Is it normal that foods i haven't visited for awhile give me the shits?

I have eaten these foods before while growing up. But now adays when I have revisited or come across new foods, I just have to shit it like immediately. I used to eat Asian food, but the last 3 times i had it after not eating it for awhile, i had the shits. When while eating it, my shits were chill. Recently, organic burgers have been making me shred over the toilet. :/
