Abstract
A method for determining the presence of food allergy or food intolerance and their cross-reactive tissue antigens is disclosed. The method includes determining a level of antibodies against a dietary antigen in a mucosal sample from the patient and comparing the level with normal levels of the antibodies. Dietary antigens that were tested include milk and milk products; eggs and egg products; meat and meat products; fish, mollusks, and crustaceans and their products; oils, fats, and their products; grains and grain products; pulses, seed, kernels, nuts, and their products; vegetable and vegetable products; fruit and fruit products; sugar, sugar product, chocolate products, and confectionary; and spices.
Claims21
A method for determining a presence of food allergy or food intolerance to a food in a patient, comprising:
- (a) determining a level of antibodies against a dietary antigen present in the food in a mucosal sample from said patient;
- (b) comparing the level determined in step (a) with normal levels of said antibodies in said mucosal sample, wherein
- (i) lower than normal levels or about normal levels of dietary antigen antibodies indicate optimal conditions;
- (ii) higher than normal levels of dietary antigen antibodies indicate a food allergy or food intolerance to the food.
A method for determining a type of antibody in a presence of allergy or intolerance to a food in a patient, comprising:
- (a) determining a level of antibodies against a dietary antigen present in the food in a first mucosal sample from said patient;
- (b) determining a level of antibodies against cross-reactive tissue antigen present in a second muscosal sample from said patient, wherein said first and second samples are the same or different;
- and
- (c) comparing the level of antibodies determined in steps a) and b) with normal levels of said antibodies, wherein
- (i) about normal levels of antibodies against the dietary antigen and normal levels of antibodies against cross-reactive tissue antigen indicate optimal conditions;
- (ii) higher than normal levels of antibodies against the dietary antigen and about normal levels of antibodies against cross-reactive tissue antigen indicate food allergy and intolerance without cross-reacting to tissue antigens;
- (iii) about normal levels of antibodies against the dietary antigen and higher than normal levels of antibodies against cross-reactive tissue antigen indicate an autoimmune reaction not related to the dietary antigens;
- and
- (iv) higher than normal levels of antibodies against the dietary antigen and higher than normal levels of antibodies against cross-reactive tissue antigen indicate a presence of food allergy and intolerance resulting in an autoimmune reaction.
