Dietary pattern, inflammation, and incidence of type 2 diabetes in women.
BACKGROUND Inflammation is considered a key mechanism leading to type 2 diabetes , but dietary exposures that lead to inflammation and diabetes are largely unknown . OBJECTIVE Our objective was to investigate the relation between a dietary pattern associated with biomarkers of inflammation and the incidence of type 2 diabetes . DESIGN We conducted a nested case-control study of 656 cases of type 2 diabetes and 694 controls among women in the Nurses ' Health Study and 2 prospect i ve cohort studies of 35,340 women in the Nurses ' Health Study and 89,311 women in the Nurses ' Health Study II who were followed for incident diabetes . RESULTS Through the use of reduced rank regression , we identified a dietary pattern that was strongly related to inflammatory markers in the nested case-control study . This pattern , which was high in sugar-sweetened soft drinks , refined grains , diet soft drinks , and processed meat but low in wine , coffee , cruciferous vegetables , and yellow vegetables , was associated with an increased risk of diabetes ( multivariate-adjusted odds ratio comparing extreme quintiles : 3.09 ; 95 % CI : 1.99 , 4.79 ) . We identified 1517 incident cases of confirmed type 2 diabetes in the Nurses ' Health Study ( 458,991 person-years ) and 724 incident cases in the Nurses ' Health Study II ( 701,155 person-years ) . After adjustment for body mass index and other potential lifestyle confounders , the relative risks comparing extreme quintiles of the pattern were 2.56 ( 95 % CI : 2.10 , 3.12 ; P for trend < 0.001 ) in the Nurses ' Health Study and 2.93 ( 95 % CI : 2.18 , 3.92 ; P for trend < 0.001 ) in the Nurses ' Health Study II . CONCLUSION The dietary pattern identified may increase chronic inflammation and raise the risk of developing type 2 diabetes
