Food allergy is an adverse reaction due to a specific immune response
occurring reproducibly upon exposure to certain foods. It occurs minutes
to hours after food consumption.
Immunological mechanisms can be IgE mediated, non-IgE mediated or mixed IgE and non-IgE mediated.
It may be life-threatening and is the most common cause of anaphylaxis in children.
It should be differentiated from food intolerance in which adverse
reactions from exposure to food arise from non-immunological mechanisms.
Supplementation with the probiotic Escherichia coli (E. coli) strains O83:K24:H31 in newborns resulted in effective intestinal colonization, which was associated with a decreased incidence of allergy over a 5-year follow-up period, according to a study presented at the recent International Congress of Immunology meeting (ICI 2016) in Melbourne, Australia.
In addition to the known evils of maternal smoking during pregnancy on the son’s semen quality, prenatal exposure to paternal smoking can also be harmful, according to data from a large Danish National Birth Cohort (DNBC) presented at the ESHRE 2019 Meeting.
