Allergy to foreign protein

Everyone has their own protective immune system. When impacted by some foreign objects, these immune systems will play a role of resistance and can devour or destroy them. If the power is not enough, they will be invaded by these foreign objects, which is the common inflammation we see. Some people are allergic to foreign proteins. What exactly is going on with this symptom?

Allergy to foreign proteins

The normal human body has a physiological protective immune response system. When foreign substances (such as foreign proteins in food or air) enter the human body, the human immune system will recognize these proteins that do not belong to the body and regard them as enemies that will harm the body. It will then produce an immune response to neutralize and eliminate them.

Under normal circumstances, this is the body's response to protect itself from harm. However, people with allergies will overreact to certain substances and mistake certain normal and harmless substances that they eat, inhale, or touch as harmful substances, causing the body to overreact and become allergic to foreign proteins.

For that individual, these substances are allergens. This excessive reaction will damage some normal cells, tissues and organs of the body.

Hair-raising foods and foreign proteins

Fascinating foods refer to foods that are rich in nutrition or have irritating properties and are particularly likely to induce certain diseases (especially old illnesses) or aggravate existing diseases. Taboos on irritating foods are of great significance in both dietary health and dietary therapy. Under normal circumstances, irritating foods are also foods. Eating them in moderation will not cause side effects or discomfort to most people. They will only induce illness in people with certain special physical conditions and certain diseases related to them.

One of the main reasons why irritants can easily cause illness or aggravate the condition is because the foreign proteins contained in irritants can cause some allergic people to develop foreign protein allergies.

In addition, irritating foods such as fish, shrimp and crabs contain histamine, which can increase vascular permeability, microvascular dilation, congestion, plasma exudation, edema, hypersecretion of glands and increase of eosinophils, thereby leading to the body's abnormal reaction, that is, allergic reaction, and inducing skin diseases such as erythema, papules, blisters, fever, etc. Wine, onions, garlic, etc. can directly cause dilation of skin capillaries and accelerated blood flow through alcohol or volatile irritants, thereby aggravating or prolonging existing skin diseases.
