3. Soybean Hulls

Soybean hulls are another excellent source of dietary fiber, known for enhancing gut health by increasing the density of villi in the intestines and reducing harmful bacteria like E. coli3.

4. Citrus Pulp

Citrus pulp is rich in soluble fiber, which improves nutrient digestibility and gut health. It also increases the viscosity of stomach contents, which can aid in digestion3.

5. Oat Bran

Barley bran, like oat bran, is beneficial for cholesterol management. Although it does not significantly lower blood cholesterol, it contributes to overall dietary fiber intake5.

8. Chickpea and Soybean Husks

These husks are used as baking additives to enhance the nutritional profile of bread. They improve the bread’s texture and antioxidant properties, making them a functional fiber source9.

9. Sugar Beet Fiber

Sugar beet fiber is included in high-fiber diets to reduce inflammation markers like C-reactive protein, which can help lower the risk of cardiovascular diseases8.

10. Psyllium Seed Husks
