What is the most serious food allergy to have

What are the most common food allergies?

Food allergies are overreactions of the immune system against certain ingredients of a food. When consuming products that contain such allergens, those affected can experience allergic reactions such as runny nose, asthma, skin reactions, abdominal pain, vomiting or diarrhea. The most severe form of allergic reaction is anaphylactic shock. Several organs such as the skin, respiratory tract, gastrointestinal system and the cardiovascular system can be affected at the same time. It is then a medical emergency that must be treated immediately, otherwise it can be life-threatening. The most common food allergies are listed here:

• Cow's milk: People who are allergic to cow's milk usually react to the allergens casein and beta-lactoglobulin (a whey protein) contained in milk. Anyone suffering from a cow's milk allergy should completely avoid products containing cow's milk and cow's milk. This also includes foods with additives made from cow's milk protein such as skimmed milk powder, cream or whey, which are contained in many ready-made foods.

• Chicken egg: Allergy sufferers who suffer from this food allergy usually react to the egg whites. Even in processed form as dry eggs, liquid eggs or lecithin, eggs in foods can cause allergies. However, some people with a chicken egg allergy can tolerate baked eggs without any major problems. An impact assessment should always be carried out in consultation with a specialist.

• Nuts and peanuts: An allergy to hazelnuts often occurs as a so-called cross allergy in birch pollen allergy sufferers. Peanut allergies, on the other hand, often manifest themselves as a cross allergy with sensitivities to grass pollen. A nut allergy often manifests itself through skin reactions such as itching, scratchy throat or shortness of breath. A peanut allergy is particularly dangerous where even the smallest amounts are sufficient to cause the most severe allergic reactions. Even traces of nuts and peanuts in finished products or chocolate can be dangerous for allergy sufferers.

• Spices and herbs: Spices such as celery, coriander, basil and curry spices can act as aggressive allergens. A food allergy to celery often occurs as a cross allergy to birch pollen, vegetables or herbs such as mugwort.

• Apples and fruit: Food allergies to fruit are also often cross-allergies. Anyone who experiences problems in the mouth and throat after eating stone fruit is often allergic to birch pollen. On the other hand, allergy sufferers usually react less severely to cooked, baked or otherwise processed fruit. Not only apples, cherries or plums can have an allergic effect, food allergies are also common to types of fruit such as mangoes, lychees or kiwis.
