Parental diet and offspring health: a role for the gut microbiome via epigenetics

The effects of diet and nutrition extend beyond individual health: food intake before conception or during pregnancy and lactation can affect the health of offspring. Diet is one of the most powerful modulators of the gut microbiome, influencing …

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

Effects of Nut Intake on Gut Microbiome Composition and Gut Function in Adults: A Systematic Review and Meta-analysis

The reduced risk of chronic diseases such as cardiovascular disease and type 2 diabetes associated with nut consumption may occur via modulation of the gut microbiota, although this has not been comprehensively assessed. This systematic review of …

Gut-Heart Axis: The Role of Gut Microbiota and Metabolites in Heart Failure

Heart failure is a global health issue with significant mortality and morbidity. There is increasing evidence that alterations in the gastrointestinal microbiome, gut epithelial permeability, and gastrointestinal disorders contribute to heart …

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 …

From hype to hope: Considerations in conducting robust microbiome science

Microbiome science has been one of the most exciting and rapidly evolving research fields in the past two decades. Breakthroughs in technologies including DNA sequencing have meant that the trillions of microbes (particularly bacteria) inhabiting …
