虽然美国的蛋白质摄入量被广泛认为是足够的，但人们已经注意到老年人的建议或摄入模式可能不足。这项研究的目的是更新和扩大对美国老年人蛋白质摄入量和充足性的估计，并额外关注动物源蛋白质的贡献。数据来自2005-2006年国家健康与营养调查、膳食研究食品与营养数据库和美国农业部标准参考数据集中的1,768名51岁及以上的成年人。摄入量不足的估计值范围为= 71岁，这取决于是否使用调整后的体重或实际体重来计算每公斤体重的蛋白质克数。在同一组中，平均日常蛋白质摄入量分别为94 +/- 22 g/天和56 +/- 13 g/天，其中15.3%+/- 2.3%和15.4%+/- 2.4%的能量来自蛋白质。平均而言，动物来源提供了>60%的蛋白质摄入量。在以能量摄入、年龄、性别、种族和教育程度为协变量的回归模型中，动物源蛋白质百分比预测了蛋白质摄入量和满足推荐膳食摄入量的几率（P
Although protein intakes in the United States are widely regarded as adequate, attention has been given to potential inadequacy of recommendations or patterns of intake in older adults. The objectives of this research were to update and expand estimates of protein intake and adequacy in older US adults, with additional focus on contributions of animal source protein. Data were obtained from 1,768 adults aged 51 years and older in the National Health and Nutrition Examination Survey 2005-2006, the Food and Nutrient Database for Dietary Studies, and US Department of Agriculture Standard Reference datasets. Estimates of inadequate intakes ranged from = 71 years, depending on whether adjusted or actual body Weights were used to calculate grams of protein per kilogram of body weight. Mean usual protein intakes were 94 +/- 22 giddy and 56 +/- 13 g/day in those same groups, with 15.3%+/- 2.3% and 15.4%+/- 2.4% of energy from protein. Animal sources provided >60% of protein intake, on average. In regression models with energy intake, age, sex, ethnicity, and education as covariables, percent protein from animal sources predicted protein intake and odds of meeting the Recommended Dietary Allowances (P
