12 Common SIBO Trigger Foods

If you’ve got small intestinal bacterial overgrowth (SIBO), some of the healthiest foods can cause the most bloating, gas, and discomfort.

Here are the repeat offenders I see most:

🧅 Onion
🧄 Garlic
🍎 Apples
🥣 Beans (all of them)
🥦 Broccoli (florets not as bad)
🥙 Hummus/chickpea
🍇 Dried fruits (all of them)
🌸 Cauliflower
🧃 Fruit juices (all of them)
🥗 Raw vegetables (all of them)
🥬 Brussel sprouts
🥛 Milk (*NOTE: lactose free cows milk is often fine. Plant based milks without any additives besides water and salt are often fine)

These are all high in fermentable sugars (FODMAPs) or tough-to-digest fibers, which can cause a lot of symptoms if you have SIBO.

💡 Important: You don’t need to avoid these forever. The goal is to treat the root cause, rebalance the gut, and then reintroduce the healthy foods you enjoy with less reactivity.
