Tacos, burritos, and other Mexican foods are popular dietary choices in the U.S. (see definition of “Mexican food” on page 8). Approximately one out of every ten U.S. restaurants serve Mexican food (1), and a majority of the U.S. population used Mexican food/ingredients in 2020 (2). However, few details are known about their consumption. The purpose of this report is to describe intake of select highly reported Mexican foods by U.S. adults 20 years and older: who consumes them, what types of foods are consumed, and their contributions to energy and nutrient intake. This analysis is based on one day of dietary intake data from What We Eat in America (WWEIA), National Health and Nutrition Examination Survey (NHANES) 2017 – March 2020. A complementary report (Dietary Data Brief No. 63) describes Mexican food consumption by U.S. children 2-19 years.
