Association of 24-Hour Blood Pressure Variability With Cognition and Brain MRI Markers of Structural Change in Adults in Mid- to Late-Life

Background and objectives: Blood pressure (BP) fluctuates across the 24-hour period. High 24-hour BP variability (BPV) is associated with cardiovascular disease risk, yet its relevance for brain health is unclear. We aimed to examine associations …

Diet, Gut Microbiota, and Intestinal Permeability: Emerging Mechanisms in Hypertension Pathogenesis

Hypertension is a leading contributor to global morbidity and mortality, arising from the interplay of genetic and environmental risk factors together with the dysregulation of multiple physiological systems involved in blood pressure control. …

pH-sensor GPR68 plays a role in how dietary fibre lowers blood pressure in a preclinical model of hypertension

Dietary fibre lowers blood pressure (BP) via short-chain fatty acids, acidic metabolites released from fibre fermentation by bacteria in the large intestine. This acidic microenvironment may activate the pH-sensing receptor GPR68, primarily …

Preintervention Intake of Whole Grains Versus Refined Grains, and the Gut Microbiome, Discriminate the Antihypertensive Effect of Prebiotic Fiber

Full Citation Matthew Snelson, Dakota Rhys-Jones, Hamdi A Jama, Darren J Creek, Charles R Mackay, Jane Muir, Francine Z Marques, Preintervention Intake of Whole Grains Versus Refined Grains, and the Gut Microbiome, Discriminate the Antihypertensive Effect of Prebiotic Fiber, Circulation: Genomic and Precision Medicine 2025;18(5):e005019

Influence of angiotensin II on the gut microbiome: modest effects in comparison to experimental factors

Aims: Animal models are regularly used to test the role of the gut microbiome in hypertension. Small-scale pre-clinical studies have investigated changes to the gut microbiome in the angiotensin II hypertensive model. However, the gut microbiome is …

Breaking the Barrier: The Role of Gut Epithelial Permeability in the Pathogenesis of Hypertension

Purpose of the review: To review what intestinal permeability is and how it is measured, and to summarise the current evidence linking altered intestinal permeability with the development of hypertension. Recent findings: Increased gastrointestinal …

Recommendations for the Use of Dietary Fiber to Improve Blood Pressure Control

According to several international, regional, and national guidelines on hypertension, lifestyle interventions are the first-line treatment to lower blood pressure (BP). Although diet is one of the major lifestyle modifications described in …

Renal ACE2 (Angiotensin-Converting Enzyme 2) Expression Is Modulated by Dietary Fiber Intake, Gut Microbiota, and Their Metabolites

An important mechanism of action of SCFAs is via ligation with metabolite-sensing G-protein–coupled receptors. 5 Thus, we sought to determine whether these receptors were involved in Ace2 regulation. Given the significant redundancy between these …

Microbial Peer Pressure: The Role of the Gut Microbiota in Hypertension and Its Complications

There is increasing evidence of the influence of the gut microbiota on hypertension and its complications, such as chronic kidney disease, stroke, heart failure, and myocardial infarction. This is not surprising considering that the most common risk …
