All about Food allergy

By | March 25, 2010

A food allergy is an immunological response to a food protein. An estimated 12 million Americans have food allergies of one type or another and the prevalence is apparently rising.  More than six percent of children under the age of three and four percent of adults have food allergies.

The general food allergies in adults are peanuts, shellfish, tree nuts, fish, and eggs, and the most common food allergies present in children are milk, eggs, peanuts, and tree nuts.

At this time there is no cure for food allergies. Treatment consists of prevention of diets, in which the allergic person avoids all forms of the food to which they are allergic. For people who are very sensitive, this may involve the total avoidance of any disclosure with the allergen, including touching or inhaling the difficult food as well as touching any surfaces that may have come into contact with it. Food allergy is different from food intolerance, which is not caused by an immune reaction. Try to keep away from the food which cause for food allergies.

Signs and symptoms of food allergies:

  • Anaphylaxis: a severe, whole-body allergic reaction that can result in death
  • Angioedema: swelling, especially of the eyelids, face, lips, and tongue
  • Eczema
  • Hives
  • Itching of the mouth, throat, eyes, skin, or any area
  • Nausea, vomiting, diarrhea, stomach cramps, or abdominal pain
  • Runny nose or nasal congestion
  • Wheezing, scratchy throat, shortness of breath, or difficulty swallowing
  • Mood swings, depression
