Navigating Fast Food and Dining Out Options on Low FODMAP diet

Lowering your intake of FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyol) carbs has been associated with an improvement in irritable bowel syndrome (IBS) and small intestinal bacterial overgrowth (SIBO). If you’re someone who eats out a lot you need to learn what foods may trigger symptoms. Learning how to spot low FODMAP fast food options can help make eating out fun again.

What is the Low FODMAP Diet (LFD)

FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are a type of carbohydrates that have shorter chemical bonds. In food they exist as the following:

  • Fructose is found in fruits and some vegetables

  • Raffinose is a type of sugar in beans

  • Stachyose in legumes and root vegetables

  • Lactose in dairy

  • Sugar alcohols (sorbitol, mannitol, xylitol, maltitol)

Low FODMAP diets (LFDs) are diets that restrict the amount of FODMAPs to less than 3.1 grams per day. Regular diets will have a total intake of 15 to 30 grams of FODMAPs per day. So this is a significant decrease in the intake of FODMAPs.

These restrictions usually last from four to eight weeks. Then the foods are reintroduced as they are tolerated. This diet should be done under the supervision of a registered dietitian.

The following foods are avoided on these diets:

  • Cereal grains (wheat, barley, rye)

  • Legumes (lentils, beans, chickpeas, soy, peas)

  • Some nuts (cashews and pistachios)

  • Vegetables (artichokes, asparagus, cauliflower, garlic, leeks, mushrooms, onions, scallions, shallots, snap peas, snow peas, avocado)

  • Fruit (apples, apricots, Asian pears, blackberries, cherries, figs, jackfruit, mangoes, nectarines, peaches, pears, persimmon, plums, prunes, tamarillo, watermelon, white peaches, grapes)

  • Dairy (regular milk, ice cream, soft cheeses, yogurt)

  • Honey

  • Foods with added fructose, high fructose corn syrup

  • Sugar alcohols and foods with sugar alcohols mannitol, xylitol, isomalt, and sorbitol (sugar-free foods, chewing gums, mints)

Typically, low FODMAP diets are also gluten and lactose-free. However, getting minimal gluten may not be a problem depending on a person's medical history.

Low FODMAP Diet for IBS, SIBO, and Constipation

Some people have trouble digesting FODMAPs. Especially those who have irritable bowel syndrome (IBS), constipation, and/or small bacterial intestinal overgrowth (SIBO).

Consuming more low FODMAP foods may combat symptoms of these conditions. That is why a diet low in these foods is recommended.
