Fructans and flavor bases
Inulin, chicory root fiber, fructooligosaccharides, onion, garlic, wheat-based ingredients, and vague seasoning blends are common first-pass clues in bars, sauces, soups, and savory snacks.

Low FODMAP Ingredient Checker
A low FODMAP ingredient checker or FODMAP checker works best as a triage tool: quickly screen products, flag ingredients that deserve review, and connect the label to a more detailed IBS-friendly guide when the answer is not obvious.
Quick answer
A low-FODMAP ingredient checker can flag common label clues such as inulin, chicory root, onion, garlic, honey, and polyols. It cannot calculate a product's total FODMAP dose or replace Monash serving data, so portion size, elimination phase, and personal tolerance still matter.
What It Catches
- Sweeteners, fibers, thickeners, and flavoring patterns that low FODMAP shoppers often review.
- Products that need portion-size or reintroduction context instead of a simple yes-or-no label answer.
- Ingredient profiles connected to IBS label-reading workflows.
Workflow
- 1.Scan the label and look for flagged ingredients before comparing serving sizes.
- 2.Review whether the concern is an ingredient, portion threshold, or personal tolerance issue.
- 3.Open the low FODMAP guide when a product needs a deeper explanation.

What the scan should help you review
Polyols and sweeteners
Sorbitol, mannitol, maltitol, isomalt, and xylitol can be important, while erythritol is assessed differently. The ingredient list still does not reveal the quantity used in a serving.
Serving size and phase
A flagged ingredient is not a complete verdict because FODMAP effects are dose-dependent. Compare the package serving, Monash guidance, and your elimination or reintroduction plan.
Decision boundary
IngrediCheck screens declared ingredients against the low-FODMAP rules you save; it does not test a finished product, calculate stacking across a meal, or diagnose IBS. Use the result to focus label review during ordinary packaged-food shopping, then make portion, meal-stacking, symptom, and reintroduction decisions with authoritative dietitian or Monash guidance for your current phase.

Ingredient profiles
sweetenerIngredient profile
Erythritol
Erythritol is a low-calorie sugar alcohol used in keto products, protein snacks, tabletop sweeteners, and reduced-sugar beverages. It is popular because it adds sweetness without behaving like table sugar in every nutrition panel.
thickenerIngredient profile
Xanthan gum
Xanthan gum is a fermentation-derived thickener that shows up in gluten-free baking, sauces, dressings, and frozen desserts. It is often the ingredient that gives wheat-free products enough structure to hold together.
proteinIngredient profile
Gluten
Gluten is the protein network that gives wheat-based dough elasticity, chew, and structure. It matters to label readers because avoiding gluten is not just about bread; it is about derivatives, cross-contact, and reformulation drift across packaged foods.

Sweeteners ending in -ol, inulin, chicory root fiber, wheat-based ingredients, onion, garlic, and vague flavoring language are common review points.
Should low FODMAP users scan every packaged food?
