This is one of the questions I answer in more detail my book, Astoria Mills -Health & Nutrition. Included in the book is a mini-encyclopedia of over 250 foods you can eat, information about nutrition, gluten free baking terms, and ingredients. Plus ingredients to avoid.
With the new Astoria Mills Enriched Gluten Free Mixes -getting more nutrition is now easier. Included in each mix is a proprietary Enrichment Formula especially created to answer many of the specific dietary insufficiencies inherent in some gluten free diets. After all, Brownies, as delicious as they are, we all want good staple breads with added fiber and nutrition.
I know you also want foods that taste great, because as I always say, "If it doesn't taste good, they won't eat it!" If you are gluten intolerant, celiac, or just trying to eat healthier, you need to feel that you are not missing out on great foods.
