What is an allergy?
An allergy is a catch-all word for a wide variety of reactions to substances that the body determines to be foreign. Anything that it does not recognize as itself can be considered an allergen. When the body encounters a foreign substance, it reacts by making antibodies or releasing certain chemicals called histamines. When histamines and other substances are released into the system, they cause an inflammatory reaction we call an allergy.

When the body encounters a foreign substance, it reacts by making antibodies or releasing certain chemicals called histamines. When histamines and other substances are released into the system, they cause an inflammatory reaction we call an allergy.
What are the symptoms?
The inflammatory reaction affects the tissue and organs, mainly the skin, mucous membranes, lungs and gastrointestinal tract.
Symptoms commonly produced include itching and watery eyes, runny and congested nose and sinuses, sneezing, respiratory symptoms, headache, skin reactions and rapid heart beat. Other symptoms may include fatigue, intestinal gas or pain, abdominal bloating and mood changes.
Primary external factors causing allergies
Natural environmental substances: Mold, spores, pollen from trees, flowers and grasses, dust (actually dust mites), animal hairs and insects are common substances that normally produce upper respiratory symptoms (allergies ) in sensitive individuals. These allergy producing substances may cause itching, redness and fluid (water & mucous) may affect the eyes, throat, nose, sinuses, bronchial tubes, and lungs.
Foods: Any food may be an allergen. The most common are wheat, milk, eggs, com, yeast coffee and chocolate. These may affect most body systems, with the gastrointestinal, nervous, respiratory and skin areas affected the most when allergies occur.
Chemicals: Both environmental chemicals and food additives can cause allergy reactions, such as pesticides, chemical sprays, hydrocarbons, and hundreds of others. Tobacco also contains many allergens.

for children
may be avoiding foods that they don't need to avoid. A recent study published in the Journal of Pediatrics found that majority of foods identified in positive allergy tests were actually safe for the children tested.
The study looked at 125 children with eczema who had positive blood tests and skin prick tests to foods and who were avoiding those foods. After oral food challenges in the doctor's office, researchers found that between 84% and 93% of the foods were safely re-introduced into the children's diets. There were no eczema flares following the challenges or re-introduction of foods.
The easy availability of allergy blood testing may be leading to children being diagnosed with allergies they do not have. The researchers warn that children may be unnecessarily restricting their diets, which may lead to malnutrition and poor growth.
The researchers recommend that any child who has a positive allergy test be referred to an allergy clinic for safe oral food challenges before a food is completely eliminated from their diet.
