Oats, plain rice and eggs are among the best foods for IBS because many people tolerate them and they can fit into a balanced, individualized eating plan. For hydration choices, see the best drinks for IBS.

What are 8 of the best foods for IBS?

The ai symptom analyzer can help you organize symptoms to discuss with a clinician; it cannot diagnose IBS or rule out other causes.

These foods are practical options, not a guaranteed ranking. IBS symptoms and triggers vary, and a food that works for one person may cause discomfort for another. Start with foods you enjoy, prepare them simply, and adjust the amount to your appetite and tolerance.

Several choices fit a low-FODMAP approach when portions and ingredients are appropriate. FODMAPs are carbohydrates that can draw water into the bowel or be fermented by gut bacteria, potentially contributing to diarrhea, gas and bloating in some people. They are not harmful to everyone, and many foods containing them have nutritional benefits.

Evidence is stronger for dietary patterns than for any single food on this list. A systematic review of randomized trials found that a low-FODMAP diet improved overall IBS symptoms compared with a habitual diet. That does not establish that each low-FODMAP food independently relieves symptoms.

Oats

Oats contain soluble fiber, which can hold water in the gut and may help with stool consistency. They can be a useful choice when constipation is a concern, although adding fiber too quickly can increase gas or bloating for some people.

Try a small bowl of plain cooked oats and adjust the amount gradually to what feels comfortable. Check flavored oatmeal for ingredients you may find troublesome, such as added sweeteners or dried fruit. Oats can be part of a low-FODMAP diet, but the amount and other ingredients matter.

Evidence: A review of diet and fiber for IBS discusses evidence for fiber in IBS. That is not proof that oats themselves will relieve an individual person's symptoms.

Plain rice

Plain rice contains little fermentable carbohydrate and is easy to serve without sauces or seasonings that may trigger symptoms. It can provide energy when you need a simple base for a meal. White rice has less fiber than brown rice, so relying mainly on white rice may not be ideal if constipation is your main concern.

Serve a portion of cooked rice alongside a protein and vegetables you tolerate. If you are unsure how a meal will sit, begin with a smaller portion and increase it as comfortable. Plain rice is different from a prepared rice dish containing onion, garlic or rich sauces.

Evidence: Rice is a practical choice within some low-FODMAP eating patterns. The available dietary trials do not show that rice alone treats IBS.

Eggs

Eggs contain protein and do not contain FODMAP carbohydrates. For someone who tolerates them, they offer an option for a meal without relying on foods that may be harder to manage during a low-FODMAP trial.

Try a serving of fully cooked eggs with rice, potatoes or another food you tolerate. Boiled, poached or simply scrambled eggs let you judge the eggs separately from rich sauces and large amounts of added fat. Fried or heavily seasoned preparations may be less comfortable for some people.

Evidence: Eggs fit the logic of a low-FODMAP diet, but research has not established that eating eggs reduces symptoms. Avoid them if you have an egg allergy, and choose another protein if they consistently cause discomfort.

Firm tofu

Plain firm tofu supplies protein and can be useful if you want a plant-based alternative to foods that cause symptoms. Firm tofu is generally more suitable for a low-FODMAP approach than some softer varieties, but products and portions differ.

Start with a modest serving of plain firm tofu as part of a meal and adjust to your tolerance. Check marinades and ready-made sauces for onion, garlic or other ingredients you already know are problematic. If soy itself causes symptoms for you, another protein may be a better choice.

Evidence: Tofu may help make a low-FODMAP diet more varied; it is not a proven IBS treatment. Research on the overall diet should not be interpreted as a trial showing that firm tofu independently improves symptoms.

Carrots

Carrots provide a vegetable option that can fit into a low-FODMAP meal. Including tolerated vegetables helps maintain variety rather than removing plant foods altogether. Carrots are not a remedy for IBS, and how comfortable they feel can vary by person and preparation.

Try a small serving of plain cooked carrots alongside rice and a protein, then adjust the portion as needed. Some people prefer the texture of cooked vegetables, while others tolerate raw carrots well. Cooking does not guarantee that a food will be symptom-free.

Evidence: The evidence supports dietary strategies for some people with IBS, not carrots as an individual treatment. Judge them by your own response rather than assuming you need to eat them for symptom control.

Potatoes

Plain potatoes provide carbohydrate and can be prepared without common high-FODMAP seasonings. They offer another meal base if you want variety instead of eating rice every day. The ingredients added to potatoes can matter as much as the potato itself.

Try a portion of boiled, baked or mashed potato, prepared simply. If lactose or rich foods bother you, consider what you add when making mashed potatoes; onion, garlic and fatty toppings may also be triggers for some people. Adjust the serving to your appetite and tolerance.

Evidence: Potatoes are a food choice compatible with a low-FODMAP pattern when prepared appropriately. There is no evidence in the studies we found that potatoes themselves treat IBS.

Lactose-free yogurt

Lactose-free yogurt can provide protein and calcium without the lactose that causes symptoms in some people. Lactose intolerance and IBS can overlap, but not everyone with IBS needs to avoid lactose.

If you want to try yogurt, start with a small serving of plain lactose-free yogurt and check the label for sweeteners or fruit additions that you know bother you. Adjust the amount to your tolerance. Avoid dairy yogurt if you have a milk allergy; lactose-free products still contain milk proteins.

Evidence: Reducing a poorly tolerated carbohydrate may help an individual, but lactose-free yogurt itself is not established as an IBS treatment. Yogurts also differ, so a probiotic claim on a label does not guarantee symptom relief.

Oranges

An orange can provide fruit, fluid and nutrients while adding variety to meals and snacks. Some fruit can be difficult for people sensitive to particular FODMAPs, but avoiding all fruit is usually unnecessary.

Try a modest serving of whole orange and see how you feel. You can pair it with another tolerated food rather than changing several foods at once. If citrus consistently causes discomfort, choose a different fruit you tolerate; an orange is an option, not a requirement.

Evidence: Oranges can fit into an individualized low-FODMAP eating plan, but the studies we found do not show that oranges independently relieve symptoms. Tolerance and the amount eaten still matter.

Which foods should you limit with IBS?

Limit foods based on a consistent pattern of symptoms, not a blanket rule. Common possibilities include onion and garlic, some beans and lentils, lactose-containing dairy, certain fruits, and products sweetened with polyols such as sorbitol or mannitol. Fatty meals can also be uncomfortable for some people, although fat is not a FODMAP.

Wheat-containing foods may be troublesome for some people because of their fructans, a type of FODMAP. That does not mean everyone with IBS needs a gluten-free diet. If celiac disease is a possibility, speak with a clinician before cutting out gluten, because removing it can affect testing.

If straightforward changes do not help, ask a clinician or dietitian whether a structured low-FODMAP trial is appropriate. It involves a temporary restriction phase followed by reintroduction and personalization, not indefinite avoidance of every high-FODMAP food. A controlled trial of a low-FODMAP diet found lower overall symptom scores than with a typical diet, but restrictive diets can be burdensome and are not suitable for everyone.

Who should be careful, and when should you see a doctor?

See a clinician if symptoms are new, persistent or changing rather than assuming they are IBS. Seek prompt medical assessment for unexplained weight loss, persistent diarrhea that wakes you at night, or known anemia. Get urgent medical help for severe or sudden abdominal pain, black or bloody stools, fainting, or persistent vomiting with an inability to keep fluids down.

Get professional advice before restricting foods if you are pregnant, feeding a child, have a history of an eating disorder, or have another condition such as diabetes, celiac disease or inflammatory bowel disease. A clinician or registered dietitian can help keep the diet nutritionally adequate and assess possible medication or condition-related concerns. A review of dietary management in IBS notes the nutritional and eating-disorder risks that restrictive diets can present.
