Nutritional risk assessment using estimated usual nutrient intake in Korean adults: analysis of the 8th (2019–2021) Korea National Health and Nutrition Examination Survey data

Estimating the usual nutrient intake offers a more robust and realistic nutritional risk assessment than using the one-day dietary recall data as it stands. This study revealed disparities in nutritional intake according to gender and age, and highlighted the dual role of DSs. Public health strategies should support food-based nutrient adequacy before promoting DS use and provide targeted interventions for vulnerable groups.
