Prune

[3] A prune is the firm-fleshed fruit (plum) of Prunus domestica varieties that have a high soluble solids content, and do not ferment during drying.

The sorbitol content of dietary fiber likely provides the laxative effect associated with consuming prunes.

The great majority of commercially grown prune varieties are self-fertile and do not need separate pollinator trees.

[9] Their sorbitol content may also be responsible for this, a conclusion reached in a 2012 review by the European Food Safety Authority.

[10] The report also demonstrated that prunes effectively contribute to the maintenance of normal bowel function in the general population if consumed in quantities of at least 100 grams (3.5 oz) per day.
