Background: Beneficial effects of flavonoids on cardiovascular complications have been subject of considerable interest. This study, therefore, was carried out to investigate effects of freeze-dried strawberry (FDS) beverage in comparison with strawberry flavored drink on lipid profile, glycemic control and blood pressure after six weeks supplementation in type II diabetic (T2D) patients. Methods: In a randomized double blind control trial, thirty six subjects with T2D (23 females; mean age: 51.57 ? 10 years [means ? SE]) were randomly divided into two groups to consume either 2 cups of freeze-dried strawberry beverage (50g equivalent to 2 servings fresh strawberries) or iso-caloric drink with strawberry flavor daily for 6 weeks. Anthropometric measurements, blood pressure, fasting blood glucose and lipid profile were measured at baseline and 6 weeks post intervention. Results: There was a significant reduction in total cholesterol levels and total cholesterol to HDL-C ratio in intervention group (-%13.8; p<0.05 and -%7.1; p<0.01, respectively). Systolic and diastolic blood pressure were also significantly reduced post intervention with FDS drink (-%15.9 and -%4.6; p<0.05, respectively). Serum glucose, triglycerides, HDL-C concentrations and anthropometric indices showed no significant differences between the groups. Conclusions: Short-term FDS supplementation improved selected cardiovascular risk factors in subjects with T2D. Long-term effects of FDS supplementation on other metabolic biomarkers need to be investigated in future trials.
