re: When people say they need to run to the bathroom after eating certain foods?

Certain people can have food sensitivities.


In addition, IBS (irritable bowel syndrome) is pretty common. I don't think they know the exact cause of it.

Personally, I believe its at least partially because we're narrowing down the biome of our digestive system through processed/sugary foods and antibiotic use. Not many people know that you have more bacteria in your digestive system than you have of your own cells in your body.
