Yeah!!! "Living Without" is a wonderful publication: "a lifestyle guide to achieving better health," according to its website. It covers news about gluten free food, but addresses other food allergies, sensitivities, and intolerances as well.
As I just downloaded the e-book myself, I haven't made any of the recipes, but I bet they're good! You will have to go through the checkout process on the website even though the book doesn't cost anything. Happy baking! Here's the link:
