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 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
