Overview
- The statements, co‑published October 13 in the Journal of Human Nutrition and Dietetics and Neurogastroenterology & Motility, distill four systematic reviews covering more than 75 randomized trials into 59 recommendations.
- For symptom relief, the authors advise eating two to three kiwifruits daily for at least four weeks, with either green or gold varieties suitable and the peel providing additional fiber.
- Additional options include 0.5–1.5 liters per day of mineral water for two to six weeks, magnesium oxide at 0.5–1.5 grams per day, six to eight slices of rye bread daily, and psyllium at 10 grams or more per day.
- The guidance does not support a blanket high‑fibre diet for constipation based on available randomized evidence, though fiber supplementation shows benefit.
- The recommendations apply to otherwise healthy adults, with cautions for children, pregnancy or secondary causes, gluten intolerance with rye bread, and kidney disease or medication interactions with magnesium.
