The IBS diet is a short-term elimination diet that helps manage IBS symptoms. It is not a singular diet plan. It instead consists of various diet strategies to reduce symptoms and gradually reintroduce eliminated foods to identify the specific triggers that provoke those symptoms. Based on the observations made during this diet, a dietitian may customize the diet plans to suit an individual’s specific IBS conditions and requirements for long-term management.

Irritable bowel syndrome is a functional intestinal disorder characterized by recurrent abdominal pain, flatulence, bloating, diarrhea, and constipation. However, fixing one’s diet and gut microbiome may help manage the symptoms.

According to the International Foundation for Gastrointestinal Disorders, 5% to 10% of the global population has IBS. Approximately, 20% to 40% of annual gastroenterologisti  A medical expert specializing in the diagnosis, treatment, and prevention of gastrointestinal diseases. visits are due to IBS. Further, there are 2.4 to 3.5 million annual physician visits for IBS in the US alone (1).

Currently, 25 to 45 million people in the US are affected by this condition. Men account for 35% to 40% of the cases while women account for 60% to 65% of the cases. This disorder also impacts 6% to 14% of the global adolescent population and shows consistent symptoms (1).

IBS symptoms require immediate medical intervention, and one of the first measures taken is dietary modification.

IBS can have a severe impact on your day-to-day life. A 2018 online survey conducted on people with self-reported IBS found that 68.8% reported at least one bowel syndrome in the last 12 months. Further, the prevalence of IBS symptoms such as bloating, diarrhea, and flatulence were higher in women than in men.

The next section will help you understand what foods you can include in your IBS diet.

Foods To Eat On The IBS Diet

While the food items may vary based on the IBS diet type, the following list includes foods that you may consume with IBS:

  • Fruits: Bananas, raspberries, blueberries, strawberries, kiwis, grapes, and oranges
  • Vegetables: Cucumbers, lettuce, carrots, zucchini, pumpkin, eggplant, and bell peppers
  • Proteins: Chicken, eggs, turkey, fish, tofu, red meat (in moderation, only if you can tolerate it)
  • Gluten-Free Grains: Rice (white or brown), quinoa, and gluten-free certified oats
  • Nuts And Seeds (In Moderation): Almonds, walnuts, pine nuts, macadamia nuts, and pecans
  • Herbs And Spices: Ginger, basil, thyme, oregano, black pepper, cilantro, sage, and paprika

  • Sweeteners: Stevia, glucose, dextrose, and agave
  • Beverages: Herbal teas, juices from the fruits mentioned above (low-quantity), and lactose-free drinks

Now that you know what foods you can eat on this diet, it is equally important to learn about the foods you should avoid to further aggravate the symptoms.

Foods To Avoid On The IBS Diet

The following foods may trigger IBS symptoms and are thus eliminated from the IBS diet:

  • Fruits: Apples, pears, peaches, mangoes, cherries, watermelon, plums, and nectarines
  • Vegetables: Cauliflower, mushroom, broccoli, Brussels sprouts, onions, garlic, artichoke, and asparagus (to be avoided in raw forms as well as they are difficult to digest)
  • Processed Foods: All processed foods, including sausages, deli meats, hot dogs, etc., as they contain preservatives and additives
  • Wheat Products: Pasta, cereals, and bread
  • Legumes: Chickpeas, black beans, lentils, and kidney beans
  • Dairy Products: Lactose-containing milk, yogurt, soft cheese, and cream
  • High-Fat Foods: Deep-fried, greasy foods and fatty meat cuts (may worsen bloating) (2)
  • Spicy Foods: Too much spice can irritate the digestive tract and trigger IBS symptoms(2)
  • Drinks: Coffee, caffeinated drinks, sodas, carbonated drinks, and alcoholic beverages
  • Sweeteners: High-fructose ingredients, sorbitol, xylitol, and mannitol
  • High-Sugar Foods: Sugary desserts, snacks, and candies (may trigger IBS symptoms) (3)

It is important to note that overeating may also disturb digestive functions and exacerbate IBS symptoms. Eat smaller and frequent meals spread throughout the day for easier digestion.

The actual diet recommended to an individual with IBS also depends on the severity of the symptoms and their food sensitivities. We shall now explore a few popularly adopted IBS diets that may also be tailored to an individual’s needs.

Common Types Of IBS-Friendly Diets

Your personalized IBS diet includes two widely accepted diet plans and suggestions from your healthcare expert.  Let us take a look at what they are and how they may help with IBS.


The low-FODMAP diet

The low-FODMAP diet is one of the most widely recognized diets that may significantly improve IBS symptoms (4).

The acronym FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. They are a group of hard-to-digest short-chain carbohydrates (sugars) that can ferment in the colon, pull excess water into the bowel, and trigger flatulencei  The accumulation of gasses in the digestive system that results in belching and makes one pass wind through the anal passage. . This can result in abdominal pain, bloating, and diarrhea.

It is an elimination diet that temporarily excludes all high-FODMAP foods for 2 to 6 weeks to reduce IBS symptoms. These foods, then, are gradually reintroduced into the diet to determine which ones actually cause symptoms.

The following are the high-FODMAP foods to avoid on the IBS diet:

  • Fruits: Pears, peaches, apples, mangoes, nectarines, plums, and watermelon
  • Vegetables: Onions, broccoli, Brussels sprouts, asparagus, and artichoke
  • Legumes: Lentils, kidney beans, and chickpeas
  • Wheat products: Pasta, bread, and cereals
  • Artificial Sweeteners: Sorbitol, xylitol, mannitol, maltitol, and isomalt
  • Lactose: All lactose products (if you have lactose intolerance)

The following are low-FODMAP foods that you may eat on the IBS diet:

  • Fruits: Strawberries, blueberries, grapes, and oranges
  • Vegetables: Green beans, pumpkin, zucchini, eggplant, carrots
  • Lean Proteins: Skinless chicken, turkey breasts, eggs, cod, and halibut
  • Grains: Rice and quinoa
  • Lactose-Free Products: Lactose-free milk or alternatives like coconut, almond, or rice milk (if you have lactose intolerancei  A condition where the body cannot digest dairy sugars (lactose) due to the lack of the digestive enzyme lactase. )
protip_icon Pro Tip
Beware of FODMAP stacking. This is a condition where eating the same types of FODMAPs can clog the gut and worsen digestive symptoms. Avoid this by incorporating different types of food in your meals and ensuring a balanced diet.

The low-FODMAP diet is perhaps the most commonly known diet plan for IBS. However, gluten is another ingredient that must be avoided due to its close association with the condition. Scroll down to the next section to learn more about the gluten-free diet for IBS and how it works.

Gluten-Free Diet For IBS

The gluten-free diet

Gluten, a protein found in wheat and certain grains, is a potential irritant and is associated with multiple gastrointestinal disorders including IBS, celiac diseasei  A genetic autoimmune disease where gluten consumption causes inflammation in the lining of the small intestine. , Crohn’s diseasei  A type of chronic inflammatory bowel disease characterized by the swelling of the digestive tract that causes diarrhea and abdominal pain. , ulcerative colitisi  A type of chronic inflammatory bowel disease that causes inflammation in the colon and rectum and increases the risk of colon cancer. , and so on (5). It is hard to digest and can also generate peptidesi  Small amino acids that regulate various digestive functions such as food intake and gastric emptying. that negatively impact the digestive and the immune systems.

A 2016 UK study conducted on people with IBS found that the majority of the subjects showed a marked improvement in abdominal swelling, depression, and anxiety with a gluten-free diet within 6 weeks (6).

Therefore, eliminating gluten from your diet may play a significant role in managing IBS. The following are some gluten-containing foods to avoid:

  • Wheat
  • Barley
  • Rye
  • Pasta
  • Cereal
  • Bread
  • Crackers
  • Gluten-containing sauces
  • Malt vinegar
  • Beer

You can incorporate gluten-free versions of pasta, bread, crackers, etc., if you do not wish to give up on your favorite foods.

protip_icon Quick Tip
Structure your IBS diet journey into three simple phases – the elimination phase, where you exclude irritants from the diet; the reintroduction phase, where you add tolerable foods back into the diet; the personalization phase, where you create a diet plan tailored to your needs.

We have seen how dropping FODMAPs and gluten from your diet can ease your IBS symptoms. A natural consequence of eliminating whole food groups from your regular diet is weight loss. In the next section, we discuss how one can manage their weight effectively while on the IBS diet. Take a look.

IBS Diet For Weight Loss: Healthy Dieting Tips

IBS diet strategies are not intended for weight loss, although one may naturally lose weight due to the dietary restrictions. That said, these strategies are not recommended for healthy individuals intending to lose weight. However, individuals with IBS who wish to lose weight may adhere to the following to lose weight:

  1. Get An Individualized Plan: Consult your doctor or a dietician to customize a diet plan as they consider your food sensitivities, IBS symptoms, lifestyle, and weight loss goals.
  2. Practice Portion Control: Watch how much you eat while ensuring your body gets enough nutrition and energy. Frequent small meals spread throughout the day may be ideal.
  3. Have Balanced Meals: Ensure your meals have a good balance of whole grains, lean proteins, healthy fats, and vegetables.
  4. Take High-Fiber Foods: Introduce high-fiber foods into your diet gradually to promote proper digestion and curb your appetite. However, do not over consume insoluble fibers as they might trigger IBS symptoms.
  5. Exercise Regularly: Consult a physician to discuss an appropriate exercise regimen that helps manage your weight and treat IBS.
  6. Hydrate Yourself: Drink plenty of water and other tolerable fluids throughout the day for easy digestion, improved blood circulation, and to restore your body’s hydration levels.
  7. Manage Stress: Engage in mindfulness activities like yoga, meditation, or breathing exercises to reduce stress as it may otherwise trigger IBS symptoms and impact your weight (7), (8).

The above-mentioned steps make it possible for people with IBS to manage their weight healthily.

As IBS dietary modifications are constantly monitored, lifestyle changes must be adjusted accordingly. If you have just started with your IBS diet, observe its impact for a few weeks before gauging what works for you. In the next section, we have included a 30-day diet plan you can follow.
