Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Potato has been traditionally used in some cultures as a supportive food during episodes of diarrhea. This practice is based on the bland, starchy nature of potatoes, which are easy to digest and can help provide energy without irritating the gastrointestinal tract. Potatoes are also a source of potassium, an important electrolyte that may be depleted during diarrhea. Historically, in home and folk remedies, boiled or mashed potatoes (without added fats, spices, or dairy) have been recommended as part of the BRAT (Bananas, Rice, Applesauce, Toast) or similar bland diets for those recovering from gastrointestinal upset.

However, there is limited direct scientific evidence supporting the use of potatoes specifically to treat or shorten the duration of diarrhea. Most clinical guidelines focus on maintaining hydration and electrolyte balance, with some support for bland, low-fiber foods to help manage symptoms. Potatoes fit this profile, but their use is not uniquely validated over other starchy foods. The evidence largely comes from expert opinion and observational use rather than from controlled studies. Therefore, while the use of potatoes during diarrhea is supported by tradition and nutritional logic, its efficacy is not strongly validated by scientific research. The practice remains common as a safe, non-irritating food choice during recovery.
