Macro partitioning
Total protein intake has a U-shaped association with diabetes risk, where both very low (<10.6% of energy) and very high (≥14.0% of energy) intakes are associated with higher risk compared to moderate intake (10.6-14.0% of energy).
Avoid both very low and very high total protein intakes. The study suggests that getting 10.6% to 14.0% of your daily calories from protein is associated with the lowest risk of developing diabetes. This means you should neither severely restrict protein nor consume excessive amounts, but rather aim for a moderate level.
Overall, there was a U-shaped association between the percentage energy from dietary total protein intake and new-onset diabetes... significantly higher risks of new-onset diabetes were found in participants in the first quintile (<10.6% of energy from total protein... and the fifth quintile (≥14.0% of energy...)
Why this rating
Large-scale prospective cohort with rigorous statistical modeling (restricted cubic splines).
