Technical Abstract: By 2060, the number of adults 65 y and older is expected to double and the >=85 y segment of the population is expected to triple in the United States (US). US federal nutrition guidance is based on the premise that healthy diets contribute to delaying the onset and progression of many age-related diseases and disability. Yet, little is known about the dietary intakes or nutritional needs across the older adulthood age-span. This review aimed to identify community-based longitudinal cohorts that collected information on dietary intake of adults >=65 y in the US. Thirty-two cohorts met all inclusion criteria. We summarized information on the cohorts' design, demographics, and diet assessment. We also identified key gaps in the existing databases that, if filled, could enhance their utility to address certain research questions. This review serves as a valuable inventory of cohorts that can be leveraged to answer key questions about the diet and nutritional needs of the oldest old, which represents the fastest growing segment of the population in the US.
