My boss just gave me that book! It's not just for Crohn's. The recipes are all "healthy", and then there are exchanges for Crohn's, diabetes, and heart disease. There are quite a few recipes marked "not recommended" for Crohn's, considering the author is a fellow Crohnie. She eliminates almost all dairy in the Crohn's exchanges, and limits fats and sugar, but not gluten. However, in the recipe I made yesterday, she recommend that people with diabetes or heart disease substitute a rice noodle for wheat pasta. So there could be work-arounds for some of the recipes. But if you're looking for gluten-free, this isn't it. This also isn't an eating plan like Maker's Diet or SCD. It's a cookbook designed to help a broad range of people make healthy meals.
Like any other recipe book, it's all going to depend on what you as an individual can tolerate. There are some things that I won't be trying that she lists as Crohn's-appropriate- spinach salad, nuts in some recipes, a couple of broccoli recipes. There are also quite a few recipes using blueberries (not surprising, since she's from Maine) that may not work for some folks. Some things I may adapt further, like limiting or eliminating onions or bell pepper, depending on how active my disease is at the moment. (Two very gassy foods for me.)
And there were some good suggestions that I never would have come up with on my own. Like cutting vegetables against the fiber to make them easier to digest. I've just been cooking the hell out of them and hoping for the best.
So far I've used it just like I would any other cookbook. The recipe is a starting point, and I add or subtract ingredients based on my own preferences, budget, and convenience. And now, what I can tolerate. With this book, I feel like someone's at least skimmed off the most troublesome items, so there's less to work around. The recipes are generally family fare- nothing too exotic, although a few are very New England. I don't remember seeing any ingredients you couldn't find in most neighborhood grocery stores.
If gluten-free is really what you want, you might want to try another cookbook. If you already know a lot about gluten-free cooking, and are willing to adapt recipes as necessary, you might get some ideas from this book.
