The causes of osteoporosis are different for different age groups. After a long-term analysis, experts have concluded that the five major factors that trigger osteoporosis in women are: dieting, beverages containing phosphate, alcohol, smoking and salt. Let’s look at the following details: a. Dieting: the most important way to lose weight is to control the diet, not knowing that this may become the fuse for osteoporosis and fractures later. A health magazine in the United States had a survey of thousands of women over 30 years old, found that 82% of them have begun to appear some degree of osteoporosis, or have the risk of osteoporosis. This is because they are usually afraid to drink milk, vegetarian diet, nutrition is not reasonable, resulting in insufficient calcium intake in the body. On the other hand, because of the fat and estrogen content, women tend to decrease the amount of estrogen with the reduction of fat, estrogen levels decline for a long time, will accelerate the loss of bone calcium. Second, phosphoric acid drinks: expert analysis, the reason for this phenomenon may be that cola contains phosphoric acid, which can lead to the loss of calcium in the body, while most other drinks do not have this substance. So experts suggest that women who are worried about osteoporosis better not drink too much cola, and pay attention to the diet to increase calcium intake to maintain bone density. The chemical composition of alcohol is ethanol, which, after entering the body, can react chemically with other inorganic substances or some organic substances to produce some new substances. These new substances can lead to the occurrence of osteoporosis. So long-term excessive alcohol consumption, will have an impact on the growth and development of bones, accelerating the loss of bone four, smoking: research shows that the reason why smoking promotes osteoporosis, the reason may be that smoking affects the formation of peak bone density, because the vast majority of smokers began smoking when they were teenagers, when it is the peak bone density formation period. Investigations have shown that smokers have some degree of bone loss in the femoral neck, ribs and vertebrae compared to their peers. And this harm is often in late middle age and old age to show. Five, salt: eat more salt will not only get high blood pressure, and will lead to osteoporosis. Experts say that eating more salt leads to osteoporosis is that the body’s treatment of excess salt is often excreted, the main sodium contained in salt, the excretion process always “pull on the companion” calcium excretion, so the result of a high-salt diet is to lead to accelerated calcium loss, of course, directly affect the quality of bone. Women in general, in order to future health to normal and reasonable diet, not alcohol, but also try to smoke less, less salt, less carbonated beverages, to avoid osteoporosis quietly come.
