<<Disclaimer: Verify this information before applying it to your situation.>> I e-mailed Sargento asking for their GF cheese. Here is their response. They answered me as soon as the day after. We are pleased to tell you that most Sargento natural cheeses should be acceptable to a gluten-free diet. There are a few exceptions. Sargento Shredded Imitation Mozzarella Cheese contains a modified food starch which may contain gluten. We would also not recommend that anyone on a gluten-free diet eat our Shredded Taco Cheese, our Shredded Nacho & Taco Cheese, or our 6 Cheese Zesty Mexican Recipe Blend. There is wheat flour in the spice mixture in these products. For obvious reasons, we would also not recommend our MooTown Snacks Cheeze & Sticks, Cheese & Pretzels, Cheeze & Crackers, or Cookies & Creme. You will notice that we use microcrystalline cellulose as an anti-caking agent on most of our shredded cheeses. When added to shredded cheese, cellulose prevents the shreds from sticking together. Microcrystalline cellulose is a white, odorless, tasteless, totally natural powder made from cellulose, a naturally occurring component of most plants. It is not derived from wheat, oats, barley, or rye. We hope this information is helpful. If you have questions about how our products may affect your medical condition, we suggest you discuss this information with your physician.
