Abstract：
Dietary protein intake is vital to life. Here we sought to characterize dietary sources of protein in eight Latin American countries. Survey data were collected for Estudio Latinoamericano de Nutrición y Salud (ELANS); participants were from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela (n = 9218, 15-65 years old). The primary aim of this analysis was to quantify per-person daily protein consumption by country and sociodemographic factors. Secondary aims: to quantify proportional intake of proteins by source, amount and processing, and to determine the adequacy of protein/essential amino acid intake. Younger groups (adolescents 15-19 years, adults 20-33 years) had the highest intake of proteins; middle-aged adults (34-49 years) had a lower intake, and older adults (50-65 years) had a strikingly lower intake. Protein consumption was higher in men than women. Animal proteins comprised nearly 70% of total daily protein intake in Argentina and Venezuela, contrasting with <60% in Peru, Chile, and Costa Rica. Brazil and Venezuela showed the highest protein intake within the highest education level. The higher the socioeconomic level, the higher the protein intake, except for Argentina, Chile, and Peru. Proportional intake of animal- and plant-based protein generally reflected the food availability by country. This study presents a pre-pandemic regional baseline and offers a perspective for future studies of changes related to government policies, climate, and dietary practices.
摘要：
膳食蛋白质的摄入对生命至关重要。在这里，我们试图描述八个拉丁美洲国家蛋白质的饮食来源。调查数据是为拉丁美洲的EstudioLatinoamericanodeNutriciónySalud（ELANS）收集的；参与者来自阿根廷，巴西,智利,哥伦比亚,哥斯达黎加,厄瓜多尔,秘鲁,委内瑞拉（n=9218，15-65岁）。该分析的主要目的是按国家和社会人口统计学因素量化每人每天的蛋白质消费量。次要目标：量化按来源比例摄入的蛋白质，数量和加工，并确定蛋白质/必需氨基酸摄入量的充足性。年轻群体（青少年15-19岁，20-33岁的成年人）的蛋白质摄入量最高；中年人（34-49岁）的摄入量较低，和老年人（50-65岁）的摄入量显着降低。男性的蛋白质消耗高于女性。在阿根廷和委内瑞拉，动物蛋白质占每日蛋白质摄入量的近70%。与秘鲁的60%相比，智利,哥斯达黎加。巴西和委内瑞拉在最高教育水平下的蛋白质摄入量最高。社会经济水平越高，蛋白质摄入量越高，除了阿根廷,智利,秘鲁。动物和植物性蛋白质的比例摄入量通常反映了各国的粮食供应。这项研究提供了大流行前的区域基线，并为未来研究与政府政策有关的变化提供了一个视角，气候,和饮食习惯。
