Background Optimum nutrition has an integral role in glycemic control of diabetic patients. In this study, we intend to explore the frequency of food group/item consumption and its association with the risk of poor glycemic control (Hb A1c >7%) among type 2 diabetes (T2D) patients in the United Arab Emirates (UAE), since there are no data available in this region. Methods In this retrospective cross-sectional study, data on frequency of food group/item consumption of 843 T2D patients aged ≥18 years were collected from records documented by dietitians in a tertiary care center in the UAE. Results The trends of food consumption demonstrate that one-third of the participants consumed all five major food groups, and 10% adhered to the recommended “MyPlate” meal pattern with the optimum mix of food groups. Univariate analysis indicated that participants who adhered to the MyPlate meal pattern presented lower Hb A1c ( β =−0.78, 95% CI −1.22, −0.25; P <0.01). Daily intake of fresh fruit was shown to be protective ( β =−0.64, 95% CI −1.26, −0.04; P =0.04) while fruit juice intake >1 time/day increased the risk of poor glycemic control ( β =1.53, 95% CI 0.72, 2.35; P <0.001). Multiple logistic regression models (area under the receiver operating characteristics curve =0.67) showed consumption of fizzy drinks and fast food ≥1 time/week increased the odds of poor glycemic control by 2.05 (95% CI 1.16, 3.68; P =0.01) and 1.83 (95% CI 1.02, 3.3 P =0.04), respectively, while fresh fruit consumption indicated a clinically relevant protective effect  (OR=0.65, 95% CI 0.23, 1.79; P =0.4). Conclusion Consuming food such as fizzy drinks and fast food ≥1 time/week could possibly serve as an independent predictor for poor glycemic control, while fresh fruit could have a protective effect on glycemic control among T2D patients.
