Allergic reactions are mainly attributed to genes. They are inherited from family members and passed on from generations to other generations. Certain things cause people to exhibit allergies, such things include;

  • Insect bites
  • Certain medications
  • Certain plants
  • Pet dander
  • Certain foods

More commonly, people show higher allergic reactions for food.

An allergic reaction occurs when cells in the immune system interpret a foreign substance as harmful. The immune system reacts harshly to this foreign substance and produces a chemical called Histamine. This chemical causes allergy symptoms such as inflammation, sneezing and coughing. Some people show mild allergic reactions and this is usually treated with home medication. However, in some cases, people show chronic allergic reactions and such people need treatment from a medical professional.

When trying to avoid allergic reactions, there are certain food that should be avoided. Such foods have been known to cause allergic reactions. For people who have food allergy, exposure to even small amounts of the problem food can trigger an allergic reaction. Symptoms begin to show few minutes after exposure, while in some cases, symptoms start showing after few hours. Symptoms of food allergy include;

  • Swelling of tongue, mouth or face.
  • Difficulty breathing.
  • Low blood pressure
  • Vomiting

Some common everyday food that can cause allergic reactions are;

  1. EGGS

Egg allergy is more common in childhood and about half of the children who have it, outgrow it by the age of 3. In very few cases, egg allergy can cause anaphylaxis. Three proteins have been attributed to causing egg allergy and they are;

  • Ovomucoid
  • Ovalbumin
  • Conalbumin

Cooking may destroy some of these allergens but not in most cases, so some people react to both cooked eggs and raw eggs.

  1. FISH

Fish allergy often leads to severe reactions, including anaphylaxis. Adults are more likely to have fish allergic reaction than children. This may be because adults eat fish more often than children do. People who are allergic to one type of fish often react to other types of fish. This is because, the allergen in this fishes are similar. Cooking does not destroy fish allergens. In rare cases, people with fish allergy can be allergic to cooked fish but not to raw fish.

Most children outgrow milk allergy but one fifth of children who have milk allergy will still be allergic when they become adults. The symptoms of milk allergy are often mild and can affect any part of the body. Milk allergy results in anaphylaxis on rare occasions.
