What are Allergies
An allergy is a hypersensitivity to a foreign substance that is usually harmless but produces a violent reaction in the allergy sufferer. Allergies are generally the body's effort to eliminate something it considers unsuitable

There are different types of allergies.
Some of the most common types are: Nasal allergies, and Chronic Allergies
Nasal allergies refer to the interaction of allergens with cells within the lining of the nose


Chronic Allergies are a bit more serious than nasal allergies.
An individual with chronic allergies may have nasal allergies and will also start to be affected by nonallergic stimuli
These can include dry air, cold air, smoke, and particles in the air

Common allergens include pollens, dust, dust mites, mold spores, and animal dander.

Food Allergens
Twelve of the most frequent food allergens are: milk, caffeinated and decaffeinated drinks (chocolate, coffee, tea, and colas), eggs (http://www.mamashealth.com/egg/eggfreeproducts.asp), cereals (especially corn and wheat), oranges and orange juice, tomatoes (http://www.mamashealth.com/fruit/tomato.asp) and tomato juice, meat (pork, beef, chicken), fish, nuts, vitamin preparations, drugs and food additives.

The following substances are sometimes present in cow's milk may cause human reactions: wheat, peanuts, linseed, cottonseed, ragweed, bacteria, antibiotics, hormones, and other drugs and chemicals. Chronic cough, asthma (http://www.mamashealth.com/asthma.asp), rhinitis, bronchitis (http://www.mamashealth.com/infect/bronchitis.asp), urinary bleeding, constipation (http://www.mamashealth.com/constip.asp), and recurrent pneumonia (http://www.mamashealth.com/infect/pneu.asp) may all be caused from milk allergy

What are the treatments for Nasal Allergies?
The most important step in allergy treatment is avoiding the allergen
This may be possible for people with pet allergies
This technique is less practical for those who are sensitive to pollens and molds. However, if you are sensitive to pollen, you can reduce the number of pollen producing flowers and trees in or near your home
