Allergies Vs Sensitivities

True food allergies are based on exposure to a specific protein component of a food. The immune system incorrectly perceives the protein as a threat and produces antibodies in response. With repeated exposure, cells release histamine and other biochemicals in response to the allergenic food. It is these chemicals that cause the allergy relief symptoms. True food allergies are estimated to affect less than 2 percent of adults and 4 to 8 percent of young children and infants.

Food sensitivities are much more common, although estimates vary. Sensitivities are abnormal reactions to food or food components that do not involve the immune system, but involve the body as a whole. There are three types of food sensitivities:

  • A metabolic food disorder occurs when a person is genetically unable to properly or fully metabolize a food component. This includes lactose intolerance (inability to metabolize lactose), which is different from dairy allergies. A dairy allergy relief can be treated successfully with AAE whereas a true lactose intolerance cannot be treated. However, it is common for people with reactions to dairy to be misdiagnosed as lactose intolerant when the condition is actually a sensitivity.

    Another example of a metabolic food disorder is favism (genetic deficiency causing a sensitivity to a chemical in fava beans.
  • Food idiosyncrasy is another form of sensitivity with an abnormal response to a food or food component, but the mechanism for the response is unknown. The symptoms can resemble those of an allergy relief and can be either severe or mild. Sulfite-induced asthma is one example and causes asthmatic reactions in 1.7 percent of all asthmatics.
  • An anaphylactoid response is a type of reaction that elicits the same release of histamine as a true food allergy relief, but it does not involve the immune system. The specific substance that causes this reaction has not yet been identified. The response is not the same as anaphylaxis.
