Nowadays, people know that middle-aged and elderly people, especially the modern “white-collar” sitting in the office for a long time will often occur osteoporosis, that is, the so-called “calcium deficiency”. So they desperately “calcium supplement” to take a lot of calcium supplements. And also justifiably said: “What is lacking, what to make up for” well! Do not realize that now people have entered a “calcium” of the misunderstanding, blind calcium supplementation not only can not improve osteoporosis, and will even increase the risk of other diseases. Why? Look at the role of calcium in the human body and its metabolic process: Calcium is the main component of the human body’s bones, bones is also the body’s largest “calcium bank”. So where does the calcium in the “calcium bank” come from? Since the “calcium bank” in the “but calcium”, that calcium are lost to where? Let’s look at the metabolic process of calcium in the human body: Calcium into the process: intake (eat into) synthetic state of calcium (such as calcium hydrochloride, calcium sulfate, calcium gluconate and other calcium salts) → into the intestinal tract will be the decomposition of synthetic calcium (calcium ions) → absorption (calcium ions into the blood circulatory system) → ionic calcium transfer into the bones (in the bones to re-synthesize calcium salts); calcium out of the process: the decomposition of synthetic calcium in the skeleton → calcium Ion release (into the circulatory system) → ionic calcium transfer (into the urinary system) → excretion (synthesized calcium urate). Characteristics of calcium metabolism: Entry: synthetic state (ingestion) → ionic state (transfer in blood) → synthetic state (bone storage) Exit: synthetic state (bone breakdown) → ionic state (transfer in blood) → synthetic state (urinary excretion) As you can see, calcium enters and exits the body in 3 stages. Whether calcium enters or exits the body, it passes through the blood system, where it exists in an ionized state in the circulatory system. The ionized calcium that enters the blood vessels is called “blood calcium”. High blood calcium is harmful: the ionic state of calcium will combine with the acid in the blood to form calcium salts, which will be deposited on the walls of the blood vessels, leading to “calcification” of the blood vessels, which is often referred to as atherosclerosis. Atherosclerosis is an important foundation for serious cardiovascular diseases such as cerebral thrombosis and coronary heart disease. In addition, when excessive calcium ions are excreted from the kidneys, they combine with uric acid or oxalic acid in the urine to form calcium urate and calcium oxalate, which are kidney stones! Also, osteoporosis due to the bones of a large number of calcium “off” to the blood, from the bones run out of calcium is not lost to the body, but from the bones of the “off” to the blood, so osteoporosis blood calcium itself is high, so osteoporosis patients are in fact the “osteoporosis”. Therefore, osteoporosis patients have high calcium in their blood, so osteoporosis patients are actually patients with “high blood calcium”! At this time, if you insist on taking calcium preparations, the calcium that cannot be absorbed by the bones will be “blocked” in the circulatory system, which will easily lead to a series of other diseases caused by high blood calcium. Therefore, do not blindly “calcium supplement”!
