A prune is a dried plum of any cultivar, mostly the European plum (Prunus domestica). Use of the term "prune" for fresh plums is obsolete except when applied to varieties (of plum) grown for drying.
Prunes are 64% carbohydrates including dietary fiber, 2% protein, a rich source of vitamin K, and a moderate source of B vitamins and dietary minerals. The sorbitol content of dietary fiber likely provides the laxative effect associated with consuming prunes. Contrary to the name, boiled plums or prunes are not used to make sugar plums.
More than 1,000 plum cultivars are grown for drying. The main cultivar grown in the United States is the 'Improved French' prune. Other varieties include 'Sutter', 'Tulare Giant', 'Moyer', 'Imperial', 'Italian', and greengages. Fresh prunes reach the market earlier than fresh plums and are usually smaller in size.
In 2001, plum growers in the United States were authorized by the Food and Drug Administration to call prunes "dried plums". Due to a perception that prunes relieve constipation (perceived as derogatory), distributors stopped using the word "prune" on packaging labels in favor of "dried plums".
Prunes contain dietary fiber (about 7% of weight; table) which may provide laxative effects,. Their sorbitol content may also be responsible, a conclusion reached in a 2012 review by the European Food Safety Authority. 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.
Prunes are 31% water, 64% carbohydrates, including 7% dietary fiber, 2% protein, and less than 1% fat (table). Prunes are a rich source of vitamin K (57% of the Daily Value, DV) and a moderate source of several B vitamins and dietary minerals (10-16% DV; table).
