? Frequently Asked Questions

4 questions
1 Can celiacs eat soy protein?
Yes, celiacs can generally eat soy protein safely. Soy is naturally gluten-free and is not one of the grains that contain gluten. However, it's important for celiacs to check labels carefully, as some soy products may be processed in facilities that also handle wheat or other gluten-containing ingredients. As long as the soy protein is certified gluten-free or processed in a dedicated gluten-free facility, it should be safe for celiacs to consume.
2 Does soy protein powder have gluten?
Soy protein powder is naturally gluten-free. However, cross-contamination during processing can sometimes occur. It's important to check the product label for any gluten-containing ingredients or cross-contamination warnings. To be certain, look for soy protein powders that are specifically labeled as gluten-free.
3 Why is soy sauce not gluten-free?
Soy sauce traditionally contains wheat as one of its main ingredients. The wheat provides proteins and starches that contribute to the fermentation process and final flavor. While there are gluten-free soy sauce alternatives made with rice instead of wheat, most standard soy sauces are not gluten-free. People with celiac disease or gluten sensitivity should be cautious and check labels carefully when consuming soy sauce.
4 Can celiacs have hydrolyzed soy protein?
Hydrolyzed soy protein is generally considered safe for most people with celiac disease. The hydrolysis process breaks down the protein into smaller components, which typically eliminates the gluten content. However, it's important for celiacs to check product labels carefully, as some hydrolyzed soy proteins may be derived from wheat or processed in facilities that handle gluten-containing ingredients. If in doubt, individuals with celiac disease should consult their doctor or a registered dietitian for personalized advice.
