Abstract
Racial/ethnic and socioeconomic disparities in obesity and other chronic diseases are constant features of the US population and warrant continuous research on the linkage and causation between social demographic factors and distant health outcomes, and on related interventions. Many believe that the racial/ethnic and socioeconomic disparity in dietary intake is an important intermediate factor contributing to the disparities in obesity and other lifestyle-related diseases (1). Kirkpatrick and colleagues (2) provide some new evidence on differences in food group-based dietary intakes across race/ethnicity and income groups in terms of meeting the US Department of Agriculture (USDA) dietary recommendations (3).
