They don't call protein one of "the building blocks of life" for nothing. This macronutrient makes up the major component of all our cells and provides the essential amino acids that keep our bodies up and running. Problem is, some of us aren't getting as much of it as we should be. 人们将蛋白质称作"生命的基石"之一并不是毫无来由的。这一常量营养素是人体所有细胞的主要成分，提供人体所需的氨基酸（保持身体正常运转）。问题是，有些人摄入的蛋白质还不够。 A true protein deficiency is very rare in the United States-though it can be seen in people who have anorexia, cancer, or, in the case of severe malnutrition, undiagnosed Crohn's disease-but sometimes, vegans or people who follow a raw food diet could find themselves running a little low, says Leslie Bonci, a nutritionist, owner of Active Eating Advice, and nutrition consultant for the Kansas City Chiefs. 在美国，真正缺乏蛋白质的案例十分罕见--尽管厌食症、癌症或严重营养不良、未确诊的克罗恩病的患者会发生这一情况--但有时候，素食者或生吃食物的人群也会发现自己摄入的蛋白质含量较低，Active Eating Advice的所有者、Kansas City Chiefs的营养顾问莱斯利·邦思营养师说道。 |
