Overview
About Prune
Prunes are famous as a natural laxative, and the reason is right there in the trigger data: dried plums are loaded with sorbitol (a polyol) and excess fructose, both poorly absorbed FODMAP sugars that pull water into the gut.
That same pile-up makes them a strong FODMAP trigger, and prunes are also high in salicylates and oxalates and rate high for sulfites. If prunes give you gas, cramping, urgency or loose stools, that is the mechanism working overtime, not a coincidence.

How Prune scores
Watch for
What trips people up
- High in sorbitol and excess fructose, the two poorly-absorbed sugars behind the classic prune laxative effect and a lot of bloating and cramping
- High FODMAP overall, so even a few can set off gas, urgency or loose stools in a sensitive gut
- High in salicylates and oxalates, two separate triggers that matter if you react to aspirin-type foods or are prone to calcium-oxalate kidney stones
- Rated high for sulfites, a preservative common across dried fruit and a trigger for some people with asthma or sulfite sensitivity

FAQ
Common questions about Prune
Why do prunes work as a laxative?
Prunes are packed with sorbitol, a sugar alcohol your body absorbs poorly, plus fructose in excess of glucose and a lot of fiber. The unabsorbed sorbitol and fructose draw water into the colon and ferment, which softens stool and speeds transit. That is the same FODMAP overload that causes the bloating and cramping some people feel.
Are prunes low FODMAP?
No. Prunes are high FODMAP, driven mainly by sorbitol (a polyol) and excess fructose. Monash rates even a small serving as high, so they are one of the dried fruits most likely to trigger IBS-type symptoms. Ripe banana is the safer sweet-snack swap if you are watching FODMAPs.
Do prunes contain sulfites?
Prunes rate high for sulfites in the trigger data. Sulfur-based preservatives are common across dried fruit, and dried fruit is one of the largest dietary sulfite sources, so prunes can be a problem if you are sulfite sensitive or have sulfite-triggered asthma.
