人体钙元素的摄入不足是引起骨质疏松症的重要原因之一。医学研究表明,钙是构成骨矿物质的重要成分。钙占人体重量的2%,而人体内的钙99%沉积在骨骼中,是维持骨骼强度的必要物质。当体内缺钙时,骨骼中的钙即由血液输送至身体各器官,骨钙也大量地向血液中转移,以致骨矿物质大量流失,结构变为疏松、多孔,发生骨质疏松症。由于缺钙,骨强度变弱,脆 Human calcium deficiency is one of the important causes of osteoporosis. Medical research shows that calcium is an important component of bone mineral composition. Calcium accounts for 2% of the body weight, while 99% of the body’s calcium is deposited in the skeleton, which is necessary to maintain the strength of the skeleton. When the body calcium, calcium in the skeleton that is transported to the body by various organs of blood, bone calcium is also a lot of transfer to the blood, resulting in a substantial loss of bone mineral, the structure becomes loose, porous, osteoporosis occurs. Due to calcium deficiency, bone strength weakened, crisp
