No Sulfite Zone

Once you figure out that you can not tolerate sulfites, you can start the business of finding out how to eliminate them and find a diet that works.  Of course, if you have multiple food allergies, you may have to accommodate the avoidance of  those also. Hope this helps make the searching a bit easier.
