Plum
Plums are stone fruits with a thin skin and soft flesh containing sorbitol and phenolic compounds. They are notable for their natural laxative effect due to sorbitol and fiber content, particularly in dried form (prunes).
Also known as: Prunus domestica, prune (dried plum), fresh plum

Plums (Prunus domestica) are the fruit of temperate stone fruit trees, cultivated worldwide with major production in China, the EU, and North America. Available fresh, dried (prunes), or as juice, plums are consumed whole, cooked, or processed into jams and preserves. Varieties range from dark purple to yellow, with flavor profiles from tart to sweet depending on ripeness and cultivar.
A medium fresh plum (66g) contains approximately 30 calories, 7–8g carbohydrate, about 1g fiber, and negligible protein or fat. Plums provide a modest amount of vitamin C and potassium. The characteristic laxative effect comes from sorbitol, a sugar alcohol that draws water into the intestinal lumen, and fiber in the skin. Dried plums (prunes) concentrate these compounds, making them significantly more effective for bowel regularity than fresh plums.
Digestive and Bowel Function
Sorbitol in fresh plums and particularly in prunes is poorly absorbed in the small intestine and acts as an osmotic laxative. Clinical evidence supports dried plum consumption for mild constipation management, though individual response varies. Excessive consumption can cause osmotic diarrhea, abdominal bloating, and gas, especially in individuals sensitive to sorbitol or with irritable bowel syndrome. Whole plums eaten with skin intact provide both soluble and insoluble fiber, supporting normal intestinal transit.
Tolerance and Portion Guidance
Fresh plums are well-tolerated by many people in small amounts, but a single medium plum is considered high in sorbitol and may trigger digestive symptoms in sensitive individuals, particularly those with IBS or FODMAP sensitivity. Dried plums carry a higher sorbitol load per gram and may cause loose stools or bloating even in smaller quantities in sensitive individuals. Plums contain low to moderate levels of oxalates and are not high in histamine when fresh. People with fructose malabsorption or small intestinal bacterial overgrowth (SIBO) may experience symptoms from the sorbitol and fructose content. Plum juice is concentrated in sugar and sorbitol and should be consumed in limited quantities.
Frequently Asked Questions
Are plums high in sugar?
A medium fresh plum contains about 7–8g carbohydrate with a glycemic load considered low to moderate. Dried plums (prunes) are more concentrated in sugars, with roughly 18g carbohydrate per ounce (28g). Fresh plums are not a significant source of added sugar when eaten whole.
Do plums cause digestive upset?
Fresh plums contain sorbitol, which is poorly absorbed and acts as an osmotic laxative. Even a single medium fresh plum contains enough sorbitol to trigger bloating, gas, or loose stools in sensitive individuals, including those with IBS. Dried plums and plum juice contain even higher sorbitol concentrations and are more likely to cause symptoms.
Are plums safe for people with IBS?
Individual tolerance varies. The sorbitol and fructose content may trigger symptoms in IBS patients, particularly those with diarrhea-predominant IBS. A single whole plum is considered high in sorbitol, so those with IBS should start with very small portions and monitor their symptoms. A registered dietitian can help determine an appropriate amount for your situation.
