Is it Food Allergy or Food Intolerance?

Updated: Oct 26, 2021

Food Allergy or Food Intolerance?

The term Food Allergy is used to describe those cases in which the food allergies trigger a reaction that occurs almost immediately, usually within one hour. The reaction is obvious and often quite violent, for example developing a swollen lip or tongue after eating peanuts or becoming violently sick after eating shellfish. Such food allergies can never be eaten again. True food allergies are quite rare. They affect only a small percentage of the population and most often develop during childhood.

The term Food Intolerance (sensitivity) on the other hand, affects a great number of people and can develop at any time of life. The symptoms of food sensitivity rarely happen immediately after the food is eaten. In fact, the reaction is usually delayed by many hours or even many days. For example, the cheese eaten on Monday could be the cause of Wednesday’s asthma attack. It is these delayed food sensitivity reactions which make the detection of the culprit food a very difficult task without the help of our expert laboratory sensitivity test.

Food sensitivity begins when the digestive system is no longer able to process foods as they pass down the digestive tract. These undigested foods sour and putrefy within the intestines. Toxic gut bacteria feed off this undigested food. This creates a toxic gut environment. Bloating, Indigestion, gut irritability is the result. Left untreated, these gut toxins begin to seep into the blood stream. There they trigger the immune system into over-response mode (autoimmunity) causing all manner of chronic inflammatory disease.

Our food sensitivity test can detect the immune system’s IgG antibody response to individual foods. This information is used to guide the food elimination diet. A myriad of scientific publications endorse this approach.
