The 2015 Dietary Guidelines for Americans recommends that individuals should minimize their dietary cholesterol intake. However, current dietary cholesterol intake and its food sources have not been well-characterized. We examined dietary cholesterol intake by age, sex, race, and food sources using 24-h dietary recall data from a nationally representative sample of 5047 adults aged 20 years or older who participated in NHANES (2013-2014 survey cycle). We also reported trends in cholesterol intake across the past seven NHANES surveys. Mean dietary cholesterol intake was 293 mg/day (348 mg/day for men and 242 mg/day for women) in the 2013-2014 survey cycle; 39% of adults had dietary cholesterol intake above 300 mg/day (46% for men and 28% for women). Meat, eggs, grain products, and milk were the highest four food sources of cholesterol, contributing to 96% of the total consumption. Both average cholesterol intake and food source varied by age, sex, and race (each p < 0.05). Mean cholesterol intake of the overall population had been relatively constant at similar to 290 mg/day from 2001-2002 to 2013-2014 (p-trend = 0.98). These results should inform public health efforts in implementing dietary guidelines and tailoring dietary recommendations.
