Objectives: This study evaluated dietary intakes of total fat and fatty acids among the Korean adult population.
Methods: This cross-sectional study used the 2016-2017 Korea National Health and Nutrition Examination Survey data. A total of 10,772 subjects aged ≥19 y for which dietary data were available were selected. Data pertaining to energy and nutrient intakes were obtained by a 24-h recall method. Total fat and fatty acids intakes were evaluated based on the Acceptable Macronutrient Distribution Ranges (AMDR) of 2015 Dietary Reference Intakes for Koreans by sex and age groups. All statistical analyses accounted for the complex sampling design effect and sampling weights.
Results: The mean intakes of energy and total fat were 1,952 kcal (95% CI: 1928-1977) and 46.1 g (45.2-47.1), respectively, and about 21% of the energy was obtained from fat in this study population (21.7% in men and 20.2% in women). The mean percentages of energy from saturated, monounsaturated, and polyunsaturated fatty acids were 6.4%, 6.7%, and 5.2%, respectively. About 18% of adults exceeded the AMDR for fat (30% of energy), whereas 37.6% exceeded the AMDR for saturated fatty acids (7% of energy). The proportions of subjects who consumed more than the AMDR for fat and saturated fatty acids decreased across age groups in both sexes. Among young adults (19-29 y), about 63% of the subjects obtained ≥7% of their energy from saturated fatty acids. About 61% of older adults obtained less than 15% of their energy from total fat.
Conclusions: Increased intake of fat energy was prominent in saturated fatty acids. Our findings suggest current information on total fat and fatty acids intakes in Korean adults and can be used to provide dietary guidelines for the improvement of public health.
