2025 KDRIs: what changed in Korea's nutrient reference values
Korea's 2025 Dietary Reference Intakes (한국인 영양소 섭취기준): carbohydrate range down to 50–65%, protein up to 10–20%, first-ever choline values, ~20 nutrients revised, and reworked sugar guidance — with every change sourced.

🇰🇷 The 2025 KDRIs land: less carbohydrate, more protein, choline debuts
December 31, 2025 · South Korea · KDRIs
South Korea's Ministry of Health and Welfare released the 2025 Korean Dietary Reference Intakes (한국인 영양소 섭취기준) on 31 December 2025 — the second five-year revision since the standards were enacted nationally in 2015, developed with the Korean Nutrition Society.
The acceptable carbohydrate range drops from 55–65% of energy to 50–65%, and protein rises from 7–20% to 10–20% (fat stays 15–30%). Choline gets Korean reference values for the first time, and around 20 nutrients were revised, including dietary fiber, vitamin B6, calcium, phosphorus, and sodium.
Sugar guidance was reworked: total sugars at or below 20% of energy, added sugars below 10%, with new advice to minimize sugary-drink intake.
What it means: Korea's official targets now say relatively less carbohydrate and more protein. Our Korean guidelines pages now document the 2025 standards; the calculator's serving patterns stay 2020-edition until the 활용편 ships.

The full analysis
The Korean Dietary Reference Intakes are the country's official nutrient targets — the Korean counterpart of the US DRIs — enacted nationally in 2015 and revised on a five-year cycle by the Ministry of Health and Welfare with the Korean Nutrition Society. The 2025 edition, released 31 December 2025 after a three-year revision project, is the second full revision, following 2020. It covers 41 nutrients.
The headline is the macronutrient balance. The acceptable range for carbohydrate drops from 55–65% of energy to 50–65%, and protein rises from 7–20% to 10–20%, while fat stays at 15–30%. Korea's official targets now leave meaningfully more room for protein-forward eating — a directional echo of what the 2025–2030 US guidelines did the same winter, arrived at independently.
Choline gets Korean reference values for the first time — an adequate intake of 480 mg for men and 390 mg for women, with upper limits of 3,000 and 2,500 mg. Around twenty nutrients were revised in total, among them dietary fiber, iron, vitamin B6, calcium, phosphorus, and sodium. One continuity point: the estimated energy requirement (EER) still uses the unchanged IOM-2005 equation.
Sodium was restructured by age. The chronic-disease-risk-reduction (CDRR) value stays 2,300 mg/day for adults 19–64, but the 2025 edition splits older adults for the first time: 1,900 mg/day for ages 65–74 (lowered) and 1,800 mg/day for 75 and older (raised). Menus and worksheets that used a single adult sodium ceiling now need two.
Sugar guidance was restructured: total sugars at or below 20% of energy (the 2020 edition phrased this as a 10–20% range), added sugars below 10%, and — new as explicit advice — minimizing sugary-drink intake.
What changed — and what hasn't yet: the 2025 release publishes the nutrient standards but explicitly defers the revised meal patterns (권장식사패턴) and the 식품구성자전거 (Food Balance Bicycle) to a forthcoming separate application volume (활용편). Until that publishes, the 2020-edition patterns remain Korea's current published serving patterns — there is no 2025 serving pattern to adopt yet.
What it means for this site: our Korean dietary guidelines pages now document the 2025 nutrient standards, with edition provenance stated on every surface. The Korea calculator's serving patterns stay the 2020 edition — the patterns Korea itself has not yet reissued — and we'll adopt the 2025 patterns the moment the 활용편 ships. We never silently swap reference values; the primary sources below carry the full 2025 tables today.
For educators: the practical classroom takeaway is the carbohydrate floor moving from 55% to 50% and protein's floor moving from 7% to 10% — worksheets that quote the 2020 ranges are now one edition behind.
