Some artificial sugars do a number on my gut though
Do not eat any substantial amounts of candy containing xylitol. Stuff is a laxative, and lots of sugar-free candy and gum uses it.

Adverse effects
Humans
When ingested at high doses, xylitol and other polyols may cause gastrointestinal discomfort, including flatulence, diarrhea, and irritable bowel syndrome (see Metabolism above); some people experience the adverse effects at lower doses.[21][36] Xylitol has a lower laxation threshold than some sugar alcohols but is more easily tolerated than mannitol and sorbitol.[37]
