Trends in dietary amino acid intake and food sources among Korean adults: data from the 2010-2022 Korea National Health and Nutrition Examination Survey.
Article in Nutrition research and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesAlthough dietary protein intake has received significant attention recently, research on dietary amino acid (AA) intake remains limited. Thus, this study aimed to estimate AA intake and food sources among Korean adults between 2010 and 2022. SUBJECTS/
methodsBased on the Korea National Health and Nutrition Examination Survey data, 69,664 adults aged 19 yrs or older were included. Essential AA (EAA), branched-chain AA (BCAA), and nonessential AA (NEAA) intakes were estimated.
resultsThe average total AA intake over the past 13 yrs was 62.1 g/day, consisting of 24.8 g/day of EAAs (11.8 g/day of BCAAs) and 37.3 g/day of NEAAs. Leucine was the most commonly consumed EAA, while glutamic acid was the most consumed NEAA. Over the study period, total AA intake remained stable. However, total AA intake relative to body weight significantly decreased, whereas intake relative to total energy and protein intake significantly increased. Similar trends were observed for EAAs, BCAAs, and NEAAs (
conclusionWhile the total absolute AA intake has remained stable over the past 13 yrs, AA density relative to protein and energy intake has increased, accompanied by changes in individual AA intake over the past decade. These findings may inform future revisions of AA intake recommendations for Koreans and facilitate further research on the association between dietary AAs and various diseases.
