This pilot study demonstrates a major problem for those following a gluten free diet. A random test showed that as high as 41% of shelf based products had enough gluten cross contamination to create a health problem for those with gluten intolerance. Gluten Free Society has always recommended avoiding packaged processed foods for the following reasons:
You cannot control what manufacturers will put in their products.
Packaged processed foods are contradictory to good health. (Considering that going gluten free is a mandatory decision to restore health, processed gluten free products will not help you achieve this)
Cross contamination is a major issue.
The so called “gluten free” grain substitutes have not been adequately studied to be recommended as staple foods in the diet, and many studies show them to be detrimental for those with celiac disease.
Don’t fall into the false mindset that eating processed foods labeled “gluten free” are actually gluten free. Don’t think that eating unhealthy processed food is going to help you re-establish or maintain your health.
