一个新的生命——胎儿的生长是在遗传因子和内分泌的控制下进行的。身体的基本单位是细胞,每一个细胞的增长和复制,都要经过复杂的合成过程。它需要热量、蛋白质和许多种类的辅酶类的物质,来推进和完成这一工作。而对于胎儿来说,这些营养物质的唯一来源是母体的供给。如果孕妇缺乏营养,胎儿的代谢物质来源不足,生长就要发生障碍。因此,要使胎儿长得健壮,首先要保证孕妇营养充足。所谓“母壮儿肥”也就是这个道理。
A new life - fetal growth is under the control of genetic factors and endocrine. The body’s basic unit is cells, each cell growth and replication, have to go through a complex synthesis process. It requires heat, protein and many kinds of coenzymes to advance and accomplish this work. For the fetus, the only source of these nutrients is the maternal supply. If pregnant women lack nutrients, lack of fetal sources of metabolites, growth is impeded. Therefore, to make the fetus grow robust, we must first ensure adequate nutrition in pregnant women. The so-called “mother and son fat” is the truth.
