SIBO, or Small Intestinal Bacterial Overgrowth, is a condition where too many bacteria grow in the small intestine. This can cause gas, bloating, pain, and other stomach issues. Many people with SIBO are told to follow a special diet. But what if you're vegan? Don’t worry—you can still manage your symptoms with a sibo diet vegan approach.
Let’s explore how to eat plant-based and still keep your gut happy.
What Is SIBO?
SIBO happens when bacteria that should stay in the large intestine move up into the small intestine. These bacteria ferment food too early, which causes discomfort.
Common symptoms include:
Bloating
Gas
Cramping
Diarrhea or constipation
Brain fog
Doctors often recommend diet changes as part of treatment. The low-FODMAP diet is one popular option. But vegans might struggle with this, since many high-FODMAP foods are plant-based.
Challenges of a Vegan SIBO Diet
Vegan diets are rich in fiber, legumes, fruits, and vegetables. However, many of these foods are high in FODMAPs. That makes a vegan SIBO diet tricky.
Some foods to limit or avoid:
Onions and garlic
Lentils and chickpeas
Apples and pears
Wheat and rye
Still, with planning, you can follow a [SIBO diet vegan] safely.
Vegan Low-FODMAP Foods
There are many plant-based foods that are low in FODMAPs and safe to eat with SIBO.
Here are some good choices:
Firm tofu
Zucchini
Spinach
Strawberries
Quinoa
Rice
Almond milk (unsweetened)
Pumpkin seeds
Always check portion sizes, as FODMAP content can vary.
Sample Vegan SIBO-Friendly Meals

Snack
A handful of walnuts or rice cakes

This sample plan avoids high-FODMAP foods while staying fully plant-based.
Tips for Success on a Vegan SIBO Diet

Supplements and Nutrients

Get enough calcium and iron from low-FODMAP sources
Consider digestive enzymes (if approved by your doctor)
