Wondering, “is mustard low FODMAP?” I was about to take a bite of my hotdog when this question popped up in my head. The answer to, “Is mustard low FODMAP” is yes but it depends.
Like a lot of foods on the IBS low FODMAP diet, mustard comes with some fine print. There are a few different types of commercial mustards like dijon, regular yellow mustard and fancy whole grain mustard. All of which are low FODMAP in small serving sizes UNLESS they contain high FODMAP ingredients.
To identify those and walk out of here with some mustardy recipes, stick around while we go through these topics:

First things first, what is mustard and how is it made?
What Is Mustard Made From?
The yellow condiment we all know and love (or hate) is made from a plant. The mustard plant has yellow flowers and is part of the Brassicaceae family.
Mustard seeds are a spice used in lots of South and Southeast Asian dishes like this low FODMAP slow cooker lamb curry.
Those mustard seeds are grinded with water, vinegar and other ingredients to create yellow mustard. In theory, mustard is low FODMAP because water is not a problem, most if not all vinegar is low FODMAP but what about those other ingredients used?
Is Mustard Low FODMAP?
Condiments can be tricky on the IBS low FODMAP diet because of ingredients like garlic, onion, high fructose corn syrup and all those other pesky high FODMAP ingredients used in commercial goods.
Monash University has tested several types of mustard and they are low FODMAP in small amounts. Even with regular yellow mustard, the app states, “read ingredient labels carefully and limit intake if onion, garlic or other high fodmap ingredients are added.”
All information below is based on Monash University’s low FODMAP App.
Yellow Mustard (American)
Is mustard low FODMAP? Yes, mustard is low FODMAP at 1 tablespoon or 11 grams. Just make sure there’s no onion or garlic powder in it. Sometimes this can be labeled as “spices” in the ingredients list.
My favorite way to use mustard is actually covering a whole roast for low FODMAP roast chicken. It’s my French mother in law’s recipe and it transforms a regular holiday chicken to another level.
Mustard, Mild (European)*
The app listed mild yellow mustard low FODMAP at 30 grams or 2 tablespoons.
*The low FODMAP App had mustard, mild with a German flag next to it. I didn’t think much of it until I remembered trying European (Dutch) mustard and realizing how different it was from the regular American Heinz mustard I had growing up.
Mustard seeds FODMAP serving size is 2 grams or 1 teaspoon. That may not seem like a lot but it’s actually plenty because mustard seeds are used sparingly in Indian curries.

Is dijon mustard low FODMAP? Yes, dijon mustard is low FODMAP at 1 tablespoon or 23 grams. Dijon mustard is sharp French mustard that is tolerated by most individuals with IBS.
Larger serves ¾ cup, 230 grams or 8.1 ounces contains moderate fructans and GOS.
Mustard (Whole Grain)
Is whole grain mustard low FODMAP? Yes! Whole grain mustard is low FODMAP at 1 tablespoon or 20 grams. This ingredient contains trace amounts of FODMAP but was issued an “eat according to appetite” label on the app.
Are mustard greens low FODMAP? Unfortunately, mustard greens have not been tested by Monash yet. The Spoonful App states they are likely low FODMAP at 1 serving.
Mustard greens aren’t from the same plant as mustard seeds. They are a leafy green of a type of mustard plant. For some reason, mustard greens are often confused with collard greens.
Collard greens on the other hand have been tested and are low FODMAP at 1 serve (1 cup, 36 grams or 1.3 ounces).

9 Other Low FODMAP Condiments
This section will give you a quick overview of some low FODMAP condiments you can enjoy on a low FODMAP diet.

Mayonnaise is low FODMAP at 2 tablespoons. This condiment is made from mainly eggs, lemon juice or vinegar, vegetable oil and occasionally seasonings.
Like mustard, some products may contain garlic or onion powder listed as ‘natural flavors’ or ‘spices’. Check the ingredient list carefully and if you’re really worried: call or email the manufacturer to find out what ‘natural flavors’ or ‘spices’ are.
Try making these low FODMAP mayonnaise recipes:

But the generic BBQ listing includes a “limit intake if onion, garlic and other high FODMAP ingredients have been added.” We all know that BBQ sauce contains those two flavorings, so in this case: eat according to your tolerances.
Hot sauce should be low FODMAP if the ingredients are simply hot chiles, vinegar and salt. Some hot sauces may contain onions. The FODMAP app doesn’t have a hot sauce listing but three main options do come up:
- Sriracha chili sauce is low FODMAP at 5 grams or 1 tablespoon.
- Habanero Sauce (Red) has a low FODMAP serving size of 10 grams or 1 teaspoon.
- Habanero Sauce (Green) is low FODMAP at 8 grams or 1 teaspoon.
Both habanero sauces came with warnings to limit intakes. Some products tested contained small amounts of onions. Limit intake to small serves and be careful because each product has different amounts of onions.
- Red Habanero sauce: amounts larger than 20 grams or 0.7 ounces contain high amounts of fructans.
- Green Habanero sauce: contains capsaicin which triggers heartburn and abdominal pain in individuals with IBS.
Eat hot sauce according to your tolerances.
Shrimp in cocktail sauce is the only time I can think of cocktail sauce. It’s hard to find a low FODMAP one on the shelves but with a lot of other condiments, small intakes of this condiment should not trigger IBS symptoms.
