If you have a food allergy, you know that it is essential to avoid the allergen that you have a reaction to. You also know how quickly adverse reactions can occur, and how serious they may become. No matter how careful you are, allergens can be found in products where you least expect them. One of the benefits of allergy free foods is knowing precisely what you are getting in the products you eat.

Estimates are that around 2 percent of adults and from 4 to 8 percent of babies and children are sensitive to one or more food allergens. In recent years it seems that these numbers are increasing for young people. Visits to emergency rooms for severe food allergic reactions number around 30,000 each year for Americans. From these figures, it seems obvious that the more closely one can control the quality of one’s food with regards to allergens, the better.

It often takes only a few minutes, and almost always less than an hour, for an adverse reaction to a food allergen to occur. The reaction may be minor, such as an itching of the mouth or on other parts of the body, or severe enough to cause death if not treated immediately, as in anaphylactic shock. There is no way to cure food allergies, though children, and sometimes adults, do outgrow them with time.

There are eight substances that are responsible for ninety percent of all food allergic reactions. They are milk, egg, peanuts, tree nuts, fish, shellfish, soy and wheat. Some foods, such as fish or shellfish, may be easier to avoid than others which are used as ingredients in other foods. Milk, egg, soy and wheat are extensively found in a variety of processed foods. Peanuts are also used in many other foods, such as Asian sauces and candy, and can cause a severe reaction in those sensitive to them.

An important United States law was passed in 2004, known as FALCPA. This act required food companies to clearly state on their labels if the product includes any of the 8 major allergy-causing substances. However, the law did not require the manufacturers to include information regarding possible cross-contamination of foods processed by equipment used for several different types of foods, perhaps including known allergens.

While some food manufacturers do include such cross-contact information on their labels, there may still be risk associated with buying foods produced for the general population. Sometimes only a minute amount of a food allergen is needed for someone to have a severe reaction to it. Foods produced specifically for food allergy sufferers have a greater probability of being safe to consume.

When in doubt about the safety of a particular food with regard to allergens, one can contact the manufacturer with questions concerning ingredients or cross-contamination. Foods produced by companies focused on allergen-free products may provide a higher degree of assurance that their foods are safe. One of the benefits of allergy free foods is, along with physical safety, greater peace of mind in knowing that you and your family are at lower risk for food allergic reactions.
