Nutrition Raw cranberries are 87% water, 12%
carbohydrates, and contain negligible
protein and
fat (table). In a reference amount of , raw cranberries supply 46
calories and moderate levels of
vitamin C,
dietary fiber, and the
dietary mineral manganese (each with 16% of its
Daily Value), while other
micronutrients are low in content (table).
Dried cranberries are commonly sweetened by adding
sucrose with up to 17 times of their natural
sugar content. The drying process also eliminates vitamin C content. In James Rosier's book
The Land of Virginia there is an account of Europeans coming ashore and being met with Native Americans bearing bark cups full of cranberries. In Plymouth, Massachusetts, there is a 1633 account of the husband of Mary Ring auctioning her cranberry-dyed petticoat for 16 shillings. In 1643,
Roger Williams's book
A Key into the Language of America described cranberries, referring to them as "bearberries" because bears ate them. In 1648, preacher John Elliott was quoted in
Thomas Shepard's book
Clear Sunshine of the Gospel with an account of the difficulties the Pilgrims were having in using the Indians to harvest cranberries as they preferred to hunt and fish. In 1663, the Pilgrim cookbook appears with a recipe for cranberry sauce. In 1667, New Englanders sent to
King Charles ten barrels of cranberries, three barrels of codfish and some Indian corn as a means of appeasement for his anger over their local coining of the
pine tree shilling minted by
John Hull. In 1669, Captain Richard Cobb had a banquet in his house (to celebrate both his marriage to Mary Gorham and his election to the Convention of Assistance), serving wild turkey with sauce made from wild cranberries. In the 1672 book
New England Rarities Discovered, author
John Josselyn described cranberries, writing:Sauce for the Pilgrims, cranberry or bearberry, is a small trayling plant that grows in salt marshes that are overgrown with moss. The berries are of a pale yellow color, afterwards red, as big as a cherry, some perfectly round, others oval, all of them hollow with sower astringent taste; they are ripe in August and September. They are excellent against the Scurvy. They are also good to allay the fervor of hoof diseases. The Indians and English use them mush, boyling them with sugar for sauce to eat with their meat; and it is a delicate sauce, especially with roasted mutton. Some make tarts with them as with gooseberries. ''The Compleat Cook's Guide
, published in 1683, made reference to cranberry juice. In 1703, cranberries were served at the Harvard University commencement dinner. In 1787, James Madison wrote Thomas Jefferson in France for background information on constitutional government to use at the Constitutional Convention. Jefferson sent back a number of books on the subject and in return asked for a gift of apples, pecans and cranberries. William Aiton, a Scottish botanist, included an entry for the cranberry in volume II of his 1789 work Hortus Kewensis. He notes that Vaccinium macrocarpon (American cranberry) was cultivated by James Gordon in 1760. In 1796, cranberries were served at the first celebration of the landing of the Pilgrims, and Amelia Simmons (an American orphan) wrote a book entitled American Cookery'' which contained a recipe for cranberry tarts.
Products As fresh cranberries are hard, sour, and bitter, about 95% of cranberries are processed and used to make
cranberry juice and sauce. They are also sold dried and sweetened. Usually cranberries as fruit are cooked into a
compote or
jelly, known as
cranberry sauce. Such preparations are traditionally served with roast
turkey, as a staple of Thanksgiving (both
in Canada and
in the United States) as well as English dinners. The berry is also used in baking (
muffins,
scones, cakes and
breads). In baking it is often combined with orange or
orange zest. Less commonly, cranberries are used to add tartness to savory dishes such as soups and stews. There are several alcoholic cocktails, including the
cosmopolitan, that include cranberry juice.
Urinary tract infections A 2023
Cochrane systematic review of 50 studies concluded there is moderate evidence that consuming cranberry products (such as juice or capsules) may reduce the risk of
urinary tract infections (UTIs) in women with recurrent UTIs, in children, and in people susceptible to UTIs following clinical interventions; there was little evidence of effect in elderly people, those with
urination disorders or pregnant women. When the quality of
meta-analyses on the efficacy of consuming cranberry products for preventing or treating UTIs is examined with the weaker evidence that is available, large variation and uncertainty of effects are seen, resulting from inconsistencies of
clinical research design and inadequate numbers of subjects. In 2014, the
European Food Safety Authority reviewed the evidence for one brand of cranberry extract and concluded that a
cause and effect relationship had not been established between cranberry consumption and reduced risk of UTIs. A 2022 review of international
urology guidelines on UTI found that most clinical organizations felt the evidence for use of cranberry products to inhibit UTIs was conflicting, unconvincing or weak. == Research ==
