Here's TMI on gluten!
I do not have a gluten disease but am allergic/reactive to gluten. So is my wife, so we do not eat it. This is the reason I quit drinking beer and started making wine!
Lalvin yeasts are certified gluten free. I don't know about other brands. Unless you are making a wine from wheat or other grain that contains gluten, you will be safe. Use only the yeasts certified gluten free.
For those who are sensitive, gluten provokes an inflammatory response. Many many people are suffering from "allergies" or "arthritis" or "irritable bowel syndrome" when what they really are is allergic to gluten. It is many times more common than Celiac or Graves, the more serious diseases involving gluten. It is possible to be quite sensitive to gluten and yet not fall into one of those clinical diagnoses.
One theory is that many Baby Boomers were sensitized early on in life because during that period of the 1940s-1950s when they were infants and toddlers, it was advised to feed them solid foods containing gluten much earlier than is now the practice. This theory postulates that this early feeding of solid foods containing gluten sensitized their intestines to it. I think it was in the mid-70s that the newer guidelines that hold off on solid foods for babies longer were adopted.
Since I eliminated it, I do not have the joint and muscle aches that used to plague my everyday life. My lungs and nose are clearer and HUGELY less stuffed up. When I do eat something with gluten, the symptoms return. It is so easy now to eliminate it, since so many foods have been made with gluten-free formulations. It just makes restaurant eating a challenge.
