Clinical Considerations
The role of dietary management in canine diabetes mellitus and colitis is to provide a proper balance of total nutrients while meeting the special dietary needs of the patient. Complex carbohydrates and dietary fiber help to delay the absorption of glucose from the intestinal tract and minimize postprandial fluctuation of glucose in dogs with diabetes mellitus. Soluble fiber in the diet may also prolong gastrointestinal transit time, allow greater water absorption, and promote the production of short chain fatty acids which nourish the intestinal mucosa.
