Final answer:
The three common foods from the list of the eight most common food allergens are milk, shellfish, and nuts. A food allergy implies an immune system reaction, which can be severe in some cases.
Step-by-step explanation:
Three foods on the list of the 'eight most common food allergens' are nuts, eggs, and milk. These foods are known to cause allergic reactions in some individuals. Food allergies occur when the immune system reacts to these substances as harmful 'foreign invaders'. Symptoms of food allergies can vary but often include vomiting, diarrhea, itching, swelling of the lips and mouth, and trouble breathing. It is important for individuals with food allergies to avoid these foods and seek medical attention if they experience severe reactions.
The eight most common food allergens include milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat. Among these, three foods that commonly cause allergies are milk, shellfish, and nuts. A food allergy is a reaction of the immune system to certain proteins found in food, which are perceived as harmful even though they are typically harmless. Symptoms of food allergies can range from mild reactions, such as hives or gastrointestinal discomfort, to severe reactions like anaphylaxis, which requires immediate medical attention.
It's important to note that not all individuals respond the same way to food allergens. Reactions can vary based on the amount of food ingested and an individual's sensitivity. In comparison, food intolerance is a less severe reaction that does not involve the immune system, and symptoms are often dose-related, meaning they are related to the quantity of food consumed.
