Everyone knows that disease comes from the mouth, especially skin allergies are more afraid of a high protein diet, our ancient Chinese medicine, etc. had a hairy thing to say. Therefore, during our consultations, many patients often ask what they should or should not eat instead. In fact, many diseases are a misunderstanding, not necessarily food allergies, but more often problems with our gastrointestinal tract, resulting in poor digestion or absorption of certain toxins that cause disease after the food has entered. Generally speaking, the gastrointestinal flora environment or the skin flora environment of people born vaginally is similar to the mother’s vaginal flora environment, while the gastrointestinal flora environment and skin flora environment of babies born open is closer to that of the hospital maternity ward, with more harmful bacteria than beneficial bacteria, so the intestinal problems of such children are more obvious, such as premature milk feeding, etc., and they are more prone to allergies than those born open. Such children are more prone to allergies and more severe symptoms than those born under normal conditions. Therefore, it is better to promote breastfeeding for such children, and to postpone the addition of milk and eggs for about a year, so that the intestinal mucosal barrier function is more perfect. In addition, often eat out, it is possible to bring H. pylori into the stomach, causing gastric disease, damage to the gastric mucosa will easily trigger poor gastrointestinal digestion, aggravate the damage to the gastrointestinal mucosa, gastric leak or intestinal leak disease. In addition to stomach discomfort, feeling of fullness, acid reflux, burping, bad breath, abdominal pain and diarrhea, or constipation, or very smelly stools, patients may have many other symptoms, such as headache, itching, etc. Each person has different symptoms, such as skin allergies like eczema, measles, perioral dermatitis, acne, psoriasis, allergic purpura, skin amyloidosis, discoloration or vitiligo, etc. It is best to pay attention to whether there are gastrointestinal or Mucosal infections such as throat, inflammatory disease problems, and early examination and treatment. Because harmful bacteria such as Helicobacter pylori will prevent the diamine oxidase secreted by the mucous membrane of the gastrointestinal tract from degrading putrescine and other substances in the gastrointestinal tract, as a result, a large amount of toxic substances such as histamine enters the blood in excess, triggering skin diseases such as allergies, and at this time, certain inappropriate diets go in, it will stimulate it, causing disease attacks or aggravation. What is still not clear is the intestinal flora environment in the human body, just like the ocean, if the environment is better, beneficial organisms will be generated in abundance, such as the intestinal acidic, lactobacillus, bifidobacteria, enterococci and other beneficial bacteria will increase, they protect the intestinal mucosa, maintain the balance of the local environment, but if the intestinal pH changes, such as alkaline environment, like Candida, mold, corrosive bacteria, etc. will They live on protein, and if people consume too much high protein, they will have a full meal and eliminate all kinds of waste gas, which contains a lot of biogenic amines into the blood, naturally causing itching, causing a variety of discomfort or skin diseases. They also cause damage to the intestinal mucosa, making him porous, and large allergens and other substances are more likely to be inhaled into the blood, leading to the occurrence or aggravation of allergies. Especially nowadays, the emergence of fast food, the accelerated pace of life, fatigue and stress have a huge impact on human immunity, especially intestinal immunity. Once the balance is broken, even a little bit of drinks, brine, alcohol, snacks, certain fruits containing histamine, etc., will stimulate the mast cells on the intestinal mucosa that have been stimulated by harmful bacteria to degranulate, releasing a large amount of histamine into the intestine and blood, triggering allergy symptoms and inflammatory skin diseases. diseases, etc. Many people think I have a good appetite and no diarrhea, there will be no problem, but in fact, when you have a skin disease can not be cured in time, you have to think whether the gastrointestinal tract problems, timely examination, supplement probiotics, adjust the diet structure, skin disease may be reduced or cured not to occur.
