Editor: A friend of mine has family members with celiac disease. Concerned that crumbs could be transferred from one toaster to the other, she keeps two in her kitchen. This is a common practice in families dealing with severe celiac issues, and the approach is understandable. In her situation, the grandson has to be rushed to the emergency room if he consumes gluten.
New research may put some minds at ease related to gluten transfer in the kitchen for the toaster, knives, and possibly even pasta cooking water.
