stock here: I have have decades been a fan of pro-biotics, but there is more to gut types, and I have no idea how this guy has so much money to advertise on YouTube, LOL.
Dr. Gundry describes three main gut types that influence how we process food, manage weight, and maintain overall health. Recognizing your type can help tailor diet and supplement strategies. Here’s an overview based on his framework:
————————————————
- Lectin-Sensitive Gut
Who: People whose microbiome and gut lining react poorly to lectins—the plant proteins found in raw beans, grains, nightshades, etc.
Symptoms: Bloating, gas, autoimmune flares, brain fog.
Approach:
Avoid high-lectin foods, especially those not properly prepared (raw beans, kidney beans, tomatoes, etc.).
Use soaking, pressure cooking, peeling, fermenting to reduce lectin content
Monitor for symptom improvement after lectin elimination.
———————————————
- Fermenter / Fiber-Responder Gut
Who: Individuals whose gut thrives on prebiotic fibers (e.g., inulins, resistant starches).
Symptoms & Benefits: Regular bowel movements, good energy, healthy microbiome diversity.
Approach:
Emphasize prebiotic-rich foods like chicory, onions, green bananas, cooled white rice, mushrooms
Combine with fermented foods (yogurt, kefir, kimchi) as Gundry found that prebiotics + postbiotics = greater microbiome diversity and lower inflammation
Maintain regular intake of resistant starches and fermented foods.
————————————
- Leaky Gut / “Barrier” Gut
Who: Individuals with compromised gut barrier that allows antigens to pass into the bloodstream, triggering immune responses.
Symptoms: Chronic inflammation, fatigue, autoimmune issues, food sensitivities .
Approach:
Adopt a lectin-free or reduced-lectin diet to protect tight junctions
Supplement with glutamine, polyphenols, collagen, and high-quality olive oil to support gut lining.
Incorporate probiotics and prebiotic fiber to help repair the barrier and restore immune balance.
🔄 Overlapping Gut Types
It’s common to belong to more than one category:
Many lectin-sensitive individuals also have leaky gut, especially if they suffer autoimmune or chronic inflammation.
Fermenters may not thrive unless their gut barrier is sound—so supporting type 2 with type 3 strategies can create synergy.

Symptom tracking: Note if removing lectins improves digestion, whether eating resistant starch increases regularity, or if barrier-supporting supplements ease inflammation.
✅ Practical Roadmap
Gut Type Core Strategy
Lectin-Sensitive Remove/reactively prepare lectin-rich foods
Fermenter Add prebiotics + fermented foods consistently
Leaky Gut Use gut barrier-supportive diet & supplements
⚠️ Clinical Perspective
While Gundry’s system is popular among patients, it’s worth noting scientific controversy—critics say evidence is limited, and many lectin-rich foods remain healthful in standard Western diets
