Coffee
The coffee having caffeine in it is remarkably good at fighting constipation. After you ingest a mug of coffee, the coffee particles increase the muscle contractions in the colon by two folds. The increasing of colon muscle contractions speeds up the digestion process, ultimately helping in the situation of constipation. But the key thing to remember is to stay hydrated while consuming coffee or tea, as it also increases the urination that might lead you to fluid loss.
