The prevalence of high blood pressure is on the rise among younger individuals, and recent findings have linked exercise to changes in the diversity and configuration of gut microbiota. However, specific modifications to one's diet, such as incorporating blueberries while engaging in physical activity, can also influence this association. To explore the effects of exercise and blueberry consumption on gut bacteria, we conducted an eight-week study involving healthy and hypertensive college students. Our microbiome analysis revealed slight shifts in gut bacteria composition in response to increased physical activity, with significant changes in the diversity of the g_[Eubacterium]_eligens_group observed in hypertensive college students who regularly consumed blueberries. Although exercise and blueberry supplementation had a negligible impact on the gut microbiota diversity of healthy college students, it significantly boosted the production of butyric acid bacteria in hypertensive young adults. These results suggest that the changes in gut bacteria variety and abundance brought about by blueberries may be tied to alterations in the body composition of patients with hypertension. This study aims to reveal the impact of blueberry on the hypertensive students from a unique perspective, suggesting the impact of taking blueberry while taking exercises.
