peanut allergy information from trusted sources:
Peanut allergy is common and often appears in the first years of life. While many children outgrow allergies to other foods such as milk or eggs, most kids don't outgrow peanut allergy as they get older.
Food allergy is an abnormal response to a food triggered by your body's immune system. Allergic reactions to food can sometimes cause serious illness and death. Tree nuts and peanuts are the leading causes of deadly allergic reactions called anaphylaxis. In adults, the foods that most often trigger allergic reactions include
For someone with a food allergy, eating or swallowing even a tiny amount of a particular food can cause symptoms such as skin rash, nausea, vomiting, cramping, and diarrhea. Because the body is reacting to something that is otherwise harmless, this type of allergic reaction is often called a hypersensitivity reaction. Rarely, a severe allergic reaction can cause a life-threatening set of symptoms called anaphylaxis, or anaphylactic shock. Although about 25% of people believe they have a food allergy, only about 2.5% of adults and about 6-8% of children, mainly younger than 6 years, have true food allergies. The rest have what is known as food intolerancean undesirable reaction to a food that does not involve the immune system.
A food allergy is a rapid and serious response to a certain food. If you have a food allergy, the antibodies in your immune system (the body's defence system) mistake a food for an ‘invader' and attack it. The antibodies normally involved in food allergies are called immune system antibodies (IgE). These release inflammatory substances into your body, causing unpleasant side effects.
The immune system is the body's way to protect itself from substances that it identifies as not its own. The immune system reacts to things that may cause disease, and fights them off. A food allergy happens when your immune system responds after you eat certain foods. Your body makes a mistake and thinks that a certain food is harmful. These foods may not bother other people.
