Can Food Allergy or Food Poisoning Lead to Hair Loss?

Hello doctor

Could food poisoning or food allergy cause hair loss , and if so permanent or temporary ?

Thank you

I would doubt that there is a connection, but some do believe that food allergy can lead to alopecia areata. I haven’t read anything about food poisoning causing hair loss, but I’d expect that if you had a bout of food poisoning followed by hair loss, it was stress induced (in which case it should be temporary).
