New Study Finds Dietary Fiber May Lower Blood Pressure — What It Means for Your Heart


A new dietary fiber blood pressure study suggests that increasing fiber intake could help lower systolic and diastolic blood pressure for many adults. If confirmed, this could be a simple, heart-friendly habit you can adopt today. Fiber supports a healthy gut and weight management, while also stabilizing blood sugar—factors that influence blood pressure. Practical, fiber-rich options include oats, beans, lentils, apples, berries, leafy greens, nuts and seeds. Aim for about 25-38 grams of dietary fiber per day, depending on age and sex, and spread fiber intake across meals to avoid digestive discomfort. Behind the potential blood pressure benefits is the gut microbiome. The dietary fiber blood pressure study underscores the role of gut microbes in producing metabolites that help relax blood vessels and reduce inflammation. InnerBuddies offers a white-label Gut Health Operating System that can help you measure and act on these signals. Its Gut Microbiome Health Index ranges 0-100 and is powered by an exclusive collaboration with EAFIT University in Colombia. You can see how your microbial community compares via the top 40 bacteria, and you can interpret functional pathways as positive or negative with respect to a healthy cohort. InnerBuddies microbiome test makes this actionable for teams creating gut health testing products. Personalized nutrition advice in InnerBuddies uses data from three-day food diaries and stool samples to tailor fiber-focused strategies for your unique gut profile. The platform also includes target group analyses—think Healthy Aging, Endurance Sport, and other heart-relevant cohorts—so you can see how specific fiber types or foods influence your functional pathways. Plus, personalized probiotics and prebiotics recommendations can support your goals.
