Background: Type 2 diabetes mellitus (T2DM) is a multidimensional consequence of environmental and genetic factors. Cholesteryl ester transfer protein (CETP) Taq1B polymorphism has been reported as a main predictor of dyslipidaemia, comprising an important complication in persons with T2DM. However, diet could affect T2DM patients metabolic health. Methods: We investigated the combination of gene–diet effects on some metabolic biomarkers. In our cross‐sectional study, blood samples of 220 patients were collected. Dietary indices (healthy eating index, dietary quality index and dietary phytochemical index) were obtained from a validated semi‐quantitative food frequency questionnaire. CETP Taq1B polymorphism was genotyped by a polymerase chain reaction‐restriction fragment polymorphism method. Data were analysed by analysis of covariance. Results: The interaction between the CETP Taq1B polymorphism and dietary indices on low density lipoprotein/high density lipoprotein was significant (p < 0.001 both crude and adjusted models). In addition, the interaction between polymorphism and dietary quality index on total antioxidant capacity (p = 0.004 crude model, p = 0.005 after adjusting) and pentraxin 3 (p = 0.01 both crude and adjusted models) was significant. Also, the interaction between polymorphism and healthy eating index on waist circumference (p = 0.005 both crude and adjusted models) and dietary phytochemical index on interleukin‐18 (p = 0.03 crude model) was significant. Conclusions: Our results indicated the effect of CETP Taq1B polymorphism on some inflammatory and anthropometrics markers (total antioxidant capacity, pentraxin 3, interleukin‐18, low density lipoprotein/high density lipoprotein and waist circumference) with high and low adherence to dietary incides. Highlights: The role of different genotypes of CETP Taq1b on lipid profile is undeniable.CETP Taq1b polymorphism might change the effect of adherence to dietary patterns.The interaction between CETP Taq1b genotypes and dietary indices on metabolic biomarkers could be different in people with T2DM, even when they have healthy adherence to dietary patterns.Beside metabolic biomarkers such as TAC, PTX3, IL‐18, central obesity and lipid profile might be under the effect of the interaction between CETP Taq1b genotypes and dietary indices in T2DM individuals.
