Study: Grapes, blueberries boost gut health, reduce heart disease risk

New research published in *Food & Function* by lead author Dr. Jie Zheng from Zhejiang University found that daily consumption of foods rich in polyphenols like grapes and blueberries significantly improved gut microbiota and reduced markers of cardiovascular disease in a 12-week human trial. The study, involving 100 participants, observed noticeable changes in the gut microbiome composition and decreased inflammatory markers linked to heart health, suggesting a direct gut-heart axis benefit. It's not just about antioxidants anymore; it's about what they do to your gut bugs.
