Macro partitioning
Moderate carbohydrate intake (50–55% of energy) is associated with the lowest all-cause mortality risk, whereas both low (<40%) and high (>70%) carbohydrate intakes are associated with increased mortality.
Aim for 50–55% of your daily calories from carbohydrates. This range is associated with the lowest risk of death in large long-term studies. Avoid going below 40% or above 70% of calories from carbs, as both extremes are linked to higher mortality.
a percentage of 50–55% energy from carbohydrate was associated with the lowest risk of mortality... both low carbohydrate consumption (<40%) and high carbohydrate consumption (>70%) conferred greater mortality risk than did moderate intake, which was consistent with a U-shaped association
Why this rating
Large prospective cohort (n=15,428) with 25-year follow-up combined with a meta-analysis of 8 cohorts (n=432,179), though observational design limits causal inference.
