Milk and milk products Milk and milk products are the most common foods for infants and young children, and are also the most common food allergens that induce asthma in infants and young children. However, recent studies have confirmed that some antigenic properties of many different species of animal milk foods are similar. For children with cow’s milk allergy, goat’s milk is not a reliable alternative food, especially for children with severe allergy to cow’s milk. Eggs and egg products can cause allergies in patients of all ages, with the highest allergy rate in infants and young children. The egg albumin in egg whites is the main allergenic component that induces allergies, while egg yolks rarely induce allergies. Many studies have confirmed that fish, shrimp, crab, shellfish and mussels can induce respiratory symptoms, for example, trout, frogfish and mackerel, which have reddish flesh, are very likely to induce allergic symptoms. Not fresh seafood can make the incidence of allergies significantly increased. Oil crops such as peanuts, sesame and cotton seeds are mainly related to the high protein content of these foods, which rarely induce allergic symptoms once made into oil products. However, in the clinic can often encounter patients who consume raw peanut rice triggered asthma. 5, wheat, cereals, legumes such as soybeans, green beans, red beans and black beans can induce respiratory allergy symptoms. 6, meat and its meat products Common ones include beef, lamb, pork, chicken, rabbit and duck, etc. Uncommon meats including dog, goose, turtle and bird meat can also induce allergies, such as allergy to bird meat often occurs in patients with bird egg syndrome. In addition, mites in flour and cereals are also a major cause of allergy. Some vegetables include kidney beans, green beans, white lupins, mushrooms, tomatoes, peppers, leeks, coriander, parsnips, garlic, eggplant, cabbage and ferns. 9, other foods Coffee, beer, wine, whiskey, liquor, health products made of pollen, chocolate and certain edible insects (such as bean worms, grasshoppers and silkworm pupae) can induce different degrees of respiratory allergy symptoms. The above includes almost all the foods that can be exposed to in daily life. Among them, the first 3 categories are the most common allergens, and food avoidance is required when allergies are found. More are never realized and noticed by us, so we need to observe and record them in our daily life.
