Frequent Asked Questions

Q: Are any San-J products certified FODMAP Friendly?

Q: What is gluten?


Gluten refers to the proteins found in wheat, rye and barley. The consumption of gluten in these products adversely affects the health of those with celiac disease and gluten intolerance.

Q: What is celiac disease?


Celiac disease is a digestive and autoimmune disorder that is triggered by eating gluten. When gluten containing foods are consumed, damage occurs to the lining of the small intestine, making it difficult for the body to absorb nutrients. It is estimated that around 3 million or 1 out of every 133 people in the United States have celiac disease. There is no cure for celiac disease, but the condition can be managed with diet by removing all gluten containing foods.

Q: Who follows gluten free diets and what are the benefits?


For people with celiac disease, the only way to manage the condition is to follow a gluten-free diet. Through adherence to a gluten-free diet, the small intestine will begin to heal and the overall health of the affected individual should improve.

Gluten-free diets may also be followed by those who feel their overall health improves when avoiding gluten laden foods.

Q: How do San-J products fit into a gluten free diet?

Q: What steps does San-J take for gluten free products?


San-J does not add any gluten ingredients to San-J gluten free products. We understand the sensitive nature that exists for those who suffer from gluten intolerance or Celiac Disease. Since our facilities processes other products containing wheat, San-J has implemented specific sanitation methods in an effort to prevent cross contamination of wheat in our gluten free products. In addition, we test each batch of gluten free products for the presence of gluten. Samples are also periodically sent to an outside laboratory as means of confirming the reliability of our tests.
The FDA regulation sets a threshold for gluten of less than 20 parts per million in foods that are labeled "gluten-free," “no gluten,” “free of gluten,” and “without gluten.” San-J gluten free products are certified gluten free by the Gluten Free Certification Organization and we follow their guidelines of less than 10 ppm. All San-J Tamari Soy Sauces are tested at less than 5ppm.
