Serum triglyceride levels are associated with metabolic disorders; however, it remains unclear whether the fatty acid (FA) composition of triglycerides is also changed. Although there were no differences in circulating triglyceride levels between normoglycaemic-normoinsulinaemic and hyperglycaemic-hyperinsulinaemic men, inspection of individual
