Soluble vs Insoluble Fiber: How Each Type Helps Constipation and Gut Health
Fibre isn’t a single nutrient: soluble fibre dissolves in water to form a gel that softens stool, acts as a prebiotic, and may help lower cholesterol, while insoluble fibre adds bulk to stool and helps move it through the gut; most foods contain a mix of both, so constipation relief comes from including a balance of soluble and insoluble fibre from varied sources (e.g., psyllium, oats, wheat bran, fruits and vegetables).
