Macro partitioning
In Korean adults, an energy intake distribution of 50–60% carbohydrates, 30–40% fat, and 20–30% protein is associated with the lowest all-cause mortality risk.
For Korean adults, aiming for 50-60% of calories from carbohydrates, 30-40% from fat, and 20-30% from protein is associated with the longest life expectancy. This suggests revising current dietary guidelines to lower the recommended carbohydrate range and potentially increase healthy fat intake within this optimal window.
Time to exceed 1% of the all-cause mortality rate was longest in participants with 50–60% carbohydrate, 30–40% fat, and 20–30% protein intake.
Why this rating
Large prospective cohort study (n=42,192) with long follow-up and adjustment for confounders, but observational design limits causal inference.
