- The useful idea
Dietary fiber, fibre, or roughage is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes.
- How it works
Dietary fibers are diverse in chemical composition and can be grouped generally by their solubility, viscosity and fermentability which affect how fibers are processed in the body.
- Why it matters
Dietary fiber has two main subtypes: soluble fiber and insoluble fiber which are components of plant-based foods such as legumes, whole grains, cereals, vegetables, fruits, nuts, and seeds.
Why this matters
