Ever wondered if fruit fiber (eg, citrus pulp, apple fiber, etc.) is better than fiber from grains (eg, oats, wheat)? A recent published article studied bran vs. fruit fibers and discovered many health-relevant results.

Authors found that bran fibers: 1) improved gut microbiota diversity, 2) increased beneficial gut microbiota, 3) reduced blood triglycerides while fruit fibers: 1) changed microbiota composition and function, 2) tended to improve immune response, and 3) lowered cholesterol levels. 

In summary, both types of fibers improved gut and systemic health in dogs. However, the types of benefits varied based on fibers. It makes one wonder if a broader set of benefits would be derived by blending the types of fibers.
