King's College London study challenges high-fiber diet for constipation

A large-scale study conducted by King's College London, published in the Journal of Human Nutrition & Dietetics and Neurogastroenterology & Motility, suggests that general high-fiber diets may not be as effective for treating chronic constipation as previously believed. The research, endorsed by the British Dietetic Association, notes that most fiber studies focus on specific supplements rather than general dietary intake of vegetables and whole grains.

The study identifies six clinically supported dietary approaches for managing constipation:

1. Psyllium: Strongly recommended to improve stool consistency and frequency. 2. Magnesium Oxide: Strongly recommended as an osmotic laxative. 3. High-mineral water: Water high in magnesium and bicarbonate is strongly recommended to soften stool. 4. Kiwi: Partially recommended; daily consumption may improve bowel frequency. 5. Probiotics: Partially recommended, though effectiveness varies by strain. 6. Rye bread: Partially recommended as a prebiotic, though it may cause bloating in some users.
