Foodfacts.com is a GREAT web site! I just found it and I already love it! At the top of the webpage is a search engine. You can search for any brand food, or food type and using the keywords you type in, it brings up a list of foods. Find the food you're looking for and click on it. And for that food it shows you what's good about it, what's bad about it, its ingredients, and its allergens. Amazing!!
Or you can click on the allergen you want to avoid and it brings up foods that are free from that allergen.
I bookmarked it. And I also downloaded the iPhone app. It's amazing!
Go to their web site and give it a try!
