Is Potato Good or Bad for Diarrhea?

4 min read

According to MedlinePlus, consuming high-potassium foods like potatoes can be beneficial when dealing with a bout of diarrhea. The seemingly simple question, "is potato good or bad for diarrhea?" actually has a nuanced answer that depends heavily on how the potato is prepared and consumed.

Quick Summary

The effect of potatoes on diarrhea depends on preparation; plain, cooked, and peeled potatoes can help symptoms by providing potassium and easy-to-digest carbohydrates, while skin and fatty preparations can worsen the condition.

Key Points

  • Boiled and Peeled are Best: For diarrhea, consume potatoes boiled or baked without the skin to reduce irritating fiber.

  • Replenishes Potassium: Potatoes are rich in potassium, an electrolyte lost during a bout of diarrhea.

  • Avoid Fatty Preparations: Steer clear of fried potatoes, buttery mashed potatoes, and other high-fat versions that can worsen symptoms.

  • Resistant Starch Benefits: Cooked and cooled potatoes contain resistant starch that acts as a prebiotic for gut health.

  • Gradual Reintroduction of Skin: Reintroduce the skin's fiber slowly as you recover to support long-term digestive health.

  • Part of a Bland Diet: Plain potatoes align with bland diets like the BRAT diet for soothing upset stomachs.

  • Consult a Professional: For persistent or severe diarrhea, a healthcare professional should be consulted for proper diagnosis and treatment.

The Dual Nature of Potatoes for Digestive Health

Potatoes are a versatile vegetable, and their effect on diarrhea is not straightforward. In general, plain, cooked potatoes are considered a good food choice for an upset stomach due to their blandness and nutrient content. However, preparation is key, as high-fat methods and including the fibrous skin can irritate the digestive system and exacerbate symptoms. Understanding this distinction is crucial for using potatoes as a home remedy.

Why Plain, Cooked Potatoes Can Help

When dealing with diarrhea, the body loses essential fluids and electrolytes, particularly potassium. Plain boiled or baked potatoes are an excellent source of this crucial mineral and are easy to digest.

  • Replenishes Potassium: One medium potato can provide a significant amount of potassium, which is vital for rebalancing electrolytes lost during diarrhea.
  • Binding Effect: Cooked potatoes (without the skin) are considered a "binding" food due to their starch content, which helps absorb excess water in the intestines and firm up stools.
  • Low in Fiber: By peeling the potato, you remove most of the insoluble fiber that could irritate the digestive tract. This makes it a safe, bland carbohydrate option.
  • Resistant Starch: When cooked potatoes are cooled, they develop resistant starch, a type of prebiotic fiber that feeds beneficial gut bacteria. This supports a healthier gut microbiome and can aid in recovery.

Why Potatoes Can Be Problematic

Not all potato preparations are suitable for those with diarrhea. The primary reasons a potato might cause issues are related to excess fiber, fat, and potential food sensitivities.

  • High Fiber in the Skin: The skin of a potato contains insoluble fiber, which speeds up digestion and can worsen diarrhea. For this reason, it is always recommended to peel potatoes when you have an upset stomach.
  • High-Fat Preparations: Foods like french fries, loaded mashed potatoes with butter and sour cream, or greasy hash browns are high in fat. Fatty foods can be hard to digest and can trigger or prolong diarrhea.
  • Allergy or Intolerance: While less common, some people have a food allergy or intolerance to potatoes. If you have digestive issues every time you eat them, regardless of preparation, it may be a sign of a sensitivity.

A Comparison of Potato Preparation for Diarrhea

Preparation Method Effect on Diarrhea Why? Best for Digestive Health?
Plain, Boiled Potato (Peeled) Good Bland, easy to digest, high in potassium, low in fiber. Acts as a binding agent. Yes
Plain, Baked Potato (Peeled) Good Similar to boiled, bland and provides potassium. Less moisture than boiled, but still effective. Yes
Fried Potato (e.g., French Fries) Bad High in unhealthy fats, which can trigger or worsen diarrhea and are hard to digest. No
Potato with Skin Bad Contains insoluble fiber that can irritate the gut and increase bowel movements. No
Mashed Potatoes (Plain) Good Easy to digest. Avoid adding high-fat dairy like butter or full-fat milk. Yes
Mashed Potatoes (Loaded) Bad Contains high-fat ingredients like butter, sour cream, and cheese that can exacerbate symptoms. No

The Role of Potatoes in the BRAT Diet and Beyond

Historically, the BRAT diet (Bananas, Rice, Applesauce, Toast) has been recommended for upset stomachs. Although not part of the original acronym, potatoes are often included as a bland, starchy food that is easy on the digestive system. The benefit of plain cooked potatoes aligns with the principles of the BRAT diet: providing simple carbohydrates and helping to bind stools.

For a truly integrative approach, incorporating resistant potato starch (available in supplement form) can also be beneficial for long-term gut health. This specific type of starch acts as a prebiotic, nourishing the good bacteria in the large intestine and promoting the production of short-chain fatty acids like butyrate, which is beneficial for colon health.

Conclusion

For those asking "is potato good or bad for diarrhea?" the answer is that the method of preparation is paramount. Plain, cooked, and peeled potatoes are a good choice to help bind stools, replenish lost potassium, and provide easily digestible energy. However, fatty potato dishes, and potatoes with the skin left on, can worsen symptoms due to their high fiber and fat content. Always opt for simple, bland preparations like boiling or baking without added dairy or fats. For persistent or severe diarrhea, it is always best to consult a healthcare professional. While potatoes can be a helpful part of a recovery diet, they are not a cure-all, and hydration remains the most important factor in recovery.

When to Reintroduce Potatoes with Skin

As your digestive health improves, you can gradually reintroduce potatoes with their skin. This is because the insoluble fiber in the skin is beneficial for long-term gut health by promoting regularity. The key is to monitor your body's reaction and increase your fiber intake slowly to avoid digestive discomfort. Always pay attention to your body's signals and adjust your diet accordingly.

Other Foods to Consider with Potatoes

  • White Rice: A classic binding food that pairs well with plain mashed potatoes.
  • Clear Broth: Helps with hydration and provides some nutrients without irritating the stomach.
  • Bananas: Another high-potassium, binding food commonly used with the BRAT diet.
  • Cooked Carrots: A bland, low-fiber vegetable that is easy on the stomach.
