健康人体内的钙,几乎99％存在于骨骼中,骨骼不仅支撑着人体,也是体内巨大的钙源。而血液中的钙又几乎99％存在于血浆中。人到了老年,各种器官组织的生理功能都在逐渐退化。钙在人体内是骨骼和牙齿的主要成分,对营养吸收有着非常重要的作用。另外,不仅对老年入骨质疏松症的预防、骨骼中钙丢失与钙吸收关系密切,而且对老年人钙营养的吸收也是极其重要的。 钙是骨代谢中不可缺少的物质,在人体内参加各种复杂的代谢过程。我们平时吃的食物是体内钙的主要的来源,当饮食中钙缺乏、过剩或是吸收不良以及其它原因,如转运、排泄等出现障碍,都会引起疾病的发生。体内钙吸收量的多少,取决于钙在肠道内的溶解度。如果降低肠道内的pH值,酸性
Almost 99% of healthy human body calcium is present in bones, which support not only the body but also the body’s huge source of calcium. And almost 99% of the blood’s calcium is present in the plasma. When people reach old age, the physiological functions of various organs and tissues are gradually degrading. Calcium in the human body is the main component of the bones and teeth, the absorption of nutrients has a very important role. In addition, not only the prevention of osteoporosis in the elderly, the loss of calcium in the skeleton and calcium absorption are closely related, but also the absorption of calcium nutrition in the elderly is extremely important. Calcium is an indispensable material in bone metabolism, in the body to participate in a variety of complex metabolic processes. We usually eat food is the main source of calcium in the body, when dietary calcium deficiency, excess or malabsorption and other reasons, such as transport, excretion and other obstacles, will cause the disease. The amount of calcium absorbed in the body, depending on the solubility of calcium in the intestine. If you reduce the intestinal pH, acidic
