Frequently Asked Questions

https://www.pexels.com/photo/white-ceramic-bowl-on-newspaper-4281752/
Is gluten-free soy sauce safe for people with celiac disease?
Although most certified gluten-free soy sauces are safe for people with celiac disease, you should always look for third-party certifications, review the ingredients and look for cross-contamination risks.
What’s the difference between traditional soy sauce and tamari sauce?
Conventional soy sauce contains wheat and is not safe for those with gluten sensitivities and intolerances. Conversely, tamari sauce is brewed with little to no wheat, making it a much better alternative.
Can you replace soy sauce with coconut aminos in recipes?
You can easily swap out soy sauce for coconut aminos in equal amounts. However, you should expect your dish to have a somewhat sweeter and less salty taste.
Are there low-sodium, gluten-free soy sauces available for purchase?
Typically, Japanese soy sauce brands contain a lot of sodium per serving, while American brands can be even higher. If you’re looking to reduce your sodium intake, brands like SAN-J have low-sodium gluten-free options.
Making the Best Gluten-Free Choice for Your Kitchen
While flavor and quality are important when selecting a gluten-free soy sauce, safety is the most critical criterion. Choose a brand that clearly states its certifications and reputation so you can confidently create meals that align with your tastes and health needs.
