A food allergy is an type of immune system reaction that happens quickly after consuming a certain food. Food allergies are not a common thing but can be very severe for people who have them. Children develop food allergies more than adult. Most food allergy problems can simply be regulated by dietary actions.
The food allergies can be caused when your immune system erroneously treats harmless proteins found in certain foods like they are bad for you and releases chemicals which activate an allergic reaction.
The Immune System:
The immune system effectively guards the body by producing specialized proteins which is known as antibodies. Antibodies recognize the threats to your body which include bacteria and viruses; they signal to your immune system to release chemicals killing the danger and also obstructing the spread of infection.
The Common type of food allergy is one kind of antibody which also called as immunoglobulin E (IgE) erroneously aims a certain protein that found in food as a danger to your body.
Histamine can cause most general symptoms that happen during the allergic reaction. For instance, histamine causes tiny blood vessels for expanding and also near skin to enlarge. This can also adversely affect the nerves in the skin, which can lead to the skin itchy feeling. It also enhances the quantity of mucus which is produced in your nose lining, and it can cause local irritation and burning.
In most of the food allergies the release of histamine is restricted to a certain portion of the body. IE: mouth, throat, skin
In anaphylaxis, the immune system goes into overdrive and releases a huge quantity of histamine into your blood.
In children the foods that largely cause allergic reactions are eggs, milk, soy, wheat and peanut.
