There are a number of different natural food allergies that people may have.
An allergic reaction can produce mild symptoms or even cause death in severe cases.
Shell fish, peanuts, and yeast are some of the most common food allergies.
A person who eats or even has contact with an ingredient, they are allergic to can experience a wide range of negative side effects.
Some of those symptoms include the following:

• Hives
• Rash on face, hands or body
• An itchy feeling, which may lead to rash or hives
• Swollen tongue, lips, and in severe allergies the throat could possibly swell closed
• Difficulty breathing, which may induce an asthma attack

If a person has ingested any food they are allergic to it is important they get to a hospital or doctor for treatment.
People with severe life threatening allergies usually carry an Epi-pen for an allergic reaction.
A shellfish allergy is very dangerous, and people may not realize they are even being exposed to shellfish.
For mild reactions a dose of Benadryl is helpful in relieving hives and a rash.
A person who is known to have asthma should have an inhaler on hand.
When dining out, it is best to avoid any menu items that could have been cross contaminated unknowingly with a food that can cause a serious allergic reaction.
A menu that has all the ingredients listed is also helpful in determining what is safe to eat.
The dangers of eating anything that has been near a known allergen are just as severe as eating the allergen itself.
It is important that you educate yourself with as much knowledge as possible so you will be prepared if someone you know has an allergic reaction to something while you are out to dinner, or even at a ballgame, or on a plane.
