True wheat allergies are very rare; it is estimated to effect 0.1%-2.2% of individuals depending on region. [60] The allergy does not commonly persist into adolescence. Gluten-free foods are safer for wheat allergic patients but they still may theoretically contain wheat's other allergenic proteins. [61]
MSG is a safe and versatile seasoning—think of it like salt, with the bonus of making the flavors of a dish more dazzling on the palate. Add MSG to homemade broth for depth of flavor.
Allergy testing can help confirm or rule out allergies and consequently reduce adverse reactions and limit unnecessary avoidance and medications.

Monosodium glutamate (MSG), also known as sodium glutamate, is a sodium salt of glutamic acid.MSG is found naturally in some foods including tomatoes and cheese in this glutamic acid form.
A nomenclature system has been established for antigens (allergens) that cause IgE-mediated atopic allergies in humans. [2] This nomenclature system is defined by a designation that is composed of the first three letters of the genus; a space; the first letter of the species name; a space and an Arabic number.
Type III hypersensitivity, in the Gell and Coombs classification of allergic reactions, occurs when there is accumulation of immune complexes (antigen-antibody complexes) that have not been adequately cleared by innate immune cells, giving rise to an inflammatory response and attraction of leukocytes.
A person receiving a skin allergy test. A microscopic amount of an allergen is introduced to a patient's skin by various means: [1] Skin prick test: pricking the skin with a needle or pin containing a small amount of the allergen. [2] Skin scratch test: a deep dermic scratch is performed with help of the blunt bottom of a lancet. [3]
The RAST is a radioimmunoassay test to detect specific IgE antibodies to suspected or known allergens for the purpose of guiding a diagnosis about allergy. [10] [11] IgE is the antibody associated with Type I allergic response: for example, if a person exhibits a high level of IgE directed against pollen, the test may indicate the person is allergic to pollen (or pollen-like) proteins.
