i think i'm allergic to carne asada 😳😳😳

i been noticing whenever we have Barbaques at a family's house and they barbaque chicken or carne asada.... I tend to throw up and get nauseous.... also i have diarrhea and want to take a shit after i eat it...What could this mean?????? this has been going on since when i was junior high .... Im now 22 years old.... Could that mean my stomache doesn't like barbaque foods?
