The Basics Each year more than 50 million Americans suffer from a variety of allergic diseases such as;
atopic dermatitis and other eczemas, hives, allergies to venom of stinging insects (honeybees,
wasps, and fire ants), allergic drug reactions and food allergies. According to
National
Institutes of Health, approximately 5 million Americans, (5 to 8% of children and 1 to 2% of adults) have a true food allergy.
Food Allergy vs. Food Intolerance
Food allergy, also called food hypersensitivity,is a reaction of
body’s immune system to
something in a food or an ingredient in a food usually a protein. Food allergens are not broken
down by cooking or
digestive process. As a result, they enter
bloodstream and cause
allergic reactions throughout
body. Food allergies can cause life-threatening reactions.
Other reactions to foods are called food intolerances or food idiosyncrasies. Food intolerance is
an adverse reaction to a food substance or additive that does not involve
immune system.
These reactions are generally localized, temporary, and rarely life threatening. Lactose
intolerance is an example of food intolerance.
Note: It is very important for individuals who have true food allergies to identify them and
prevent allergic reactions to food because these reactions can cause serious illness and, in some
cases, be fatal. Common Symptoms of Food Allergies Symptoms of food allergy differ greatly among individuals. They can also differ in
same
person during different exposures. Allergic reactions to food can vary in severity, time of
onset, and may be affected by when
food was eaten.
Common symptoms may include: skin irritations such as rashes, hives and eczema, and
gastrointestinal symptoms such as nausea, diarrhea and vomiting. Sneezing, runny nose and shortness of breath can also result from food allergy. Some individuals may experience a more severe reaction called anaphylaxis – a rare but
potentially fatal condition which may include swelling of
throat, difficulty breathing,
lowered blood pressure and unconsciousness. Symptoms usually appear rapidly, sometimes within minutes of exposure to
allergen. Seek immediate medical attention – standard emergency treatment often includes an injection of
epinephrine (adrenaline) to open up
airway and blood vessels.
