Basically, any carb that goes right into blood sugar. Most carbs found in nature don’t spike blood sugar quickly but fast carbs most of which come from processed foods do.
You can turn slow carbs into fast carbs primarily by separating the fiber from them. For instance, whole blackberries would be slow carbs, but pulped juiced blackberries would be fast carbs because the sugars would hit your bloodstream very quickly.
I understand that cinnamon turns fast carbs into slow carbs. Is that also your understanding?
