Do certain foods stay in your system longer than others?

Last year, I went to Chic-Fil-A, and got a simple order: a chicken sandwich (the chicken was not grilled), and waffle fries. I also had water. After I had eaten that, my flatulence had the same smell for a couple days. I've eaten fried food before, but that was the first time I had eaten a full meal from Chic-Fil-A.
