One of the reasons my family and I joined
DVC is because of food allergies. My two DDs (6 and 3) have severe food allergies -- one to peanuts, the other to tree nuts -- and WDW is one of the few places where I feel safe.
I wholeheartedly suggest that you contact WDW directly about the food in the parks and restaurants. I usually sent an email a few weeks before leaving asking for advice and in return they send a form letter with general food prep info, and a list of the food and beverage managers for each park's phone numbers. Absolutely call those numbers (sometimes they'll be a few rounds of phone tag) and ask your questions. I ask them to email any info they have (which usually consists of ingredient lists, etc.), print them out and bring them to the parks.
Here are some random pieces of advice for you:
* Be sure to include your child's food allergies on any ADR's you make. This allows the chefs and their kitchens to be prepared for your family's food limitations. Re-state your allergies before being seated as well. The chef will come out of the kitchen and go over the menu with you pointing out which dishes will be safe. Sometimes, they even prepare special desserts ahead of time. This is such an unbelievable treat for my DDs. Dessert is usually the toughest for them.
* Be especially careful in Epcot World Showcase eateries. The language barrier can sometimes be problematic.
* Check out the DisAbilities board here. There are several fairly recent threads relating to food allergy and eating safely at WDW.
On the whole, WDW is extremely cautious about food allergies. They are quite serious about it and I have had nothing but complete cooperation from the food service staffs both in and out of the parks.
Have a great trip.
