What Is and What Is Not a Food Allergy?

Food allergy (Greek allon = different, strange; ergon= activity) is an exaggerated reaction of the immune system to certain food substances otherwise not harmful for the man. These substances, when triggering an allergy, are called allergens. Practically any food may contain substances that can act as allergens; most of people with a food allergy are allergic to fewer than four foods at a certain time, though (5). Allergic reaction involves production of IgE antibodies and releasing of histamine into affected tissues. It is histamine that causes most symptoms like itchy skin or diarrhea.

Introduction

All human beings have sneezing in common. Whether you are a loud sneezer or try to muffle it, there are times when you just can’t help but sneeze. For some, sneezing can be a real problem, particularly if they suffer from photic sneeze reflex. Whether your sneezes are caused by allergies or some other reason, sneezes can be embarrassing. They always seem to sneak up on you when you least expect them. Let’s take a look at what causes people to sneeze and how you can treat any conditions that may cause sneezing.

What Causes Sneezing?

There are several reasons that people sneeze. Infrequent sneezes are usually the by-product of small particles that get past your nose hair and irritate the sensitive lining of your nose. You may notice a slight burning or tingling right before or after this type of sneeze.

When the particle or particles reach this sensitive area of your nose, histamines are triggered and are released into your system. This is what makes you feel as though you have a burning sensation in your nose. This signals your body that it needs to sneeze to expel the particles that are irritating your nose. You may not believe it, but your nose isn’t the only body part involved in a sneeze. The entire response to an allergen or particle involves your chest, face and throat muscles as well as your lungs.
