In brief: Not Typical

Food allergies are typically an immediate reaction minutes to a half hour after ingestion of concerning food with symptoms ranging anywhere from hives, wheezing, itching, shortness of breath, wheezing, vomiting, or syncope (fainting).
Light headedness could be associated with drop in blood pressure but brain fog is not a typical sign of allergy. Skin testing by allergist will sort things out.
