What Are Whole Grains Fiber?
Whole grains aren’t just fiber, they are complete packages of nutrition containing;
- Bran (fiber-rich outer layer)
- Endosperm (starchy middle)
- Germ (nutrient- packed core)
These products contain higher dietary fiber than refined grains, with a balanced profile of soluble and insoluble fiber. This composition makes them particularly effective for reducing non-communicable disease (NCD) risks.
