Maybe you’ve started to notice a pattern. You love to cook with onions, but each time you eat foods prepared with them your stomach is upset. You feel bloated, gassy, and in some cases, really ill.

Other foods may also be causing you digestive distress: garlic, apples, breads made with wheat, certain nuts. Keeping a food diary can help narrow down which foods seem to be causing you problems, but a visit to the doctor may confirm what may be the underlying issue: your irritated system can’t easily digest what the experts call FODMAPs.

What are FODMAPs?

FODMAP is an acronym for a type of carbohydrate, or sugar, found in certain foods. The acronym is a scientific mouthful: Fermentable Oligo-Di-Monosaccharides and Polyols. These carbohydrates, if not easily absorbed as they move through the intestines, can be rapidly fermented by bacteria in the gut, resulting in symptoms ranging from a feeling of fullness to nausea or pain.  The FODMAPs are:

  • Fructose: found in honey, certain fruits, high-fructose corn syrup
  • Lactose: dairy products
  • Fructans: garlic, onion, wheat (fructans is also known as inulin)
  • Galactans: legumes, such as lentils, chickpeas, soy
  • Polyols: stone fruits, such as avocado or peaches; artificial sweeteners with sorbitol, mannitol, xylitol

A low-FODMAP diet is not a long-term solution to chronic digestive issues, like irritable bowel syndrome. Rather, it’s a short-term option, allowing time for the irritated system to calm down.

If your health care provider recommends that you consume foods low in FODMAPs, the diet typically lasts two to six weeks, before slowly reintroducing higher FODMAP foods, one at a time, to your tolerance. Why add them back? It’s because foods high in FODMAPs have nutritional benefits, as part of a well-balanced diet.

Foods low in FODMAPs

Plenty of fruits, vegetables and other foods are intestine friendly, or low in FODMAPs:

  • Fruits: blueberries, kiwi fruit, grapes, oranges, strawberries, melons
  • Vegetables: carrots, celery, leafy greens, spinach, squash, tomatoes, white and sweet potatoes, other root vegetables
  • Other foods: all meats, grains made with gluten-free/spelt grains (rice, oats, quinoa), eggs, maple syrup, all fats, most spices and herbs, vinegars, olive oil

Need meal ideas? Your doctor may provide you with snack and meal suggestions. Registered dieticians are also a good resource for low-FODMAP recipes.

Tips while eating low-FODMAP diet

Experts suggest these tips for those on a temporary low-FODMAP diet:

  • Ensure you’re getting enough fiber. Your doctor may suggest that you take a prebiotic fiber supplement, usually in powder form and easily dissolvable in liquids.
  • Pay attention to serving sizes. Avoid consuming too many low-FODMAP foods in one sitting, which can add up to too many FODMAPs.
  • Read food labels. Avoid foods with high-fructose corn syrup, honey, inulin, wheat and soy. However, if these ingredients are at the end of the ingredients list, the food could be considered low in FODMAPs.
  • Drink plenty of water.
