Clinical studies have shown that the occurrence of some diseases is related to the intake of some foods, which are not eaten and the disease will not be cured, a phenomenon known as “food intolerance”. Food intolerance is a complex metabolic disease, which is commonly referred to as a chronic disease in which the human immune system treats one or more foods that enter the body as harmful antigens and produces an excessive protective immune response against these antigens, causing abnormalities in various systems throughout the body. Food allergy is associated with immunoglobulin E, and food intolerance is associated with immunoglobulin G. Most patients with food intolerance present with gastrointestinal symptoms and skin reactions, but different individuals may present with very different symptoms for the same food intolerance. There are currently 14 and 90 common tests for food intolerance. The test results can be graded according to the concentration of specific IgG antibodies obtained by the test, and are interpreted as “negative, mild intolerance, moderate intolerance, and severe intolerance”. Grade 0 is negative; Grade +1 is mildly sensitive; Grade +2 is moderately sensitive; Grade +3 is highly sensitive. This combination is the result of a large number of clinical epidemiological statistics. The test requires only 1 ml of blood to be drawn. You can eat and drink normally before the blood draw, no special requirements are needed. 14 items: beef, cod, corn, mushrooms, milk, pork, rice, shrimp, soybeans, tomatoes, wheat, crab. 90 items: food groups: barley, buckwheat, corn, millet, oats, rye, rice; fruits: apples, bananas, and honeydew, grapefruit, lemons, olives, oranges, peaches, pineapples, strawberries, grapes, cinnamon, lingonberries meat and eggs: beef, chicken, pork, turkey vegetables: copra, cabbage, carrots, cucumbers, eggplant, cauliflower, celery, peas, green peppers, garlic, red peppers, spherical Lettuce, mustard seeds, onions, parsley, mixed peas, potatoes, mushrooms, safflower seeds, spinach, squash, sweet potatoes, tomatoes, dairy products: butter, cheddar cheese, milk, goat’s milk, Swiss cheese, yogurt, American cheese Condiments: cane sugar, honey, black tea, tobacco Nuts: cashews, lima beans, peanuts, sesame seeds, soybeans, green beans, sunflower seeds, black walnuts, almonds Seafood: clams Cod, crab, halibut, lobster, oyster, salmon, sardines, scallops, shrimp, fish, trout, tuna Chocolate: chocolate, coffee, cola beans Yeast: brewer’s yeast, baker’s yeast Charges are not quite the same everywhere, about 14 kinds of about 500 yuan, 90 kinds of about 4800-5400 yuan ranging.
