Even though most restaurants are using fresh ingredients and more "whole foods," finding gluten-free restaurants or safe options when eating out might take a look more strategy than cooking foods at home or buying certified pre-made options.
Because of the high risk for cross-contamination, not all restaurants are going to be able to handle gluten allergies. And eating out requires you to be your best advocate; by knowing what to look for, what to avoid and how to communicate your dietary needs clearly.
Plan ahead and research restaurants online that offer gluten-free menu options.
