DO
YOU KNOW?...
An allergy is an abnormal sensitivity or
reaction of your immune system to a substance (an allergen) that you eat,
inhale or touch. Non-allergic people can usually tolerate this substance.
Nearly 50% of all people who suffer from allergies have hay fever. If both
parents have allergies, their children are more likely to develop an allergy,
although not always the same kind of allergy.
