妊娠始终伴随着钙和骨的新陈代谢 ,以及矿物质在骨骼内的变化。此变化与母亲为了胎儿生长和产乳而发生的骨骼吸收和转移钙是一致的。哺乳可降低骨矿物的含量 ,增加骨的更新 ,减少钙在尿液中的排泄。研究表明 ,既使对那些钙摄入量较低的妇女 ,在哺乳期增补钙摄入量 ,不能影响骨反应 ,也不会增加母乳中钙的分泌。孕期使用含钙食物有助孕妇的健康、乳汁的钙含量 ,并控制胎儿骨骼矿物质的变化及其血压 Pregnancy is always accompanied by calcium and bone metabolism, as well as minerals in the bone changes. This change is consistent with the bone absorption and transfer of calcium by the mother for fetal growth and milk production. Breastfeeding can reduce bone mineral content, increase bone regeneration, reduce calcium excretion in the urine. Studies have shown that even in women with low calcium intake, calcium intake during lactation does not affect the bone response, it does not increase calcium secretion in breast milk. Pregnancy using calcium-containing foods helps the health of pregnant women, the milk’s calcium content, and controls changes in fetal bone mineral and its blood pressure
