Allergy and Sensitivities
Adverse reactions to foods, chemicals, or environmental pollutants are causing major health problems.Americans often report that they must avoid specific foods or chemicals because of unpleasant physiological reactions. Such reactions may include
These reactions can be caused by over-stressed and hypersensitive immune systems. This is believed to begin at the intestines.Foreign bodies in the form of food proteins enter through damaged intestinal walls and these foreign proteins (antigens) trigger the immune system to form antibodies. These hypersensitive immune responses include
| Type I | Type II | Type III | Type IV | |
|---|---|---|---|---|
| Allergy Response | IgE mediated, TH 2 promoted | IgG and complement mediated, Cytotoxic, TH1 promoted | IgG Immune complex mediated, TH1 promoted | Cell mediated, TH1 promoted |
| Timeline | Immediate onset of symptoms | Delayed hypersensitivity reaction which takes 2-3 days to develop | ||
| Immune Response | Immune complex mediated, Involves the deposition of antigen/antibody complex mainly in the vascular walls, pleura, pericardium, synovium, and glomeruli | Not antibody mediated It is a cell mediated response | ||
| Symptoms or Manifestations | Anaphylactic reaction such as hives, food allergies, eczema, debilitating migraines, swelling of the mouth, vomiting, difficulty breathing, or anaphylactic shock. | Blood transfusion reactions, autoimmune hemolytic anemia. | -Allergic contact dermatitis to poison ivy, oak, sumac-Hand dermatitis from contact with chemical or latex, etc. |
For food reactions, most conventional physicians only believe in the Type l reactions. Consequently, the same goes for insurance coverage. While only 5% of the population is affected by this Type l reaction, it is estimated that more than 40% of the population that have more delayed reactions (including theType ll and Type lll reactions). Thismeans the production of antibodies occurs hours or days after the food is consumed. The delay in symptoms, a food sensitivity, makes it difficult to determine which foods may be the trigger.
Some reactions to food do not include an IgG or IGE mediated immune response, they are referred to as food intolerances. These can arise from chemicals or additives in food with MSG. preservatives, or food coloring, but are most often due to enzyme deficiencies. A common example would be lactose intolerance in individuals who lack the enzyme lactase and cannot digest lactose milk sugar, leading to bloating and diarrhea upon eating dairy products.
At DNA Associates, Dr. Faria believes that allergy testing should evaluate all Type l, Type ll, Type lll, and Type lV reactions.
Food allergies and intolerances can manifest many of the following symptoms:
If you would like guidance in looking for the root cause of chronic symptoms or illnesses, Dr. Faria isaphysician to consider. She has researched food cross reactions extensively, which means she will thoroughly explain these cross reactions when she reviews the diet diary in addition to the suggested tests above.
At DNA Associates, we also provide other healing modalities
Healing is a journey, for some it may take 1-2 months, for others it may take moreto bring harmony back to the immune system and reduce unpleasant symptoms.
