Diet for Diarrhea, Adult

ExitCare ImageFrequent, runny stools (diarrhea) may be caused or worsened by food or drink. Diarrhea may be relieved by changing your diet. Since diarrhea can last up to 7 days, it is easy for you to lose too much fluid from the body and become dehydrated. Fluids that are lost need to be replaced. Along with a modified diet, make sure you drink enough fluids to keep your urine clear or pale yellow.


  • Ensure adequate fluid intake (hydration): have 1 cup (8 oz) of fluid for each diarrhea episode. Avoid fluids that contain simple sugars or sports drinks, fruit juices, whole milk products, and sodas. Your urine should be clear or pale yellow if you are drinking enough fluids. Hydrate with an oral rehydration solution that you can purchase at pharmacies, retail stores, and online. You can prepare an oral rehydration solution at home by mixing the following ingredients together:

  • ⅓–⅔ tsp table salt.

  • ¾ tsp baking soda.

  • ⅓ tsp salt substitute containing potassium chloride.

  • 1 ⅓ tablespoons sugar.

  • 1 L (34 oz) of water.

  • Certain foods and beverages may increase the speed at which food moves through the gastrointestinal (GI) tract. These foods and beverages should be avoided and include:

  • Caffeinated and alcoholic beverages.

  • High-fiber foods, such as raw fruits and vegetables, nuts, seeds, and whole grain breads and cereals.

  • Foods and beverages sweetened with sugar alcohols, such as xylitol, sorbitol, and mannitol.

  • Some foods may be well tolerated and may help thicken stool including:

  • Starchy foods, such as rice, toast, pasta, low-sugar cereal, oatmeal, grits, baked potatoes, crackers, and bagels.  

  • Bananas.  

  • Applesauce.

  • Add probiotic-rich foods to help increase healthy bacteria in the GI tract, such as yogurt and fermented milk products.
