In simple terms, wheat allergy should only require the avoidance of wheat and wheat containing products. However, the possibility of cross-reaction with other cereals and plants must be considered, particularly in the management of an IgE-medicated allergy.
In 2004, the Food Allergen Labelling and Consumer Protection Act (FALCPA) was passed by Congress. FALCPA was an amendment to the Federal Food, Drug, and Cosmetic Act which requires that all major food allergens be listed on a food label. FALCPA identified wheat as one of the eight major food allergens. A study conducted by the FDA in 1999 before the allergen labeling act found that 25% of foods sampled did not indicate the presence of peanuts or eggs in the ingredient list, even though the food contained them. FALCPA was passed by Congress so individuals with food allergies could identify safe foods from reading the ingredients on a label. Looking for a gluten-free labeled product would also ensure that the product was wheat free.

Additionally plain potatoes, legumes, many dairy products, meat, fish, poultry, eggs, oils, fruit and vegetables are naturally gluten-free. A healthy balance diet can be created using these naturally gluten-free foods.
There is also a wide range of commercially prepared gluten-free products including mixes, bread, pasta, cookies, crackers, cereals, etc. These manufactured products can be identified by the "gluten-free" designation on the packaging. The notation of gluten-free by US or Canadian regulations ensures that the product does not contain more than 20 ppm gluten threshold.
A referral to a dietitian is crucial to ensure that the diet remains balanced and healthy while avoiding wheat in appropriate levels.
A wheat-free diet may seem daunting at first, but with expert guidance and practical tips the individual with a wheat allergy can live a full and delicious life.
