Small Intestinal Bacterial Overgrowth, or SIBO, is a digestive disorder that can cause a range of uncomfortable symptoms, such as bloating, gas, and abdominal pain. The SIBO diet is a therapeutic approach that aims to reduce symptoms by limiting the types of carbohydrates that feed bacteria in the small intestine. This diet can be challenging to follow, but it has shown promise in managing SIBO symptoms. In this article, we’ll explore the benefits of the SIBO diet, and how it works, and provide a food list and sample menu to help guide you on your SIBO journey.
What is
The SIBO diet is a dietary approach used to manage symptoms of small intestinal bacterial overgrowth (SIBO), a condition in which there is an overgrowth of bacteria in the small intestine. The goal of the SIBO diet is to limit the intake of carbohydrates that feed the bacteria in the small intestine, thereby reducing symptoms such as bloating, gas, diarrhea, and abdominal pain. The SIBO diet is typically followed in conjunction with other SIBO treatments, such as antibiotics or herbal therapies, and should be supervised by a healthcare provider. The SIBO diet may also be referred to as the Low FODMAP diet.
Potential Benefits
The potential benefits of the SIBO diet include:
- Reduced symptoms
The SIBO diet can help reduce symptoms associated with SIBO, such as bloating, gas, abdominal pain, diarrhea, and constipation. - Improved digestion
By limiting the intake of carbohydrates that feed bacteria in the small intestine, the SIBO diet may help improve digestion and nutrient absorption. - Better gut health
The SIBO diet may help improve the overall health of the gut by reducing inflammation and promoting a healthy balance of gut bacteria. - Improved quality of life
By reducing symptoms and improving gut health, the SIBO diet may help improve the quality of life for individuals with SIBO. - May reduce antibiotic use
By using dietary changes to manage SIBO symptoms, individuals may be able to reduce their reliance on antibiotics, which can have side effects and contribute to antibiotic resistance.
Potential Downsides
Some potential downsides of the SIBO diet include:
- Nutrient deficiencies
This diet restricts certain types of carbohydrates, which can limit the intake of important nutrients such as fiber, vitamins, and minerals. It’s important to work with a healthcare provider to ensure that nutrient needs are being met. - Limited food choices
The SIBO diet can be restrictive, which may make it difficult to follow long-term. Some individuals may find the diet to be too limiting or challenging to stick to. - Social limitations
This diet may make it difficult to eat out or socialize around food, which can be isolating and impact social relationships. - Potential for weight loss
While weight loss may be a desired outcome for some individuals, the SIBO diet may result in unintentional weight loss for others. - May not work for everyone
The SIBO diet is not a one-size-fits-all approach and may not work for everyone. It’s important to work with a healthcare provider to determine the best treatment approach for individual needs.
How it Works
The SIBO diet works by limiting the intake of certain types of carbohydrates that feed bacteria in the small intestine. When there is an overgrowth of bacteria in the small intestine, these bacteria can ferment carbohydrates and produce gas, leading to symptoms such as bloating, gas, and abdominal pain. By limiting the intake of these carbohydrates, the SIBO diet aims to reduce the amount of gas produced by the bacteria and alleviate symptoms.
This diet typically involves limiting or avoiding certain carbohydrates, such as lactose, fructose, and other fermentable carbohydrates known as FODMAPs. This can involve eliminating certain foods or reducing the portion sizes of certain foods. The diet may also include foods that are less likely to be fermented by bacteria, such as proteins, fats, and non-starchy vegetables.
It’s important to note that the SIBO diet should be followed in conjunction with other SIBO treatments, such as antibiotics or herbal therapies, and should be supervised by a healthcare provider. This diet may also be used as a short-term approach to alleviating symptoms while the underlying causes of SIBO are being addressed.
How to Follow
Following the SIBO diet involves limiting the intake of certain types of carbohydrates that can feed bacteria in the small intestine. Here are some general guidelines for following the SIBO diet:
- Eliminate or limit high FODMAP foods
This includes foods such as wheat, rye, barley, onions, garlic, legumes, and certain fruits such as apples, pears, and stone fruits. It’s important to note that not all high FODMAP foods need to be eliminated, but rather should be consumed in moderation or small amounts. - Limit lactose
Avoid or limit dairy products that contain lactose, such as milk, cheese, and yogurt. Lactose-free alternatives may be substituted. - Choose low-FODMAP fruits and vegetables
These include berries, citrus fruits, bananas, carrots, cucumbers, lettuce, and spinach. - Avoid sweeteners that can feed bacteria
This includes artificial sweeteners, honey, and agave nectar. - Choose lean proteins
Opt for lean protein sources such as chicken, fish, turkey, and tofu. - Avoid processed foods
Processed foods are often high in FODMAPs and may contain additives that can irritate the gut. - Work with a healthcare provider
It’s important to work with a healthcare provider who can provide guidance on the SIBO diet, monitor symptoms, and ensure that nutrient needs are being met.
It’s important to note that the SIBO diet should be followed in conjunction with other SIBO treatments, such as antibiotics or herbal therapies, and should be supervised by a healthcare provider. The diet may also be used as a short-term approach to alleviating symptoms while underlying causes of SIBO are being addressed.
Food to Eat
Here are some foods that are typically allowed on the SIBO diet:
- Non-starchy vegetables
such as spinach, kale, lettuce, zucchini, cucumbers, and broccoli. - Low FODMAP fruits
such as bananas, blueberries, strawberries, kiwi, and oranges. - Lean proteins
such as chicken, turkey, fish, eggs, and tofu. - Gluten-free grains
such as rice, quinoa, and buckwheat. - Nuts and seeds
such as almonds, walnuts, sunflower seeds, and pumpkin seeds. - Healthy fats

It’s important to note that the SIBO diet is individualized, and some people may need to avoid certain foods that are typically allowed on the diet. It’s best to work with a healthcare provider or a registered dietitian who specializes in SIBO to determine which foods are appropriate for your specific needs.
Food to Avoid
Here are some foods to avoid on the SIBO diet:
- High FODMAP fruits and vegetables

especially beer and wine, which contain high amounts of fermentable carbohydrates.
It’s important to note that the SIBO diet is individualized, and some people may need to avoid additional foods based on their specific needs. Working with a healthcare provider or a registered dietitian who specializes in SIBO can help determine which foods are appropriate to avoid for your specific case.
