Also if eating Taco Bell is usually causing you diarrhea you have some underlying health issue going on.
Buddy...
You couldn't be more wrong if you tried to be.
If someone can eat fast food and their stomach is fine, it means their gut biome is used to that shit. And if they ever ate healthy, then that would fuck their stomach up, until their gut biome gets used to healthy food.
When people say fast food fucks their stomach, telling them you can handle it is not a flex.
It just means you e normalized eating insanely unhealthy food to the point your body has adapted to it, and you desperately need help with your health
But because you're acting the way you are, very few people would be willing to explain this to you...
