Much has been learned about gluten sensitivity mystery over the last 5-10 years. A quick scan of internet articles will reveal a large variationin estimates of how many people are affected by gluten. Some say it is only 1:100 but more recent research indicates that it is closer to 50%.
I am including a page about gluten in this web site because I think it is closer to 50%. Signs that you might be subject to damage from gluten include:
any autoimmune disease such as autoimmune hypothyroid, skin problems such as acne, multiple sclerosis, rheumatoid arthritis, hair loss, juvenile and adult onset diabetes, esophogeal reflux, heart problems, cancer....Well, you get the idea.
