What if I'm allergic to wheat?
Wheat allergies and the need for special diets because of other allergies or health concerns are fairly common. You, or someone in your family, might not be able to consume wheat or many other recommended foods. But remember, wheat is not the only recommended grain. You can have a successful longer-term storage without a drop of wheat. Store those grains that you and your family can eat.
The Church of Jesus Christ of Latter-day Saints recommends that you store "wheat, white rice, corn or other grains." Rolled oats are included on their list of products that can be stored for 30 years. If your family is allergic to wheat, but not gluten, oats are a good choice. Rice is a good grain for almost all food allergies. All of the different grains can be ground to make flour. Other grains may also be appropriate for longer-term storage, but avoid pearled barley and brown rice for longer-term storage (but they would be appropriate for your three-month supply) because they have very short shelf-lives. If you are considering storing a grain that is not already recommended for long-term storage, be sure to find out the recommended shelf life from reputable sources before you buy a lot of a product only to have it go bad quickly.
