Nutrition Facts for Dried Prunes

Prunes are marketed as a fruit snack, but you can use them in a variety of recipes ranging from soufflés and puddings to cakes and muffins. This unique-tasting fruit is well known as being an excellent source of fiber; however, prunes also provide other essential nutrients.

Understanding Prunes

In 2001, plum growers won the FDA's approval to start calling prunes "dried plums." Plum growers requested the name change because they wanted to de-emphasize the reputation of prunes as a laxative and remarket them as a nutritious fruit snack, according to the California Dried Plum Board. The new name commonly gets mixed-up with the old and as such, they’re often referred to as dried prunes, instead. Since prunes are actually dried plums, calling them dried prunes is not quite accurate. Prunes can be further dehydrated so that all the moisture is removed. When this occurs, the resulting dehydrated, low-moisture prunes are technically, dried prunes, although they are typically referred to as just dehydrated prunes. Dehydrated, low-moisture prunes are a small, very dry product that’s suitable for cooking, but not edible as a fruit snack.
