Am I the only person who doesn't have this issue with eating spicy food?
It reminds me of the "hurr durr Taco Bell gives you diarrhea" memes. Like really? Maybe you need to see a doctor?
I personally don't see any connection between spiciness and stomach/bowel issues.
I think it's just like the "obvious" answer ("food was spicy, now my tummy hurts, therefore spiciness makes my tummy hurt"), when in reality, at most people are just experiencing a correlation.
