A few weeks ago I wrote a post on the top 12 trigger foods for people with Crohn’s disease or ulcerative colitis according to 9 research studies. This week we’re diving back into those studies to share the top 6 beverages that trigger symptoms according to IBD patients. 

Keep in mind that these studies were based on patient reported triggers...which may or may not be accurate. Sometimes it can be hard for people to identify all of their trigger foods or beverages so take these research study results with a grain of salt (or a splash of lime)!

Top 6 Beverages that Trigger Symptoms

(According to 9 Studies of Patient-Reported Symptoms)

  1. Milk/cream
  2. Alcohol
  3. Energy drinks and soda
  4. Coffee/tea
  5. Carbonated beverages
  6. Fruit juice
Top 6 trigger beverages according to 9 studies

Participants in 6 out of the 9 research studies reported that milk/cream most commonly triggered symptoms. Alcohol was reported as a trigger for study participants in 5 out of 9 studies.


Energy drinks (including soda), coffee and tea, as well as carbonated beverages were reported by study participants to trigger symptoms in 3 out of the 9 research studies. Fruit juice was reported to trigger symptoms in only one out of the 9 research studies.

Also, keep in mind that some of these beverages may not trigger symptoms for you, but are suggested in research studies to increase the growth of certain types of bad gut bacteria which may lead to worsening inflammation.

Others may just trigger symptoms but have no effect on inflammation. For instance, to my knowledge, no research suggests that coffee or tea increases bad gut bacteria but some patients have reported these beverages to worsen symptoms.
