Unveiled: the truth about soy sauce and fodmaps

Soy sauce, a staple in Asian cuisine, is a fermented condiment made from soybeans, wheat, and salt. For individuals following a low-Fodmap diet, it’s crucial to know whether soy sauce is compatible with their dietary restrictions. This blog post delves into the Fodmap content of soy sauce and provides practical guidance for incorporating it into a low-Fodmap lifestyle.

Understanding Fodmaps

Fodmaps are fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These short-chain carbohydrates are poorly absorbed in the small intestine and can cause digestive symptoms such as gas, bloating, and diarrhea in individuals with irritable bowel syndrome (IBS) and other functional gastrointestinal disorders.

The Fodmap Content of Soy Sauce

The Fodmap content of soy sauce varies depending on the brand and fermentation process. Traditional soy sauce, which undergoes a long fermentation period, contains low levels of Fodmaps. However, some commercially produced soy sauces may contain added high-Fodmap ingredients, such as wheat or corn syrup.

According to the Monash University Low-Fodmap Diet App, 1 tablespoon (15 ml) of traditional soy sauce is considered low-Fodmap. However, it’s important to check the ingredient list carefully to avoid brands that contain high-Fodmap additives.

Choosing Low-Fodmap Soy Sauce

When choosing soy sauce for a low-Fodmap diet, look for the following:

• Traditional fermentation: Soy sauce that has been fermented for at least six months is likely to have lower Fodmap levels.
• Low-Fodmap ingredients: Avoid soy sauces that contain added ingredients such as wheat, corn syrup, or garlic.
• Check the label: Read the ingredient list thoroughly and look for the Monash University Low-Fodmap Diet App logo to ensure that the product is certified low-Fodmap.

Incorporating Soy Sauce into a Low-Fodmap Diet

While traditional soy sauce is generally low-Fodmap, it’s important to use it in moderation. Start with small amounts and gradually increase the quantity as tolerated.

Here are some tips for incorporating soy sauce into a low-Fodmap diet:

• Use it as a dipping sauce: Soy sauce can be used as a dipping sauce for sushi, sashimi, or grilled meats.
• Add it to stir-fries: A small amount of soy sauce can enhance the flavor of low-Fodmap stir-fries.
• Marinate meats: Soy sauce can be used as a marinade for low-Fodmap meats, such as chicken or tofu.
• Season soups and sauces: Soy sauce can add a savory flavor to low-Fodmap soups and sauces.

Low-Fodmap Soy Sauce Alternatives

If traditional soy sauce is not tolerated, there are several low-Fodmap alternatives available:

• Tamari: A gluten-free soy sauce made from soybeans and water.
• Coconut aminos: A naturally sweet sauce made from fermented coconut sap.
• Liquid aminos: A soy sauce substitute made from soybeans and water, without the fermentation process.
• Fish sauce: A fermented sauce made from fish and salt.

Summary: Navigating Soy Sauce in a Low-Fodmap Diet

Soy sauce can be a valuable addition to a low-Fodmap diet, provided it is used in moderation and carefully selected. By choosing traditional soy sauce with low-Fodmap ingredients, individuals with IBS and other functional gastrointestinal disorders can enjoy the savory flavors of Asian cuisine without triggering digestive symptoms.
