- Abstract
- Background: Increasing obesity rates are related to energy intake with carbohydrate and fat ratio. Using Korean National Health and Nutrition Examination Survey 2007-2017, we examined the hypothesis that the fat intake and food sources of dietary fats had changed over the last 10 years according to gender and obesity status in adult population >= 19 years. Methods: The food intake of each participant was collected by the 24-hour recall method, and nutrient intake including different fatty acids was calculated. The fatty acid intakes from 7 food groups were determined according to gender and obesity status. Results: Body mass index increased in both genders of the obese group last decade, but it decreased in the normal-weight group. In men, energy intake was higher in the obese group than in the lean group, but the opposite trend was shown in women. Total fat intake including various fatty acids continuously and sharply increased in both men and women until 2016, then slightly declined only in men. The source of saturated fatty acid (SFA) intake was mainly from the animal food group in men and women regardless of obese status, and SFA and monounsaturated fatty acid from the animal food group gradually increased over time in both genders. N-3 fatty acid intake markedly decreased from fish and crabs and increased from sauces and nuts regardless of genders and the obese status from 2008 to 2017. Polyunsaturated fatty acid and N-6 fatty acid intake increased from bread, cookies, sauces, and nuts regardless of genders and obesity status. Conclusion: Fat intake was higher in obese men but this trend was opposite in women. The N-3 fatty acid intake from seafood should increase, and the fat composition in sauce needs to be modulated to increase N-3 fatty acids.
