Diarrhea after eating – what to eat


I’m sure every person on the face of the planet has experienced a run in with “the runs”. Well diarrhea–known to many people as the runs– can make an occasional bothersome appearance, or it can be a frequent star in your daily routine. Your diarrhea could be from a number of different reasons. If you only occasionally experience a bout of diarrhea, especially diarrhea after eating out, then something in your food or the types of food you ingest are probably to blame.


A sensitivity to the foods you consume is probably the root cause of your diarrhea. If you usually experience diarrhea only when eating out, monosodium glutamate (MSG) is the likely culprit. Many restaurants use MSG in their food (especially in salads and Chinese food). When you go out to eat, ask the manager if they use it in any of their food preparation. Stay clear of any foods with MSG in it and see if you still have a bout of diarrhea.

Other foods or food substances that can contribute to diarrhea are:

  • Fatty or spicy foods             — these speed up intestinal contractions and can overly tax an already sensitized intestinal system.
  • Dairy products            — cause gas, bloating, nausea, and diarrhea in people who suffer from lactose intolerance. Dairy products to avoid are butter, ricotta or cottage cheese, milk and ice cream.
  • Sugar-free foods — artificial sweeteners and sugar substances can have a laxative effect. They can also cause gas and bloating. Avoid diet soda and anything else that says sugar-free on the packaging.
  • Gas producing foods — such as cabbage, cauliflower, beans, onions and broccoli  have also been well documented producers of intestinal gas and diarrhea.
  • Alcohol, caffeine, and carbonated drinks — although not generally known to cause digestive problems, some people can experience intestinal irritation and diarrhea when consuming these beverages.

Everything listed above should be eliminated one at a time until you find your diarrhea causing culprit or culprits. These are also the same things to avoid while experiencing a diarrhea episode.

Unsafe foods is also a possible reason for your diarrhea after eating. Any food/foods that have not been properly prepared and stored could be harboring harmful germs just waiting to wreak havoc with your intestines.

  • Always wash your hands before, during, and after preparing your meals.
  • Thoroughly wash all fresh produce.

  • Refrigerate or freeze leftovers immediately. Throw remaining leftovers away after three days, to lessen your risk of any digestive problems.



It is important to note that constant diarrhea after eating may be a sign you are suffering from irritable bowel syndrome (IBS) or an autoimmune disorder such as Crohn’s or ulcerative colitis.
