Reading labels is part of celiac. I use Ralph's and Oscar Myer bacon but not Farmer John as it has wheat. I love corn tortillas that are labeled gluten free and use them with hot dogs, pastrami, burgers, and peanut butter. Lays plain chips are gluten free as are some other plain ones. Rice and popcorn cakes are good but most have food starch in them that may have gluten.
Fast food is a killer for me. McDonald's is the worst restaurant for allergic people. They have dedicated friers but would not trust them, Read the online info on fast food places you go to. I only eat at In n Out right now.
WDW and DLR are excellent with dealing with allergies. CMs do need to be reminded as allergens can be overlooked. At a local restaurant I had the chef scrape the coating off the fish and reserve it then another time he ripped the bread off the meat and served it that way with bits of bread stick stuck on it. Not everyone understands cross contamination or that soy sauce has wheat and the whey is a dairy derivitive. It takes planning but people with celiac usually have no problem in parks. You can bring in snacks if you are on a special diet. I like fritos, lays chips, raisins, corn chips, and ralphs cinnamon rice cakes for snacks.
Do not at home use Rice Dreams as it has gluten. Celiac is the great pretender disease. I get at time malnutrition, bloating so bad I feel like I am having a heart attack, psoriasis like dry skin, hair loss, bad teeth, poor healing, mental unbalance, mood swings, vision problems, phantom pains which are not like real ones, fatigue, nausea, and a rash on my back. I also get a racing pulse from allergens and headaches. The gluten damages the stomach and makes it so the body does not absorb fats, minerals and other nutrients which leads to malnutrition.
