So, let’s dive,
What Is Soy Sauce?
Soy sauce is a type of liquid seasoning made from fermented soybeans, wheat, salt, and water. It is very commonly used in Asian cooking. You’ll find it in many dishes, from sushi rolls to stir-fried veggies.
There are a few types:
Regular soy sauce – contains both soy and wheat
Gluten-free soy sauce – made without wheat (often called tamari)
Low-sodium soy sauce – less salt but same ingredients
Each type may affect digestion differently.
Is soy sauce low FODMAP?
Here’s the good news: Is soy sauce low FODMAP? Yes, in small amounts, it is!
Monash University says regular soy sauce is low FODMAP in small amounts—just 1 tablespoon (20 ml). So you should try it and enjoy it in small amounts.
Why Is It Considered Safe?
The fermentation process breaks down FODMAPs
Wheat in soy sauce is minimal and doesn’t cause issues for most
Salt helps preserve the sauce and does not raise FODMAP levels
So, if you use a small amount, it’s safe for most people with IBS.
Is Soy Sauce Okay for IBS?
Good news—both regular and gluten-free soy sauce (tamari) are low FODMAP in small amounts. That means most people with IBS can enjoy them without issues.
Why it works:
Fermentation breaks down the problematic parts of soybeans
Though wheat is technically an ingredient, the amount in soy sauce is minimal enough that it rarely causes issues
So, Tamari is made without wheat, so gluten isn’t even an issue.
But here’s the catch: IBS is unpredictable. Some individuals still react.
Smart way to test it:
Try just 1 teaspoon at first
Wait a day to see how your gut feels
If it’s all good, you can slowly use more
The key? Moderation. Stick to recommended serving sizes (about 1 tablespoon max) and you’ll likely be fine.
