Your body doesn't "attack Allergies". When you are exposed to something that sets off your allergies, your body is attacking a protein that is called an "allergen". This allergen can be anything, from pollen or ragweed to dust mites or the scent of a perfume. When you are exposed to the allergen, your body's immune system reacts against it as if it were an invading bacteria, setting up an inflammatory response. This is why you get the itchy watery eyes, runny nose, sneezing, dry throat reaction - it's your body's immune reaction.

Auto-immune
Food allergies occur when the immune system mounts an attack on certain proteins in certain foods. The substances in the food that trigger this immune-system response are called allergens. The immune system is a complex network of cells and molecules that help defend the body against foreign substances. When a properly functioning immune system detects a foreign substance, it responds to this threat by producing proteins called antibodies against the invaders. The antibodies will recognize and attack this foreign substance when they next encounter it. This "battle" is what causes the allergy symptoms.
