Hi Cassidy,

Terrific article! Any chance I could trade emails with someone in your QA Lab familiar with the R5 ELISA testing? It has become an issue of interest to us recently; we would like to learn a little bit about the testing protocol to explore the possibility of performing the assay in-house. If it would be possible to ask a few general questions I’d be grateful!

To Whom It May Concern,

Why is it that per the following statement from within this blog post, you claim to perform advanced testing to confirm that your grain is non-GMO, yet many of your products to not state this on your label? Example: Your gluten-free Pancake Mix which contains Corn Flour and Corn Starch?

I was so disappointed when my family consumed this mix this morning as we have vehemently avoided GMOs exclusively for almost a decade now.

Hi, just checking with you re: how natural is the process. I learned potassium bromate is used in most flours during processing. Can you enlighten me as to if your company uses this ingredient in any of it’s flours? I have a pre-cancerous condition, and I need to really watch what I consume.
Thanks so much for your time,

No, our flours have not been bromated. Please feel free to call us at 800-349-2173 if you have further questions.
