Hispanic adults are over-represented among those with peanut allergies. They account for 20.9% of those with peanut allergies, but 15.4% of the U.S. population (1). It is unlikely that Hispanics have genetic predispositions to peanut allergies because available data indicate lower prevalence in many Latin American countries compared to the United States. Research carried out in Mexico, for instance, finds lower levels of peanut sensitization compared to the United States (7). There are at least 25 countries included in the United States “Hispanic” taxonomy; the classification masks crater-like chasms in health beliefs, healthcare access, dietary practices, and health outcomes among different sub-populations.
Non-Hispanic Blacks are also over-represented among adults with peanut allergies. They account for 15.5% of those with peanut allergies, but 11.6% of the U.S. population (1). Even though genetically verified African ancestry has been linked to peanut allergies (10), a caveat is that other studies report different sub-populations in a single country with differential risks for peanut allergies (11). If the results for South Africa are replicated across the more than fifty countries on the continent and, then, factored with the genetic inheritance of non-Hispanic Blacks, the story is no longer so straightforward. A compelling argument for there being an environmental role is that many non-Hispanic Blacks are thought to have ancestry in West Africa. In the two largest West African countries by population, Nigeria and Ghana, peanuts are main ingredients in stews and marinades, but severe allergic reactions are rare.
