There are a lot of people who are deficient in calcium, and usually if you don’t pay much attention to the combination of diet, then you may be deficient in calcium. What are the causes of calcium deficiency? This is a problem that many people are concerned about, we should understand. 1, dietary causes of calcium deficiency (1) excessive salt intake The main component of salt is NaCL (sodium chloride), and consume too much salt, that is, sodium chloride intake is too much, will make the human body discharged in the urine calcium ions increase, that is, cause calcium loss and thus cause calcium deficiency. So in the daily diet, to do low-salt diet, daily salt intake is good less than 3 grams. (2) excessive intake of sugar The main component of sweets is carbohydrates, unlike staple foods, staple foods, although the main component is also carbohydrates, but the content of sweets is higher, the calorie is also relatively higher, so sweets eat more easy to get fat, and sweets don’t contain vitamins and trace elements, so the intake of sweets, the human body should be relatively consumed reserves of vitamins and trace elements, which include calcium. Calcium is included. Therefore, if you eat too much sweets, it is easy to cause calcium deficiency and tooth decay. (3) Drinking too much coffee Adults daily recommended caffeine intake of 300 milligrams, and a cup of coffee on the market contains 150-200 milligrams of caffeine, and many office workers, especially those who work under pressure and often work overtime, may be like according to the three meals a day as 3 cups of coffee a day, and if they work overtime, they may also want to add a cup of coffee, which is absolutely the caffeine intake. Caffeine can lead to calcium loss. Therefore, people who drink too much coffee every day and do so for a long time will lose calcium in their bodies, and the calcium taken from food every day will not be easily absorbed by the human body, which is likely to cause osteoporosis. (1) Postmenopausal women Women menopause is a process that must be experienced, also known as menopause, menopausal women’s body estrogen began to reduce the calcium inside the bone is easy to lose, so menopausal women are especially prone to osteoporosis, it is necessary to pay attention to the calcium of the population. (2) Diabetic patients Diabetic patients have low levels of insulin in their blood, and insulin can stimulate the body to form collagen, which can help bones store calcium, so diabetic patients are also more prone to calcium deficiency, which can lead to osteoporosis. (3) Insufficient generation of vitamin D. Calcium intake from the diet only ensures the intake of calcium, but the body does not necessarily absorb it, while vitamin D can promote the body’s absorption of calcium. The human body itself is able to synthesize vitamin D, but if their own generation of vitamin D is insufficient, it may also cause calcium deficiency, and smoking and alcoholism and other bad habits may cause their own vitamin D generation is insufficient. 3, other reasons (1) insufficient light sunlight on the skin, can generate vitamin D in the human body, but there is a saying called “a white cover three ugly”, and now people are white for the beauty, refused to sunbathing, that will be tanned skin, see the solar energy does not go out, really want to go out, but also armed with a hiding the sun to go out, this is likely to cause the sun to go out. The sun to go out, this is likely to cause insufficient light, which leads to their own synthesis of vitamin D is insufficient, causing calcium deficiency. (2) lack of exercise Exercise does not necessarily accelerate the absorption of calcium, but more exercise and exercise can improve the density of human bones, thereby reducing bone loss, indirectly also reduces the loss of calcium, and lack of exercise is likely to trigger calcium deficiency.
