蛋白摄入主要通过对肝脏、软骨、下丘脑 -生长激素 (GH) -胰岛素样生长因子 (IGF)系统 ,以及体内某些主要激素影响胰岛素样生长因子 -1的产生和功能 ,并对骨的代谢及峰骨值发挥调节作用。低蛋白摄入不仅容易造成老年骨质疏松 ,还使骨质疏松性骨折发生率上升 ,对骨折后的临床恢复过程也产生负面影响。因此 ,蛋白质在老年骨质疏松的发病机理中起重要作用 Protein intake affects insulin-like growth factor-1 production and function mainly by the liver, cartilage, hypothalamic-growth hormone (GH) -insulin-like growth factor (IGF) system, and certain major hormones in the body, Metabolic and peak bone value play a regulatory role. Low protein intake not only easily lead to osteoporosis in the elderly, but also to increase the incidence of osteoporotic fractures, fractures after the clinical recovery process also had a negative impact. Therefore, proteins play an important role in the pathogenesis of senile osteoporosis
