Purchase a Gluten-Free Products List
As with all major grocery stores, much of their inventory is naturally gluten free. This is where a gluten-free products list is a great resource, especially when first adopting a gluten-free lifestyle. While there are many of these lists published in many different forms, the one I like is published by the Denver Celiac Sprue Association and costs $10. The most recent version was published in July, 2009. This version is particularly helpful because most of the regional brands in our stores are the same as those in Denver stores. You can order yours at www.denverceliacs.org/productlist.html
Avoid Bulk Foods
Bulk food items are probably not gluten free because they are easily cross contaminated by other products in the bulk foods section.
Consider purchasing packaged products in larger quantities
Gluten-free packaged foods are relatively expensive when compared to their gluten-filled counterparts. If you like a product, consume it frequently and have room to store multiple packages, consider purchasing the product through amazon.com There you will find a wide selection of gluten-free products sold by the case at unit prices much lower than local grocery stores. However, it may not be a great deal unless you order enough to qualify for free shipping.
