This study was performed to construct a fatty acids database (DB) for use with a nationally representative population survey, the Korea National Health and Nutrition Survey (KNHANES). The DB was designed as multi level from 0 to 3. Level 0 DBs were food composition data sources, which were graded according to the reliability and validity of the data sources and compiled to level 1 DB. The coverage of individual fatty acids of level 1 DB was C14:0, C16:0, C18:0, C18:1, C18:2 n‐6, C18:3n‐3(α), C20:5 n‐3(EPA), C22:6 n‐3(DHA), SFA, MUFA, and PUFA (n‐3, n‐6, n‐9). Food list of level 2 DB consisted of 5,144 foods used for dietary analysis in KNHANES. The fatty acid composition of level 2 DB was filled with analytical values of food items from level 1 DB. One analytical value for each food item was selected according to quality of data sources and priority guideline in data selection. Missing values were replaced with calculated or imputed values based on the analytical values of similar food items from level 1 DB. Level 2 DB comprised of 1,543 analytical values, 2,589 calculated values and 1,012 imputed values. Fatty acid intake was calculated with food consumption data in 2010 and 2011 KNHANES and level 3 DB was compiled with fatty acids composition of 2,112 food items used in the calculation. Mean intake levels of total fatty acid and saturated fatty acid were 38.3g/day and 12.7g/day, respectively. SFA: MUFA: PUFA was 1.1: 1.2: 1. Estimation of fatty acid intakes with newly developed fatty acids DB based on national survey data will shed light on the establishment of nutrition policy solving related public health concerns.
