What is a food allergy?

Food allergies occur when the immune system mistakenly attacks a food protein. Ingestion of the offending food may trigger the sudden release of chemicals, including histamine, resulting in symptoms of an allergic reaction. A food allergy is potentially life-threatening. Scientists estimate that approximately 12 million Americans suffer from food allergies, or one in 25. One in 17 children age 3 and under has a food allergy. What are the common symptoms of a reaction? The symptoms may be mild (rashes, hives, itching, swelling, etc.) or severe (trouble breathing, wheezing, loss of consciousness, etc.). Symptoms may include one or more of the following: a tingling sensation in the mouth, swelling of the tongue and the throat, difficulty breathing, hives, vomiting, abdominal cramps, diarrhea, drop in blood pressure, loss of consciousness, and even death. Symptoms typically appear within minutes to two hours after the person has eaten the food to which he or she is allergic. What is the best treatment for food allergy? Strict avoidance of the allergy-causing food is the only way to avoid a reaction. Reading ingredient labels for all foods is the key to avoiding a reaction. If a product doesn’t have a label, individuals with a food allergy should not eat that food. If you have any doubt whether a food is safe, call the manufacturer for more information. Currently, there are no medications that cure food allergies. Strict avoidance is the only way to prevent a reaction. Many people outgrow their food allergies, although peanut, tree nuts, fish, and shellfish are often considered lifelong allergies.

Food Allergy Advice For Pregnant Mothers Or Young Children

·    Exclusive breastfeeding until at least 6 months of age may prevent or at least postpone allergies from developing.

·    Infants with eczema are at high risk of developing allergies. Accordingly, mothers should try to avoid eating the allergic foods while breastfeeding because the food allergens will pass through the breast milk.

·    Only in extreme cases do we recommend mom not breastfeed. In this situation we recommend using a hydrolyzed formula such as Alimentum or Nutramigen. Occasionally even a hydrolyzed formula is too allergenic for the infant and an amino acid based formula such as Neocate or Elecare is necessary.

·    Several recent studies demonstrate that

·    taking acidophilus daily in the last trimester of pregnancy and while breastfeeding decreases the risk of developing allergies. supplementing your infant’s diet with acidophilus also appears to decrease the risk of developing allergies

Specific Food Allergies
