Hidden FODMAPs in Packaged Foods: Where They Show Up

Our guide to reading labels explains which ingredients to look for. This article takes the opposite approach and shows you which types of product are most likely to contain them, so you know where to be careful before you pick anything up.

Stocks, broths, and soups

Most commercial stock, bouillon cubes, and ready-made soups contain onion, garlic, or both, often as powder. Even products labeled "low sodium" or "organic" are usually flavored this way. Look for stock specifically labeled as free of onion and garlic, or make your own from meat, carrots, and herbs.

Sauces, condiments, and dressings

• Pasta and pizza sauce: nearly always contains onion and garlic.
• Ketchup and barbecue sauce: may contain onion or garlic powder, and often high fructose corn syrup.
• Salad dressings: frequently contain garlic, onion, or honey.
• Marinades and stir-fry sauces: often built on garlic and onion.
• Mayonnaise and mustard: usually fine, but check the label for "spices" and garlic.

Snack foods and seasonings

Flavored chips, crackers, popcorn, and nuts are a common surprise. Barbecue, sour cream and onion, ranch, and "savory" flavors all rely on onion and garlic powders. Plain, lightly salted versions are usually safer.

Bars and "healthy" snacks

Protein bars, granola bars, and meal-replacement products often include inulin or chicory root fiber to boost fiber, honey or agave as a binder, dried fruit, and sugar alcohols such as sorbitol or maltitol. Several of these may be present in the same bar.

Deli meats, sausages, and plant-based meat

Processed meats are commonly seasoned with garlic and onion. Plant-based burgers, nuggets, and sausages add further risk, because they may use soy protein, pea protein concentrates, or legume flours, along with the same seasonings.

Gluten-free and "better for you" products

As we explain in FODMAP vs. gluten, a gluten-free label does not mean a product is low FODMAP. Gluten-free breads, wraps, and cereals can contain inulin, honey, or high FODMAP flours. The same applies to products marketed as keto, high fiber, or low sugar.

Dairy alternatives

Plant milks and yogurts vary widely. Some contain added inulin or sweeteners, and some, like soy milk made from whole soybeans, are higher in FODMAPs. Always check the ingredient list instead of relying on the front of the package.

Drinks

Fruit juices, especially apple and pear, are high. "Zero sugar" drinks and flavored waters may use polyols. Some smoothies and protein shakes contain inulin or high FODMAP fruit.

A short checklist

1. Be most careful with soups, sauces, flavored snacks, bars, and processed meats.
2. Choose the plainest version of a product when you can.
3. Scan for garlic, onion, inulin, chicory root, honey, high fructose corn syrup, and ingredients ending in "-ol."
4. Treat "spices" and "natural flavors" as a possible source if you react to an otherwise safe product.
5. Build a short list of products that work for you and reuse it.
