Symptoms of Food Allergy

Food Allergy

A food allergy is an adverse immune response to a food protein. They are different from other undesirable responses to food, such as food intolerance, pharmacological reactions, and toxin-mediated reactions.

 The most common allergic component of the food is a protein. These kinds of allergies occur when the body's immune system mistakenly identifies a protein as harmful. Some proteins are resistant to digestion and some are not. Those which are not broken down in the digestive process are tagged by the immunoglobulin E (IgE). These tags trick the immune system into thinking that the protein is harmful for the body. Thus the allergic reactions occur. These reactions can vary from mild to severe. Foods that cause allergies include peanuts, tree nuts (Brazils, almonds, cashews, hazelnuts, walnuts and pecans), fish and shellfish, cows' milk, eggs, soya and wheat etc. Non-food protein allergies include latex sensitivity.

Symptoms of Food Allergy

Some common symptoms of food allergy are as follows:-

·         Itchy or swollen lips, mouth, tongue and throat

Causes and symptoms of Allergy

What is allergy?

An allergy refers to an overstated reaction by our immune system in response to bodily contact with certain foreign substances.  These foreign substances are usually considered by the body as harmless.  Allergy-producing substances in the body are called "allergens". Pollens, dust mite, molds, danders, and foods are some of the examples of allergens. These substances are foreign to the body and thus cause allergy. It depends upon individual to individual. Basically, the foreign substance is not acceptable by the body and the immune system reacts by itself to defend. Hence, the allergy reaction is seen in the body.

Causes of allergy

There are two major causes of allergy. One is the host and the other is environmental conditions or factors.

Host- heredity, gender, race, and age are the prime factors under the host category. Heredity being is the most important and major factor behind the allergy.

Environmental conditions- Variations in exposure to infectious diseases during early childhood, environmental pollution, allergen levels, and dietary changes are some of the major factors connected with the cause of allergy.

There are different allergens of food which causes allergy. For example egg allergy, wheat allergy, peanut allergy, allergy by cow’s milk, goat’s milk or sheep etc. Some people are allergic to dairy products and thus can’t even drink milk.

Signs and symptoms of allergy

Allergens such as dust or pollen are airborne particles. There symptoms arise in areas in contact with air, such as eyes, nose and lungs.

Allergic rhinitis, also known as hay fever, causes irritation of the nose, sneezing, and itching and redness of the eyes.

Inhaled allergens can also lead to asthmatic symptoms, caused by narrowing of the airways (bronchoconstriction) and increased production of mucus in the lungs, shortness of breath (dyspnea), coughing and wheezing.

There are many types of allergies and with different signs and symptoms in different people. 

The symptoms differ because the immune system differs from individual to individual. 

Preventive measures in allergy

It can also be done in some cases like cold, sneezing etc. but the allergies which occur by food in that case the food is to be avoided and one should monitor what he/she eats.
