The Chinese government has successively organized four national dietary nutrition surveys for urban and rural residents. The results show that calcium intake is obviously low, which is generally lower than the daily dietary nutrient supply (RDA) standard recommended by the Chinese Nutrition Association. The recommended standards for Chinese people's daily calcium intake and daily calcium demand are shown in Table 1.
According to the above survey data, Chinese people's daily calcium intake is lower than the recommended amount. Does everyone need calcium supplements? Because the demand for calcium mainly depends on the demand for calcium from bones. Calcium in bones is not necessarily transported from calcium in food to blood, from blood to bones, calcium in bones is also exported from bones perfect ass , excreted from the kidneys and excreted from urine. From infants and young children to teenagers, more calcium is input than output in bones, and bones grow. Adult input and output balance, middle-aged and elderly bone output more than input, bone mineral density decreased, easy to cause osteoporosis. As a result, people of different ages need different amounts of calcium.
Studies on the three age groups most in need of calcium supplements show that the three age groups in which the human body needs calcium supplements most are
The period when the bones of infants, children and adolescents need to grow. Babies have different calcium absorption due to the difference between breastfeeding and milk feeding. The absorption rate of calcium in breast milk reaches 55% to 60%. Milk is fed with ordinary milk and prescription milk, and the absorption rate is only about 40%, so babies fed only with milk must supplement calcium. Appropriate calcium supplements are enough for 10-year-old children every day. Women need to increase their calcium intake from the age of 12. Studies have shown that bone health depends on being young, with 95% of bone strength formed between the ages of 12 and 18.
Young adults need to maintain bone mineral density at the highest point, the higher the bone mineral density, to the old age is not prone to osteoporosis. At this time, the small intestine absorbs calcium well, with an absorption rate of about 40%. Generally speaking, the peak of bone mineral density occurs after the age of 20 and continues to the age of 30. This peak is very important for the nutrition of human calcium and the health of bones and teeth. At peak times, the elderly are less likely to suffer from osteoporosis. Recent studies have shown that if you supplement more than 12000 mg of calcium a day at this time, you can accumulate more calcium in bones and increase the peak bone mineral density. As a result, for young people between the ages of 20 and 30, when bone mineral density reaches its peak, 1,200 to 1500 milligrams of calcium can be added every day.
Calcium in bones is easily lost in old age. The output of calcium in the bones of 40 years old and over 50 years old is larger than the input, so osteoporosis is easy to occur. Calcium intake should be increased to 1000 mg. When women stop menstruation, estrogen begins to drop, and 17 β-estradiol can accelerate the loss of calcium. Women's menopause lasts for 6 to 10 years. Osteoporosis and even fractures are easy to occur at this time, and the dose of calcium can be used 1000 mg a day.
In addition, the bone growth of pregnant and breast-feeding female fetuses, especially in the later stage of pregnancy, requires the intake of 30 grams of calcium from the mother. During breastfeeding, 200 milligrams and 300 milligrams of calcium are delivered to the baby from breast milk every day. As a result, pregnant women and nursing mothers need 1200 milligrams of calcium a day.
How to supplement calcium?
First of all, prevent calcium deficiency in advance and increase calcium reserves. When you are young, you take more than 800 milligrams of calcium a day, and some people think that taking calcium tablets every day is OK. This is not the case. For example, calcium gluconate contains only 9% calcium, and calcium lactate contains 13% calcium, which is low in calcium, taking 2 tablets of calcium at a time and taking only the standard medical 1max 10. Because calcium is measured by compounds. Therefore, using calcium tablets to supplement calcium is not an ideal method. Calcium supplement should be based on diet, increase the intake of calcium-rich foods, take calcium appropriately, bask in the sun regularly, exercise appropriately, improve the absorptive capacity of calcium, increase the content of bone calcium in the body, supplement vitamin d when necessary, and supplement estrogen for menopausal women. These are excellent measures.
Second, it is necessary to correctly grasp the time of taking calcium: for oral supplements, it is better to take them once in the morning and before going to bed; if you take it 3-4 times a day, it is best to take it 1-1.5 hours after meals to reduce the effect of food on calcium absorption. If you choose preparations with high calcium content and use once a day, it is better to take them before going to bed every night, because people's blood calcium levels are the lowest in the middle of the night and early in the morning, and taking them before going to bed can make calcium agents more fully absorbed and utilized.
Third, the principle of scientific selection of calcium agents: at present silicone dildo , there are many kinds of calcium agents sold in the market, with more than 300 varieties, which makes people dazzling, how should they be chosen? The selection should meet the following criteria: large ① calcium content: ② solubility (water solubility) ③ intestinal absorption rate high ④ bioavailability ⑤ low content of heavy metals. At the same time, children should choose preparations with good taste and good water solubility. In addition, the content of heavy metals such as active calcium and bone meal is high, so it is easy to accumulate in the body after taking it for a long time.
Excessive calcium supplement is harmful
Calcium supplements should also be moderate and should not be blindly abused. Excessive emphasis on calcium supplement, calcium intake of more than 4 grams a day, if the duration is too long, it may have side effects, but will affect health. Its side effects may include ① hypercalcemia: fatigue, muscle weakness, lethargy, forgetting bone pain and other symptoms, which greatly increase the incidence of urinary calculi. ② iron and vitamins and other nutrients absorption disorders, excessive calcium supplement will cause obvious iron deficiency and vitamin deficiency, adverse effects on the body's metabolism and immune function ③ gastrointestinal side effects: generally speaking, calcium complex such as calcium carbonate on gastric acid secretion has a therapeutic effect, but too much calcium will cause anti-elastic gastric acid excess in addition, calcium supplement is easy to constipation. Therefore, the application of calcium should also be under the guidance of doctors bdsm chastity , according to their own actual situation, to avoid damage to health due to improper calcium supplement.
