What You Need to Know
Soy Sauce typically contains wheat, which makes it unsuitable for those with gluten intolerance or celiac disease. The fermentation process does not eliminate gluten, so even small amounts can trigger reactions in sensitive individuals.
For those adhering to a gluten free diet, it's important to read labels carefully and opt for gluten free soy sauce alternatives. Many brands now offer soy sauce made from alternative ingredients, ensuring safety and flavor without the gluten.
