Almost any food can trigger allergic symptoms, including various foods that humans most commonly eat, such as rice, wheat, milk, eggs, and potatoes. It is currently known that there are thousands of foods that can cause allergic symptoms. In our country, common allergenic foods mainly include the following:
Dairy products and milk products: Milk is the most common food that triggers allergies in infants and young children. Milk contains components such as alpha-lactalbumin, beta-lactoglobulin, and casein. Among these, alpha-lactalbumin is the most allergenic component in all milk ingredients. This protein is not heat-resistant, and its sensitizing ability can be significantly weakened after high-temperature processing. However, for patients with severe milk allergies, it can still trigger relatively serious symptoms.
Poultry eggs: Chicken eggs, quail eggs, and egg products can cause allergies in patients of all ages. Among them, ovalbumin in the egg white is the main component that triggers allergies. The allergenicity of ovalbumin is relatively poor in heat resistance. After high-temperature treatment, the probability of triggering allergies from poultry eggs can be significantly reduced.
Seafood and aquatic products: Including fish, shrimp, crab, squid, shellfish, and clams can all trigger allergic symptoms. Especially, stale seafood often triggers allergies even when cooked.
Soybeans and soy products, peanuts, sesame seeds, kidney beans, etc.: This is mainly related to these oil crops containing high levels of protein and glycoproteins. Other legumes such as mung beans, red beans, and green beans, as well as various kidney beans, can also trigger allergic symptoms.
Certain grains: Such as wheat, corn, buckwheat, and cereals. Mites in flour are also an important cause of allergies. The allergens in rice are usually heat-resistant, so popcorn can also trigger allergies.
Nuts: For example, the kernels of nuts such as walnuts, pistachios, cashews, almonds, hazelnuts, pine nuts, and chestnuts often cause allergies. The allergenicity of nuts is relatively strong and can trigger severe allergic symptoms.
Fruits: The allergenicity of fruits is relatively low, but because most fruits are eaten raw, they are also easy to trigger allergic symptoms. Especially the seeds and peels of fruits are more likely to trigger allergies.
Certain meats and their products: Including various mammals (such as beef, lamb, and pork) and various poultry (such as chickens, ducks, geese, and quails). These meats and their products may all trigger allergies, especially spoiled meat which is prone to trigger asthmatic symptoms.
Certain vegetables: Common vegetables include crown daisy, coriander, lamb's quarters, mushrooms, tomatoes, kidney beans, potatoes, carrots, and celery.
Foods with special aromas: Such as green onions, garlic, chili, onions, ginger, seasonings (pepper powder, mustard oil, five-spice powder, curry powder, cumin powder, etc.), and alcoholic beverages.
Other foods and food additives: Coffee, chocolate, beer, fruit wine, white liquor; health products made from pollen and some edible insects (such as silkworm pupae, locusts, cicadas, bean worms, and snails) can trigger varying degrees of allergic symptoms. Food additives such as monosodium glutamate, sweeteners, preservatives, and antioxidants can also trigger allergies.
