What is a Food Allergy?

Food Allergy is a life threatening medical condition. It occurs when your immune system quickly reacts to a certain kind of food. You can develop an allergy at any time be it a case that you have already had it for years before. Food allergy occurs in around 1 in 20 children and in about 2 in 100 adults. Even a tiny chunk of a food can do its work and develop an allergic reaction. A substance that causes an allergic reaction is termed as an allergen.

In some people, food allergy can cause severe symptoms or sometimes even results in hazardous condition. The symptoms of food allergies are most common in children but it can also develop at any age. It is generally noted that these allergic reactions are often mild, but they can be very serious at certain times.

More than 50 million Americans have an allergy of some kind. You probably know one of those people or are one yourself. Food allergies are estimated to affect 4% – 6% of children and 4% of adults, according to the Centers for Disease Control and Prevention.

Types of Food Allergies

Types of Food Allergy

Food Allergies are categorized into two main types as per the symptoms and time of occurrence.

1. IgE-mediated food allergy

The type of allergy most commonly seen in infants and children are milk, tree, peanuts, eggs, soy, wheat and nuts. It can involve the lungs, skin, mouth, heart, eyes, brain and gut area. It is triggered by the immune system producing an antibody called IgE. Symptoms include:

  1. Skin rash
  2. Hives
  3. Swelling
  4. Shortness of breath
  5. Stomach pain
  6. Vomiting
  7. Wheezing

2. Non-IgE-mediated food allergy

These allergic reactions aren’t caused by immunoglobulin E, but by other cells in the immune system. Other body parts of the body’s immune system basically react to a certain food to cause an allergic reaction. Any individual can have both IgE mediated and non-IgE mediated food allergies. The diagnosis is somewhat difficult as the symptoms may take several hours to develop.

Why there is a rise in Food Allergy in the Past Few Years?

There is no clear information as to why we are seeing a rise in food allergies so rapidly in recent years. A proper research must be required to find an actual cause and few of them are already underway. The proposed explanation that has not been proven yet includes:

  • Delayed introduction of allergenic foods like nuts, eggs, and peanuts.
  • Methods of food processing, like roasted versus boiled peanuts.
  • Development of allergy to food by skin exposure

These areas require additional research studies, several of which are underway.

Treatments for Food Allergies

Food allergies can be treated by natural remedies and medications as well relieve the symptoms in case of an allergic encounter.

First, let’s start with the medications:

  • Antihistamines
  • Adrenaline

1. Antihistamines

These are used to treat mild to moderate allergic reactions caused by any food. It blocks the effect of histamine responsible for the allergy. Antihistamines work differently, so make it a point to consult your doctor before having any dose. Few aren’t suitable for the children so have a careful observation.

2. Adrenaline

These are used to treat severe allergic reactions. This can be provided as an auto-injector in case of emergency. The medication works by narrowing the blood vessels so that it can counteract the low blood pressure and open up the airways to ease up the process of breathing.

3. Avoidance of diet

Dieticians can always be of great help to teach you the interpretation of food labels to discover ingredients that are made from allergic foods for you. Compliance with such avoidance diets can help you relieve the symptoms and worsen the effect.
