Although people with celiac disease need to avoid many common grains such as wheat, a wide variety of grains are safe for people who require a gluten-free diet. In this Health Alert, Johns Hopkins reviews safe grains and food ingredients for people with celiac.
A diagnosis of celiac disease -- intolerance to the protein gluten -- means that patients must avoid all foods that contain gluten, including all products made with wheat, barley, rye, and related grains. A diet without these common ingredients may seem restrictive at first, yet there are many alternative grains, such as teff (a cereal grain native to northeastern Africa), that do not have any naturally occurring gluten and can be used safely as gluten substitutes.
Below is a list of acceptable and unacceptable grains and food ingredients for people who eat a gluten-free diet. However, there are some caveats. The first deals with oats: Recent research suggests that pure oats do not contain gluten and appear to be safe for people with celiac disease, but obtaining oats that have not been contaminated with gluten during the food-manufacturing process is difficult. Therefore, experts currently recommend that people with celiac disease avoid oats and all derivatives of oats, including oat bran, oat fiber, and oat gum.
The second caveat deals with alcohol: Although many spirits such as gin, vodka, and whiskey are made with grains that contain gluten, research has demonstrated that gluten doesn't survive the distilling process and is undetectable in the final product. Because of this finding, the Canadian Celiac Association and the Celiac Disease Foundation in the United States say that such spirits are acceptable for people with celiac disease.
Ask your doctor or dietitian if it's safe for you to drink gin, vodka, and whiskey. Also, check that a product's label says "gluten free" or verify with the manufacturer that a product is gluten free before consuming it. Many otherwise gluten-free products come into contact with gluten during processing, causing contamination. Last, check with the product's manufacturer regarding the following ingredients to ensure that their sources do not contain gluten: caramel, hydrolyzed plant protein (HPP), hydrolyzed vegetable protein (HVP), malt and its derivatives, modified food starch, monosodium glutamate (MSG), and textured vegetable protein (TVP).
