>Fried, greasy, and fatty foods - Foods that are high in saturated and trans fats can cause diarrhea or make symptoms worse. The extra fat is broken down in the colon (large intestine), which causes the release of extra fluids that cause a bout of diarrhea.
Literally the only food I enjoy will give me problems on the other end.
This is what sucks about ageing. Something that was fine for over 30 years is suddenly not fine, and never will be again.
