Dose- and Time-Dependent Effect of Dietary Blueberries on Diabetic Vasculature Is Correlated with Gut Microbial Signature.

Evidence from our lab and others indicates the vascular effects of dietary blueberries. In the present study, we determined dietary blueberries' dose- and time-dependent effects on diabetic vasculature and their association with gut microbes. Seven-week-old / diabetic male mice were fed a diet supplemented with ± freeze-dried wild blueberry powder (FD-BB) for 4, 8, or 12 weeks (three cohorts).
