Frankel shared more details about her allergy, saying she is sensitive to fish in both physical and airborne forms, such as fumes from cooking.
"To clarify: some allergens are transmitted by touch & air. Fish is one & is fatal. The more exposure to them, the more susceptible. It's not like an immunity thing where more exposure means less susceptible. It's opposite. I've always kept it quiet but that's over now."
