Macro partitioning
A higher variety score of dietary protein sources (consuming appropriate quantities from more of the eight major sources: grains, meat, poultry, fish, egg, legumes) is inversely associated with the risk of new-onset diabetes.
To lower your risk of type 2 diabetes, aim to include a variety of protein sources in your diet rather than relying on just one or two. The study suggests that consuming appropriate amounts from a mix of grains, legumes, fish, poultry, and eggs is associated with a significantly lower risk of developing diabetes compared to a diet with fewer protein sources. You do not need to eliminate any specific source, but rather ensure your diet includes a broad spectrum of these foods.
a significantly lower risk of new-onset diabetes was found in those with a higher variety score of protein sources (per score increment; HR, 0.69; 95%CI, 0.65–0.72).
Why this rating
Large-scale prospective cohort (n=16,260) with long follow-up (median 9 years) and rigorous adjustment for confounders.

More from this paper
- 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).Good
- Specific protein sources have non-linear associations with diabetes risk: fish and legumes show inverse J/L-shaped associations (lower risk with higher intake), while red meat and poultry show J/U-shaped associations (increased risk at high intakes).Good
