Having a food allergy brings with it the knowledge of how critical it is to avoid the food or foods that one has an allergic reaction to. In just a matter of minutes after consuming a food allergen, a life-endangering reaction can take place. Allergens in foodstuffs are not always obvious, and therefore not always easy to avoid. Enjoying the benefits of allergy free foods means knowing for certain that there will be no surprises in the foods 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.

Approximately 90 percent of all food allergies are caused by eight foods. These are fish, shellfish, wheat, soy, egg, milk, tree nuts and peanuts. Obviously, one can fairly easily avoid some of them, such as shellfish or fish. Others, however, being included as ingredients in other products, are less obvious. Wheat, egg, milk and soy are used widely in many different products. Even foods such as chocolate candy and Asian condiments may include peanuts, a major allergen for many.

In a major step towards protecting consumers, in 2004 the United States passed a law requiring food manufacturers to include allergen information on their product labels, with regard to the eight most common substances. While this was a significant measure, it did not extend to requiring statements by manufacturers regarding the possibility of cross-contamination caused by processing different products on the same equipment.

Cross-contact statements are being including by some manufacturers on their labels voluntarily, but there is still the potential for allergic problems to be incurred when buying food items manufactured for the general population of consumers. It may take only a very small amount of an allergen to cause serious problems for someone sensitive to it. Foods processed specifically with the needs of the food allergy sufferer in mind will have far less probability of containing unwanted allergens.

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.
