Congress must declare corn an official allergen before corn/corn derivatives are subject to FDA labeling guidelines. Since there is an emerging corn allergy crisis, with potentially life-threatening consequences; I am devoting this blog to advocate for the corn allergy community, and to provide resources to help them navigate this difficult journey. Please join me in demanding that Congress declare corn an official allergen. Thank you! @CornAllergy911

Published Corn Allergy Studies/Statistics
"Maize food allergy: a double-blind
placebo-controlled study."Journal of the British Society for Allergy
and Clinical Immunology, 38:12 2008 Dec pg 1943-9:
"The number of
studies that address IgE mediated maize allergy is all too few."
"Maize is a cause of
IgE-mediated allergic reactions to foods in adults and children. Nearly half of
the subjects recruited were confirmed by challenge to be allergic to maize.
Twenty-three percent of the positive challenge patients manifested symptoms that
involved two organ systems, thus fulfilling the criteria for maize induced
anaphylaxis. Maize is allergenic and can pose a risk for symptomatic food
allergy at a dose of 100 mg."
"Zea m 14, a lipid transfer protein, has
also been isolated from Maize flour. Skin reactivity and IgE antibodies to this
allergen were detected in 19 of 22 patients (86%) with systemic symptoms following
the ingestion of Maize, confirming this as the Maize major allergen . . ."
Maize may moderately often
sensitise or induce symptoms of food allergy in sensitised individuals
(7,15,31,34-37). Allergic symptoms reported have included abdominal pain,
nausea, vomiting, rhinitis, asthma, angioedema, atopic dermatitis, and
"Maize has been
implicated as one of the causative foods of eosinophilic esophagitis, a
disorder with symptoms suggestive of gastroesophageal reflux disease but
unresponsive to conventional reflux therapies (58)."

belonging to the Reduced Soluble Proteins, is a major allergen." Pasini G et al. IgE-mediated allergy to corn: a 50 kDa

RACIAL DIFFERENCES IN FOOD ALLERGY PHENOTYPE AND
HEALTH CARE UTILIZATION AMONG US CHILDREN, Published online: November 22, 2016, American Academy of Allergy
Asthma & Immunology (AAAAI)
"In a study published
in The Journal of Allergy and Clinical Immunology: In Practice, Mahdavinia and
colleagues conducted a large, retrospective cohort study of children ages 0 to
17 years with food allergy seen in Allergy/Immunology clinics at two urban
tertiary care centers in the US. The objective of this study was to characterize
disease phenotypes and disparities in healthcare utilization among
African-American (AA), Hispanic, and White children with food allergy.
“The cohort of 817
children was composed of 35% AA, 12% Hispanic, and 53% non-Hispanic Whites.
Compared with non-Hispanic White children, AA children had significantly higher
rates of having asthma and eczema, and significantly higher rates of allergy to
wheat, soy, corn (emphasis added), fish
and shellfish. Hispanic children had significantly higher rates of allergy to corn (emphasis added), fish and shellfish,
and higher rates of having eczema, but similar rate of asthma. There was a
significant difference in insurance type by race/ethnicity with 55%, 18%, and
11% of AA, Hispanic, and White children covered by Medicaid, respectively.
Compared with Whites, AA and Hispanic children had shorter duration of follow
up for FA with allergy specialist and higher rates of FA-related anaphylaxis
and ER visits."
