There are a several magazines catering to the GF and multiple food intolerance communities. Generally speaking, these are folks who can not cheat. In other words, gluten free or whatever free is not optional,due to several allergy requiring epi-pens, or celiac and other autoimmune conditions or just severe reactions to trace exposure and cross contamination.
Gluten Free Living, Easy Eats (online), GlutenFreeda (online) and Delight. Celiac.com offers a Journal of Gluten Intolerance that adds more research to the mix.
There's often some good general info about travelling, communicating with wait staff and encouragement to improve cooking skills, etc. They can be handy for generating ideas for meals for holidays or special occasions, but almost all of the recipes are high carb, and very concerned with fiber.
I would love to see one of these media outlets do an article on Paleo as a positive choice, rather than "I can't tolerate grains" - a statement that is not uncommon on the gluten boards.
