Macro partitioning
Global average total protein intake (78.2 g/day) exceeds the minimum requirement for health in all surveyed countries, with national means never falling below 46 g/day, indicating that protein deficiency is not a widespread global issue in terms of quantity.
You do not need to worry about global protein shortages or your personal intake being critically low if you eat a standard diet. The global average is 78g/day, and even the lowest-consuming nations average 46g/day, which is sufficient. Focus on the source (animal vs. plant) and overall diet quality rather than fearing protein deficiency.
Mean national total protein intake was ≥46 g/day in all 185 countries.
Why this rating
Large-scale Bayesian hierarchical model using 1137 survey-years from 185 countries provides robust population-level data.
