Overview

• The guidelines, jointly published in the Journal of Human Nutrition & Dietetics and Neurogastroenterology & Motility, synthesize more than 75 trials into 59 recommendations and 12 research priorities.
• Recommended options supported by evidence include kiwifruit, rye bread, high mineral-content water, psyllium fiber, certain probiotic strains, magnesium oxide, and prunes.
• The panel found limited evidence for generic high-fiber diets and senna supplements, challenging long-standing advice given to many patients.
• The guidance emphasizes personalized targets such as stool frequency, consistency, straining, and quality of life, and is accompanied by a clinician-friendly implementation tool.
• Authors note that overall evidence quality is low to moderate and call for rigorous, whole-diet trials, with examples like 2–3 kiwifruits daily for at least four weeks showing benefit in small studies.
