What do these findings mean?
T2D
Adherence to the Mediterranean diet may be more beneficial for the primary prevention of T2D than previously estimated from observational dietary studies.Even small upward differences in objectively measured Mediterranean diet may be associated with a sizeable reduction of the risk of T2D at the population level.Causal interpretation of these findings is limited by potential measurement error in nutritional biomarkers, unclear specificity of the biomarker score to the Mediterranean diet, and possible residual confounding.
