Dietary fibre and the gut microbiome: implications for glucose homeostasis.

ABSTRACT:

Purpose of review

Despite long-standing evidence linking dietary fibre intake to improved glycaemic control and reduced chronic disease risk, most individuals fail to meet recommended intake levels. As interest grows in the gut microbiota's role in mediating fibre's health effects, this review evaluates recent human intervention trials to assess whether dietary fibre improves glucose homeostasis through microbiota-dependent mechanisms.

Recent findings

Nine recent randomised controlled trials (RCTs) have examined the effects of dietary fibre on glycaemic markers and gut microbiota, primarily in individuals at risk of or diagnosed with metabolic disease. Five studies reported improvements in glycaemic outcomes such as fasting glucose, insulin, or HOMA-IR. Microbial responses w
