An allergy is the result of an overreaction by the body’s immune system in the presence of an allergen. However, how does that work, exactly? Knowing how the immune system responds to allergies will help you to understand what is happening when you suffer that runny nose, itchy rash or stomach upset.
Having an allergy to a particular food or group of foods can either be a minor annoyance or a life-threatening matter. The unfortunate issue with childrens food allergies is that they are hardly ever realized until an allergic reaction has occurred. This can be an alarming situation for parents who do not know what is happening when their child eats something that they are unwittingly allergic to.
