What Is an Allergic Reaction?

An allergic reaction is a response to tissue damage or dysfunction that occurs when an immune-generating body is stimulated again by the same antigen. The response is characterized by rapid onset, strong response, and rapid regression; generally it will not damage tissue cells or cause serious tissue damage, and it has obvious genetic tendencies and individual differences.

Sometimes I see this phenomenon in life: after eating fish, shrimp, crab and other foods, some people will have abdominal pain, diarrhea, vomiting, or itchy skin. Some people inhale pollen or dust. Rhinitis or

Allergies often occur in a relatively fixed group of people because they have

The antigen that induces an allergic reaction is called an allergen. Allergens are a necessary condition for allergies to occur. Allergic

Prevention of allergic reactions is more important than treatment. It should start with paying attention to daily living, proper diet and proper physical exercise. First of all, in the early spring season, the temperature is still cold. Under the stimulation of cold air, the thyroid function is hyperactive, consumes calories, and weakens the body's endurance and resistance. Therefore, the diet is still high in calories. In addition to eating soy products, you can also eat glutinous rice products, soybeans, sesame powder, peanuts, walnuts and other foods. You must also add high-quality protein such as eggs, shrimp, and fish. , Beef and other foods, these foods are rich in amino acids, which can increase the body's cold resistance. In addition, you must ingest enough multivitamins and minerals, such as vitamin D with antiviral ability, foods rich in vitamin D include pakchoi, tomato vegetables, and citrus, lemon and other fruits; while vitamin A can protect and enhance The function of the upper respiratory tract mucosa and respiratory epithelial cells, which can resist the invasion of various pathogenic factors. Foods rich in vitamin A include carrots. Vitamin E has the function of improving the body's immune function and enhancing disease resistance. Foods rich in vitamin E include cabbage, cauliflower, and sesame. In addition, black fungus and mushrooms are also indispensable food. There is also the need to have appropriate outdoor activities to improve the body's disease resistance, which is of great benefit in preventing spring allergies.
