Patient: My child is always allergic, sometimes he gets allergic when he doesn’t pay attention to food, and he gets a rash on his body, and sometimes he can’t even change his environment. Is there any way to improve allergies?
1.What is allergy?
Generally, people who are prone to allergic reactions and allergic diseases and cannot find the cause are called “allergic”. People with “allergies” can have different allergic reactions and allergic diseases, such as eczema, urticaria, allergic asthma, some are particularly sensitive to certain drugs, drug dermatitis, and even exfoliative dermatitis. But the occasional high reactivity to a known factor can not be called “allergic”.
2.What are the causes of allergies?
The causes of “allergies” are complex and varied, probably because children’s skin is delicate and can be caused by wind or sun exposure. Therefore, it is important to avoid these factors. In addition, pay attention to whether the child eats mother’s milk or not. If the mother’s diet is not careful, eating fish and shrimp can cause allergy in children through breast milk. This requires adults to pay attention to the diet and avoid allergy-prone foods, such as: fish and shrimp, mushrooms, strawberries, etc.
3.What are the characteristics of allergic body?
From an immunological point of view, people with “allergies” often have the following characteristics.
(1) Immunoglobulin E (IgE) is an antibody that mediates allergic reactions. The amount of IgE in the serum of normal people is very small, but the serum IgE of some “allergic” people is 1.000 to 10.000 times higher than normal.
In normal people, there is a certain ratio of helper T-cell 1 (Th1) and helper T-cell 2 (Th2) cells, which are coordinated to keep the body’s immunity in balance. Th2 cells secrete a substance called interleukin-4 (IL-4), which induces the synthesis of IgE and raises serum IgE levels.
(3) Normal human gastrointestinal tract has a variety of digestive enzymes, so that the protein food entering the gastrointestinal tract is completely decomposed and then absorbed into the blood, while some “allergic” patients lack digestive enzymes, so that the protein is not fully decomposed and absorbed into the blood, so that foreign proteins enter the body and cause gastrointestinal allergic reactions. These patients often lack the protective antibodies – secretory immunoglobulin A (sIgA), which are distributed on the surface of the intestinal mucosa, and the lack of such antibodies can cause inflammation of intestinal bacteria on the mucosal surface, which accelerates the absorption of foreign proteins by the intestinal mucosa and induces gastrointestinal allergic reactions.
④ Normal human body contains a certain amount of histamine enzyme, which has a destructive effect on histamine (which can cause smooth muscle contraction, capillary dilation, increased permeability, etc.) released by certain cells in allergic reactions. Therefore, even if normal people have allergic reactions to certain substances, the symptoms are not obvious, but some “allergic” people lack histamine enzymes and cannot destroy the histamine that triggers allergic reactions, and show obvious allergic symptoms.
The root cause of these immunological abnormalities is often closely related to genetics.
4.What should allergic patients pay attention to?
What should I do if I have allergies? The most important thing is to avoid contact with allergy-causing substances as much as possible, because one more contact will result in more immune substances in the body against the allergens, and the reaction will be more intense; on the contrary, if there is no contact with allergic substances for a long time, the corresponding antibodies or lymphocytes will gradually decrease, and the allergic reaction will gradually disappear on its own.
For frequent allergic reactions, parents had better record the contents of their children’s day, such as what foods they have eaten, where they have been, what smells they have smelled, what special things they have touched, etc., in the hope of finding possible allergens, avoiding future contact with them, and preventing the occurrence of allergic phenomena. In addition, you should also take your child to the hospital and take anti-allergy medication appropriately under the guidance of the doctor.
5.How to improve allergy?
①Desensitization therapy
Desensitization therapy is used for certain patients with severe symptoms and can help change the allergic constitution. In this therapy, the doctor chemically alters the patient’s serum to make it dilute. An antigen dip made of altered allergens and substances such as milk and pollen is injected subcutaneously and the concentration of allergens is gradually increased to adjust the body’s immune system so that the allergic person’s body develops resistance to allergic substances, thus effectively preventing allergy.
②Dietary regulation method
Allergic patients should pay attention to a balanced diet and consume less greasy, sweet and stimulating foods, tobacco and alcohol. Some foods are also allergens, so pay attention to identify them. Eating vitamin-rich foods can strengthen the body’s immune system. According to nutritionist research, onions and garlic contain anti-inflammatory compounds that can prevent the onset of allergies. There are also a variety of vegetables and fruits that can fight allergies, with broccoli and citrus being particularly effective. Allergic people should drink soy milk every day.
Dietary principles
Avoid foods that cause allergies, eat a regular diet, choose foods high in protein and calcium, and have enough calories, and forbid cold foods.
According to a survey conducted by Japanese experts, in addition to genetic factors, food can also trigger an allergic attack. Meat, milk, eggs and other animal foods are the main culprits.
Meat, for example, can reduce the quality and size of red blood cells in the body. Such red blood cells lack vitality and are prone to rupture. The human body composed of such low quality red blood cells, the ability to adapt to nature and assimilation function is greatly weakened, coupled with the protein molecules of milk and eggs, easily penetrate from the intestinal wall into the bloodstream, forming histamine, serotonin and other allergic toxins, stimulating the body to produce allergic reactions, causing the peripheral blood vessels to dilate and lead to skin inflammation.
So, is the only way to free allergic people from their dilemma is to discard animal foods from the recipes? Of course not, because animal foods are the main source of many important nutrients that guarantee human development, and complete restriction is neither possible nor necessary.
For this reason, scientists have researched a wonderful strategy: reduce some animal food intake, and eat more brown rice and vegetables, you can make the child’s allergic body improve. The mystery here is that brown rice and vegetables provide red blood cells with strong vitality, and no foreign proteins into the blood stream, so it can prevent atopic dermatitis from occurring. Japanese experts have developed food formulations for this purpose, such as cakes with millet and tares as the main ingredients, wheat flour for children, and “hypoallergenic rice”. The same applies to adults with allergic constitution.
6. Avoid allergenic and irritating foods.
(1) Cold food.
Cold foods tend to stimulate our throat, trachea and gastrointestinal tract, causing blood vessels and muscles to contract due to tension, thus causing some allergic reactions.
(2) Greasy foods.
Many people like to eat fried food and big fish and meat. These greasy foods tend to hinder the digestive ability of the stomach and intestines, but once the stomach and intestines malfunction, this is also a major cause of allergies.
(3) Spicy and stimulating food.
Some spicy and stimulating condiments can emit irritating odors that can easily stimulate the respiratory and esophageal tracts, which are also prone to allergic attacks.
(4) Shrimp, crab and other salty and cold foods.
Some of these foods contain high levels of foreign proteins, which can easily stimulate allergic reactions in the body, so they should be avoided.
On the contrary, foods that are light and rich in vitamins and plant proteins, such as soybeans, brown rice, buckwheat, soy products, chestnuts, carrots, cabbage, green peppers, fruits, low-cholesterol dried fruits, etc., should be consumed more often, and the normal diet should be nutritious in order to improve the body’s immunity, which can also reduce the occurrence of allergy symptoms. This can also reduce the occurrence of allergy symptoms.
③ Correct choice of skin care products
Since the symptoms of allergic skin vary from person to person, their performance also varies. Therefore, the choice of skin care products should be very careful, and the following principles can be followed when purchasing.
1, do not choose products that smell too fragrant, because they contain too many fragrances, too complex, easy to cause allergies.
2, products containing alcohol and fruit acids should also be used with caution, because of its large stimulation of the skin, the sensitive skin undoubtedly added to the problem.
3, do not use deep-cleaning scrubs and exfoliating creams, these are products that aggravate allergies.
4, when buying, should choose the label “for sensitive skin”, or “hypoallergenic”, “tested by dermatologists” and other words of the product.
