Higher circulating levels of trans-palmitoleic acid (trans-16:1n-7), an exogenous fatty acid derived primarily from dairy fat, are associated with a significantly lower incidence of type 2 diabetes and improved metabolic risk factors, including lower insulin resistance and triglycerides.

Higher levels of trans-palmitoleic acid, a fatty acid found in dairy products, are linked to a lower risk of developing type 2 diabetes and better metabolic health. While this is an observational finding, it suggests that including whole-fat dairy as part of a balanced diet may be associated with these benefits, distinct from industrial trans fats.

Trans-palmitoleate was also associated with a substantially lower incidence of diabetes, with multivariate hazard ratios of 0.41 (95% CI, 0.27 to 0.64) and 0.38 (CI, 0.24 to 0.62) in quintiles 4 and 5 versus quintile 1 (P for trend < 0.001).
