I think you need to get a better understanding of what you're allergic to because it's fairly unlikely that an actual Sulfur allergy would ever create a problem with what you eat. Sulfur by itself is a crystalline chemical element that is not found in food.
Sulfa is a class of medications, based on Sulfoanamide that do not contain Sulfur but that commonly cause allergic reactions. If you are allergic to Sulfa medications you should avoid any sulfa-based medication but sulfa is not found in food.
Sulfites are a chemical compound naturally found in food, and added to food as a food preservative. Sulfites are most commonly found in wine (where they occur naturally but are also added as part of the fermentation process), dried fruit, dried potato products. If you are allergic to sulfites you should look for the worRAB sulfite, bisulfite, metabisulfite on food labels and should probably avoid fooRAB that contain them.
I hope that helps.
