Dietary fiber refers to plant-derived carbohydrates that are not fully digested by the human gastrointestinal system. It includes both soluble and insoluble fibers, which have different physiological effects. In the context of physical activity, fiber supports gut health, aids in digestion, and can regulate energy release.
Soluble fiber dissolves in water and helps manage cholesterol and blood sugar levels, while insoluble fiber adds bulk to stools and promotes regular bowel movements.
Active individuals benefit from adequate fiber intake for gastrointestinal health and overall metabolic balance. Fiber is often included in meal replacement shakes, health-focused supplements, and gut health products.
