Small Intestinal Bacterial Overgrowth (SIBO) is a condition where excessive bacteria in the small intestine cause symptoms like bloating, gas, and abdominal pain. Diet plays a crucial role in managing SIBO by reducing bacterial fermentation and alleviating discomfort. A well-structured SIBO diet focuses on low-FODMAP foods, minimizing sugars, and avoiding fermentable carbohydrates to promote gut balance and support overall treatment.
1.1 What is SIBO (Small Intestinal Bacterial Overgrowth)?
Small Intestinal Bacterial Overgrowth (SIBO) occurs when excessive bacteria populate the small intestine, disrupting normal digestion. This overgrowth can lead to symptoms like bloating, gas, and abdominal pain. Factors such as slow bowel motility or low stomach acid contribute to SIBO development, creating an environment where bacteria thrive, impacting nutrient absorption and overall gut health.
1.2 Symptoms of SIBO and the Role of Diet in Management
Common SIBO symptoms include bloating, gas, abdominal pain, nausea, and indigestion. Diet plays a pivotal role in managing these symptoms by reducing bacterial fermentation. Avoiding high-FODMAP and fermentable foods helps minimize discomfort, while low-FODMAP options alleviate digestive issues. A structured dietary approach is essential for controlling symptoms and supporting overall gut health in SIBO patients.

Overview of the SIBO Diet
The SIBO diet focuses on low-FODMAP foods, moderate fiber, and low fat to reduce symptoms. It restricts sugars and carbs that feed bacteria, aiding symptom relief and treatment support.
2.1 Key Principles of the SIBO Diet
The SIBO diet focuses on reducing bacterial fermentation by limiting high-FODMAP foods, sugars, and fermentable carbohydrates. It emphasizes low-FODMAP options, moderate fiber, and low fat to minimize symptoms like bloating and abdominal pain. The diet also avoids raw vegetables and certain starches, creating an environment less favorable for bacterial overgrowth while supporting overall gut health and treatment efficacy.
2.2 The 3-Phase SIBO Diet Approach
The CanXida Protocol offers a structured 3-phase diet plan for SIBO management. Phase 1 focuses on elimination to reduce symptoms, Phase 2 reintroduces foods cautiously, and Phase 3 emphasizes long-term maintenance. This approach helps minimize bacterial fermentation, alleviate discomfort, and restore gut balance, providing a clear roadmap for managing SIBO effectively through dietary adjustments.

SIBO Food List: What to Eat and Avoid
A SIBO food list categorizes foods into “Eat,” “Limit,” and “Avoid.” Focus on low-FODMAP, non-fermentable carbs, and avoid high-FODMAP foods to reduce bacterial fermentation and symptoms.
3.1 Foods to Eat: Low-FODMAP and SIBO-Friendly Options
Focus on low-FODMAP foods like bananas, berries, bell peppers, and leafy greens. Include SIBO-friendly proteins such as chicken, turkey, and fish. Opt for gluten-free grains like rice and quinoa. Healthy fats like olive oil and avocado are also beneficial. Portion control is key, as even tolerated foods can cause issues in excess. Gradually introduce new foods to monitor tolerance and manage symptoms effectively.
3.2 Foods to Avoid: High-FODMAP and Fermentable Carbohydrates
Avoid high-FODMAP foods like onions, garlic, beans, lentils, and certain fruits such as watermelon and mangoes. Fermentable carbohydrates, including processed sugars and sugar substitutes, can exacerbate symptoms. Limit or eliminate dairy products, especially those high in lactose, and avoid alcohol. These foods feed bacteria, worsening bloating and discomfort. Refer to a SIBO food chart for a detailed list of items to exclude.

Understanding FODMAPs and Their Impact on SIBO
FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) are carbohydrates that can ferment in the gut, worsening SIBO symptoms like bloating and gas. Managing FODMAP intake is key to reducing discomfort and promoting gut balance for those with SIBO.
4.1 What Are FODMAPs and How They Affect the Gut
FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) are types of carbohydrates that can be poorly absorbed in the gut. When undigested, they ferment in the intestine, producing gas and causing bloating, pain, and discomfort, particularly in individuals with SIBO. Managing FODMAP intake is essential to reduce symptoms and support gut health.
4.2 Low-FODMAP Food Choices for SIBO Management
Low-FODMAP foods are essential for managing SIBO symptoms by minimizing gut fermentation. Focus on selecting fruits like bananas and berries, vegetables such as cucumbers and carrots, lean proteins, and gluten-free grains. Avoid high-FODMAP options like onions, garlic, and legumes. Incorporating these foods helps reduce bloating and discomfort, promoting a balanced and symptom-free digestive system tailored to individual tolerance.

5.1 Phase 1: Elimination and Symptom Relief
Phase 1 focuses on eliminating high-FODMAP foods, sugars, and processed carbohydrates to reduce bacterial fermentation and alleviate symptoms like bloating and abdominal pain. By adhering to a strict low-FODMAP diet, individuals can quickly achieve symptom relief and create a foundation for gut healing. This phase is critical for stabilizing the digestive system before reintroducing foods.
5.2 Phase 2: Reintroduction of Foods
Phase 2 involves gradually reintroducing foods to identify tolerance and expand dietary options. Start with small portions of low-FODMAP foods, tracking symptoms. This phase helps determine individual food triggers and promotes a more balanced diet. It’s crucial to reintroduce one food at a time and monitor reactions to avoid relapse. A symptom journal is highly recommended for accurate tracking.
5.3 Phase 3: Maintenance and Long-Term Management
Phase 3 focuses on long-term management by tailoring the diet to individual needs. Emphasize SIBO-friendly foods while minimizing high-FODMAP options. Regular monitoring of symptoms ensures sustained relief. Some may need to continue the diet indefinitely, while others gradually expand their food choices. Periodic reassessment and adjustments are key to maintaining gut health and preventing recurrence.

Managing SIBO Symptoms Through Dietary Changes
Dietary changes are key to managing SIBO symptoms. Focus on low-FODMAP foods, minimize sugars, and avoid fermentable carbs to reduce bloating and improve digestion and comfort.
