普遍认为,儿童处于生长发育阶段,需要补钙。但是,近些年来研究结果表明,老年人的多种疾病与缺钙有关,也应注意补充钙。 钙在人体中的含量最丰富,总量超过1000克,其中90％存在于骨骼中,仅10％左右分布于血液及各种软组织中。可见,骨骼是钙的储存室。钙在神经、肌肉的应激、神经冲动传递、心脏跳动节律的维持,血液凝固等方面,都起着重要作用。 It is generally believed that children are in the stage of growth and development and need calcium supplement. However, the results of recent studies show that various diseases in the elderly are associated with calcium deficiency, and calcium supplementation should also be noted. Calcium in the human body is the most abundant, with a total amount of more than 1000 grams, of which 90% exist in the bones, only about 10% distributed in the blood and various soft tissues. Visible, bone is calcium storage room. Calcium plays an important role in nerves, muscle stress, nerve impulse transmission, maintenance of cardiac rhythm and blood coagulation.
