SIBO (small intestinal bacterial overgrowth) is a gastrointestinal disorder that occurs when there is an excess of bacteria in the small intestine. This can cause a variety of symptoms, such as bloating, gas, diarrhea, constipation, abdominal pain, and fatigue.
The low-FODMAP diet is key in treating SIBO, as it helps reduce symptoms by limiting foods that can ferment in the intestine and cause discomfort.
What can you eat with SIBO?
The SIBO diet is a low-FODMAP diet, which stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are types of carbohydrates that are difficult to digest and can cause symptoms in people with SIBO.
Some examples of low-FODMAP foods include:
- Proteins: Meat, chicken, fish, eggs, tofu, tempeh
- Vegetables: Most leafy greens, cucumbers, zucchini, carrots, tomatoes
- Fruits: Blueberries, raspberries, strawberries, kiwis, ripe bananas
- Grains: Rice, quinoa, amaranth
- Dairy products: Lactose-free milk, lactose-free yogurt, lactose-free cheese
- Fats: Olive oil, coconut oil, avocado

What should you avoid with SIBO?
Some examples of high-FODMAP foods to avoid include:
- Fructans: Onion, garlic, leek, wheat, rye, barley
- Fructose: Apples, pears, watermelon, mango, honey, high-fructose corn syrup
- Galactans: Beans, lentils, chickpeas
- Lactose: Milk, cheese, yogurt
- Polyols: Artificial sweeteners, sorbitol, mannitol, xylitol
Additional tips for the SIBO diet:
- Eat small, frequent meals throughout the day.
- Chew food thoroughly.
- Drink plenty of fluids.
- Avoid alcohol and carbonated beverages.
- Keep a food diary to track what you eat and how you feel.
- Talk to your doctor about probiotic supplements.
It’s important to remember that this diet is temporary and restrictive, and its goal is to restore balance to the gut microbiome.
It is recommended to follow the diet for a period that can vary between two and eight weeks, depending on the severity of symptoms and under the supervision of a healthcare professional.
It’s important to note that this is only a general guide. The best way to know which foods are right for you is to work with a registered dietitian or nutritionist who has experience with SIBO to get a personalized treatment plan tailored to your specific needs.
