Dietary intakes were evaluated using a valid and reliable semi-quantitative food frequency questionnaire. Biochemical variables and anthropometrics were evaluated at baseline and follow-up examinations. Multivariate Cox proportional hazard regression models were used to estimate the development of type 2 diabetes mellitus (T2DM) in relation to total intake of polyphenol and its subclasses (flavonoids, phenolic acids, stilbenes, and lignans).Results: This study was conducted on 2,882 men and 3,665 women, aged 41.3± 14.6 and 39.0± 13.4 years, respectively. The number of participants with the new-onset T2DM was 253. Mean intake of total polyphenol was 346± 245 mg/1000 kcal. Risk of type 2 diabetes decreased from quartiles 1 to 4 for total polyphenols (HR: 1.00, 0.37, 0.61, 0.50, Ptrend< 0.01), phenolic acids (HR: 1.00, 0.57, 0.49, 0.45, Ptrend< 0.01), and lignans (HR: 1.00, 0.67, 0.61, 0.60, Ptrend< 0.01), whereas non-significant results were found for flavonoids and stilbenes. This study suggests an inverse association between total intake of polyphenols, phenolic acids, and lignin, and the risk of T2DM.Conclusion: These results emphasize the potential protective role of polyphenol rich food groups (especially fruits and vegetables) in the prevention of T2DM.Keywords: polyphenols, flavonoids, phenolic acids, stilbenes, lignans, diabetes |
