Actionable Insights
1. Consume Fiber for Gut Health
Actively consume fiber to feed your gut bacteria, which prevents them from auto-digesting the protective mucin layer of your intestinal epithelial cells. This action helps guard against damage, leaky gut, and potential GI diseases like colitis and Crohn’s.
2. Obtain Both Soluble & Insoluble Fiber
Ensure your diet includes both soluble and insoluble fiber, as both types are required to form a functional gel in the intestine. This gel acts as a secondary barrier, preventing early absorption of calories and feeding your gut bacteria effectively.
3. Prioritize Real Food for Fiber
Choose real, whole foods as your primary source of fiber, rather than relying on fiber-fortified processed foods. Real foods naturally contain the necessary combination of both soluble and insoluble fiber, which is crucial for functional benefits, unlike many fortified products that often only add soluble fiber.
