About Blueberry jamEdit
Wikipedia Article About Blueberry jam on Wikipedia
Blueberry jam is a jam made out of blueberries, sugar and water, and fruit pectin. Commercial jams often contain chemical preservatives like citric acid. Premium artisanal blueberry jam is produced in Canada and the United States from wild blueberries, which are smaller and more difficult to harvest but more intensely flavoured than cultivated blueberries. Most production is in Maine, northwestern Ontario, and in the Saguenay-Lac-Saint-Jean region of Quebec.
Blueberries, especially wild species, contain antioxidants which have been found to reduce the risks of some cancers. At the 2004 International Conference on Longevity, a group of researchers released details of a study that suggests certain compounds found in blueberries (and some similar fruits, including cranberries) have a significant impact in reducing the degradation of brain function, as in Alzheimer's Disease and other conditions). Research at Rutgers has also shown that blueberries may help prevent urinary tract infections.
