Ariana Grande’s Illness Caused by Allergic Reaction to Tomatoes

Ariana Grande had to cancel a couple shows on her Sweetener World Tour.
She wrote on social media, we discovered I had an unfortunate allergic reaction to tomatoes and my throat pretty much closed.
The tour dates for Florida have been rescheduled for November. Concert promoter LiveNaton assures fans they can either receive a refund or hold on to the tickets and they will be honored in November.
She also joked, nothing more unfair than an Italian woman developing an allergy to tomatoes in her mid 20’s
Did you find out later in life you were allergic to something you loved? What was it?
