Food is certainly no direct threat to the organism. In contrast, it is necessary for a sufficient supply of energy, nutrients and micronutrients, to allow normal functions of a living cell or the organism. The human organism has developed a high degree of tolerance to food and particularly to food proteins - if they enter the organism in the manner intended, through an intact gut barrier.
IgE Allergic reactions usually happen within a few minutes or a few hours after being exposed to the substance or food that you are allergic to. The symptoms can show up immediately in several cases- if it is an allergic reaction to dust, pollen or some food when the body's immune system starts the immediate defence mechanism by throwing up the symptoms. The immune system releases a substance called histamine which shows up as these reactions like sneezing, skin rashes, headache, running nose, nausea and so on. In some people the reaction can be immediate and severe; whereas in others it can be delayed and known as delayed Food Allergic Reactions Type III mediated Allergies.
IgE allergic reactions can bring about shortness of breath, palpitations of the heart and the person need medical attention immediately. People who have an IgG Mediated Food intolerance can have difficulty in digesting the food, and as a result symptoms like nausea, headache, bloating, gas can occur which could lead to the development of an ulcer. Therefore, one needs to check for the symptoms to opt for either IgE or IgG mediated Allergies and thus undertake take either IgE or IgG Delayed Food Intolerance Test.
