Abstract Evenly distributing daily protein intake at meals has been suggested to improve muscle mass among older adults. The aim of this research is to evaluate protein intake and its distribution across three meal types (breakfast, lunch, and dinner). Nationally representative dietary intake data of adults aged 51 years and older who reported consuming breakfast, lunch, and dinner on the intake day from What We Eat in America, National Health and Nutrition Examination Survey (NHANES) 2011–2012, were analyzed.

Of men and women aged 51 years and over, 64% and 71% consumed three meal types on the intake day, respectively. Men had significantly higher mean daily protein intake than women (84.4 ± 2.33 g vs. 60.9 ± 1.21 g, p
