FODMAPs, or Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols, are a group of carbohydrates that can cause digestive issues in some individuals. Understanding What Are High Fodmap Foods is crucial for managing conditions like Irritable Bowel Syndrome (IBS) and improving overall gut health. This guide provides a detailed overview of high FODMAP foods to avoid and low FODMAP alternatives to enjoy.
Why FODMAPs Matter for Digestive Health
FODMAPs are poorly absorbed in the small intestine. When they reach the large intestine (colon), they draw in water and are fermented by gut bacteria. This fermentation process produces gas, which, combined with the extra water, can lead to uncomfortable symptoms such as bloating, abdominal pain, gas, and diarrhea.
While most people can tolerate FODMAPs without issue, individuals with IBS or other digestive sensitivities often experience exacerbated symptoms after consuming high FODMAP foods.
The main types of FODMAPs include:
- Oligosaccharides: Fructans (found in wheat, onions, garlic) and galactans (found in beans and legumes).
- Disaccharides: Lactose, the sugar found in dairy products.
- Monosaccharides: Fructose, the sugar found in fruits, honey, and high-fructose corn syrup.
- Polyols: Sugar alcohols like sorbitol and mannitol, found naturally in some fruits and vegetables and used as artificial sweeteners.

Identifying What Are High FODMAP Foods: A Detailed List
For individuals with IBS or other digestive sensitivities, understanding what are high FODMAP foods can provide relief from uncomfortable symptoms. A FODMAP diet involves limiting or avoiding these foods and emphasizing low-FODMAP alternatives. Here’s a comprehensive breakdown of high-FODMAP foods to be mindful of:
1. High Fructose Fruits
Many fruits contain fructose, a monosaccharide. Some fruits contain fructose in excess of glucose, making them high in FODMAPs. Others contain sorbitol, a natural sugar alcohol. It’s not necessary to avoid all fruits but understanding what are high FODMAP foods in this category is helpful:
- Apples
- Apricots
- Blackberries
- Cherries
- Mangoes
- Nectarines
- Peaches
- Pears
- Plums and prunes
- Pomegranates
- Watermelon
- Canned fruit in syrup
- Dried fruit
2. Vegetables High in FODMAPs
Certain vegetables, particularly garlic and onions, are notoriously high in FODMAPs. Even small amounts can trigger symptoms. Be aware of these high FODMAP vegetables:
- Garlic
- Onions (including scallions and leeks)
- Artichokes
- Asparagus
- Beets
- Brussels sprouts
- Cabbage
- Cauliflower
- Mushrooms
- Okra
- Peas
- Snow peas
- Sugar snap peas
3. Grains Containing High FODMAPs
Many common grains contain fructans, an oligosaccharide. If you are sensitive to FODMAPs, be careful of these grains:
- Wheat (bread, pasta, cereals)
- Barley
- Rye
- Couscous
- Semolina
- Farro
4. Dairy Products with Lactose
Dairy products often contain lactose, a disaccharide that can cause problems for some individuals. Here are dairy products to avoid or limit:
- Milk (cow, goat, sheep)
- Buttermilk
- Cream
- Custard
- Ice cream
- Margarine
- Soft cheeses (cottage cheese, ricotta)
- Yogurt (regular and Greek)
5. Legumes High in Galactans
Beans and legumes contain galactans, an oligosaccharide. Most beans fall into the high-FODMAP category:
- Baked beans
- Black-eyed peas
- Butter beans
- Chickpeas
- Lentils
- Kidney beans
- Lima beans
- Soybeans
- Split peas
6. Sweeteners Containing Polyols
Certain sweeteners contain polyols, a type of sugar alcohol that is poorly absorbed in the digestive tract. Be aware of these sweeteners:
- Agave
- Fructose
- High-fructose corn syrup
- Honey
- Isomalt
- Maltitol
- Mannitol
- Molasses
- Sorbitol
- Xylitol
7. Processed and Marinated Meats
While meat, poultry, and fish themselves are naturally low in FODMAPs, processed and marinated meats may contain high-FODMAP ingredients like garlic, onion, or high-fructose sweeteners. Always check labels carefully.
8. Certain Nuts and Seeds
Most nuts and seeds are low in FODMAPs. However, cashews and pistachios are notable exceptions and should be avoided on a low-FODMAP diet.

Working with a Dietitian for a Balanced Low-FODMAP Diet
Embarking on a low-FODMAP diet can be challenging. It’s highly recommended to work with a registered dietitian (RD) or registered dietitian nutritionist (RDN) who specializes in gastrointestinal disorders.
A dietitian can help you:
- Identify hidden sources of FODMAPs in your current diet.
- Create a personalized meal plan that meets your nutritional needs while adhering to low-FODMAP guidelines.
- Ensure you are getting enough dietary fiber, which can be challenging on a restricted diet.
- Guide you through the reintroduction phase, where you systematically reintroduce high-FODMAP foods to identify your specific triggers.
Your primary healthcare provider can also offer guidance and ensure that the low-FODMAP diet is safe and appropriate for your individual health needs.
Conclusion: Taking Control of Your Digestive Health
Understanding what are high FODMAP foods and making informed dietary choices can significantly improve your digestive health, especially if you have IBS or other digestive sensitivities. While avoiding high-FODMAP foods might seem daunting initially, the potential relief from uncomfortable symptoms is well worth the effort. Remember to consult with a healthcare professional or registered dietitian to create a personalized plan that works best for you. By identifying your triggers and making mindful food choices, you can take control of your digestive health and improve your overall quality of life.
