With the deepening of health concepts, more and more people will pay attention to their own physical health, from different aspects for their own tonic, calcium is one of them, but experts advise that excessive calcium will only increase the burden on the kidneys, leading to stone disease happened. Because calcium is not so easily absorbed by the body, if too much intake can not be absorbed, but at the same time intake of oxalic acids, it may be combined to form calcium oxalate stones. Oxalic acid is abundantly present in various vegetable foods such as spinach. Some very small crystals of stones can be excreted through the urine. A slightly larger one may cause problems such as renal colic, pain and hematuria, and even worse, kidney damage. How should calcium be properly added? ◠Calcium requires vitamin D Experts said that whether or not the human body lacks calcium depends on several factors. First of all, calcium intake should be sufficient. The source of calcium is mainly milk that we are familiar with (such as breast milk, milk powder, and milk). Other foods have low calcium content or are not easily absorbed by the body. Second, calcium needs to be absorbed and utilized by the body if it enters the body. It also requires the use of activated vitamin D, otherwise calcium that is eaten will not be absorbed, and severe rickets may occur. Nutritional deficiency rickets is mainly due to the lack of vitamin D in the body, resulting in a chronic nutritional disease of calcium and phosphorus metabolism disorders. A small number of children are simply taking calcium deficiency, but the most common problem is insufficient vitamin D intake. ◠bone soup calcium is not significant Housewives often prefer to use high quality pig bones to cook soup. They believe that nutrient enrichment is the best for calcium supplementation. Is this indeed? Experts said: "The pig bone contains a certain amount of calcium, but 99% of this calcium is stored in the bones. Whether you are boiling soup or old fire soup, it cannot dissolve completely in the soup." The calcium in the bone is tricalcium phosphate. In the presence of calcium compounds, most of them are insoluble or insoluble in water, and calcium can only be absorbed into the body by entering the intestine. Milk, yoghurt, green leafy vegetables, soy products, sesame, shrimp, etc. These are all calcium supplements with high calcium content. In addition, the effect of calcium supplementation also requires attention to absorption, in addition to dietary calcium, but also often outdoor exercise, often sun, promote calcium absorption. ◠Try to improve the diet to achieve the goal of obtaining sufficient calcium from natural foods In the family's daily food, calcium is more milk, cheese, eggs, soy products, kelp, seaweed, shrimp, sesame, hawthorn, sea fish, vegetables, etc., especially milk, calcium per 100 grams of fresh milk 120 mg If you drink 250 grams of milk per person per day, you will be able to provide 300 milligrams of calcium. If you drink 500 grams of milk a day, you will be able to supply 600 milligrams of calcium. When you add 300 milligrams of calcium to other foods in your diet, you will be fully satisfied. The human needs for calcium, it is worth noting that, when eating these calcium-rich foods, should avoid excessive consumption of phosphate, oxalic acid, protein-rich foods, so as not to affect the absorption of calcium. Who needs calcium in the end? Everyone needs calcium, but most of the time, we only need to get the calcium needed through our daily diet. Those who really need additional calcium supplements are mostly people in puberty, pregnancy, menopause, and old age. Growth period There are three periods in the human body that promote physical growth. They are: 2-year-old infants; 14-18-year-old puberty, and 18-23-year-old adulthood. In these three periods, it was like planting crops. At this time, "fertilization" could be even more powerful and promote the growth of bones. Most children do not need calcium supplements from calcium products. There is only one rare disease, calcium deficiency, because these children feed on cereals all year round and eat only a single meal. Therefore, calcium intake is very low and must be supplemented with calcium. Children who do not have this disease can rely on drinking dairy products to meet calcium requirements. pregnancy Pregnancy is an important period for the formation of fetal bones and it requires pregnant women to provide adequate sources of calcium. Another situation is that the body "decomposes" and will decompose pregnant women's own calcium, causing postpartum women's low back and leg pain. Menopause Menopausal women suffer from a severe loss of calcium due to the rapid decline in estrogen after menopause. Old age As the absorption rate of calcium in middle-aged and elderly people has gradually decreased, it is easy to cause osteoporosis if calcium supplements are not paid attention. Especially women, after the age of 35, the body lost more calcium than absorbed into the body. After menopause, women suffering from osteoporosis have also suddenly increased. In order to understand the degree of calcium deficiency in the body and whether there is osteoporosis, the middle-aged and elderly people can do a bone density test. Using a dual-energy X-ray absorptiometry to perform a bone mineral density measurement, a doctor can determine whether or not he has osteoporosis.
