Some of you may have different allergies. Some have allergies to certain foods, dust allergies, cold allergies, and so on. One of the most common types of allergies is allergic to certain foods. And, one of the foods that most often cause allergies is peanuts. Are any of you allergic to peanuts? Do you know why you can experience peanut allergies?
What causes a person with a peanut allergy?
Allergy is related to your immune system. The normal immune system will fight infection from foreign substances that can harm the body.
Well, in people with peanut allergies, the immune system is wrong in identifying the protein in nuts. The immune system thinks the protein in nuts as a dangerous foreign substance. Thus, the body will cause excessive reactions and release chemicals (such as histamine) into the blood.
Histamine can then affect various tissues in the body, such as skin, eyes, nose, airway, lungs, digestive tract, and blood vessels. Thus, various reactions occur in the body when the body is exposed to peanuts. Yes, direct or indirect contact with peanuts can cause the body to release histamine and cause allergic reactions. This depends on the severity of your allergy.
The body can cause allergic reactions when exposed to nuts through a variety of ways, such as:
- Direct contact, such as eating beans or foods containing nuts. Sometimes, direct skin contact with nuts can trigger allergic reactions.
- Cross contact, such as eating food exposed to nuts during processing.
- Inhaling, allergic reactions can occur when you breathe air containing nuts, such as from peanut flour. Peanut protein that is inhaled and enters your body can cause allergic reactions.
What happens if a person with a peanut allergy eats nuts?
Peanut allergy can occur to anyone, both children and adults. A person with a peanut allergy can show an allergic reaction, even if he eats only a few nuts or foods that contain nuts. These allergic reactions can occur from mild to severe levels, and can even threaten your life, called anaphylaxis.
This allergic reaction arises because the body secretes histamine compounds to fight foreign substances. Some common reactions that can arise are:
- Skin reactions: itching, red spots on the skin, swelling, and rashes
- Reactions to the respiratory tract: runny nose, sneezing, sore throat, coughing, wheezing, difficulty breathing
- Reactions to the digestive system: upset stomach, diarrhea, vomiting, nausea, and stomach cramps
- Itching around the mouth and throat
- Itchy, watery, or swollen eyes
These reactions can appear minutes to hours after you eat nuts. The reactions that arise may vary between individuals. It all depends on your body. In fact, reactions can appear different at different times in the same person.
