Is soy sauce low FODMAP?
The answer is yes - most regular soy sauces are low FODMAP in typical servings.
But there are important exceptions.
Why Soy Sauce Can Be Low FODMAP
Soy sauce is made through fermentation.
During this process, many fermentable carbohydrates are broken down.
This reduces FODMAP content.
Monash University explains that fermentation can reduce FODMAP levels in certain foods.
This is why soy sauce is often tolerated.
When Soy Sauce May Cause Problems
Some soy sauces contain:
- added garlic
- added onion
- sweeteners

These additions can trigger symptoms.
Always check ingredients carefully.
