What are polyphenols?

Polyphenols include several classes of phytonutrients, including flavanols found in cranberries, that are naturally occurring in fruits and vegetables. In addition to their antioxidant capacity, polyphenols have been shown to provide protection from some bacterial pathogens, cancer, cardiovascular disease and inflammation.


What are Proanthocyanidins (PACs)?

Proanthocyanidins (PACs) are in the flavanol family – a class of polyphenols. The PACs found in cranberries have a different structure than those found in other fruits and vegetables which are associated with their anti-adhesion properties. Cranberry PACs help prevent the adhesion of certain harmful bacteria, including E. coli associated with urinary tract infections, onto cell walls.


What is an antioxidant?

Antioxidants are compounds that neutralize free radicals when they are formed. The human body is capable of producing antioxidants naturally, but under conditions of stress this antioxidant production can be severely impaired. Fruits and vegetables, including cranberries, provide an excellent source of additional antioxidants.


What is a free radical?

Normally the molecules that make up our body have an even number of electrons orbiting around a nucleus. A free radical is any molecule with an odd number of electrons. These "unstable" molecules attempt to "stabilize" themselves by capturing an electron from another molecule. The cells in the body where this process is occurring can become injured. The cell may malfunction or even become malignant.


How are free radicals produced in the body?

The body produces free radicals through normal metabolic pathways (i.e. extracting energy from the food we eat). Exposure to the sun's ultraviolet radiation, tobacco smoke, and exposure to certain naturally occurring chemicals can also be sources of free radical production. In short, we are exposed to potential sources free radical production every day of our lives.

Where are cranberries grown today?

While commercial farms exist in nearly a dozen states, Wisconsin, Massachusetts, New Jersey, Oregon, Washington, and the Canadian provinces of British Columbia and Québec account for most of the production worldwide. Production is also expanding in Chile.


How many cranberries are grown each year?

In 2018, a total of 1.31 billion pounds of cranberries were produced in the U.S., Canada and Chile. The U.S. Cranberry Marketing Committee website provides current and historical crop statistics and information for the U.S. only.


Do cranberries grow in or under water?

No. It is a common misconception that cranberries are grown in water. Water is used during harvest to float the fruit for easier collection, and during the winter months to protect the plants from freezing and desiccation. The rest of the year the fruit is grown on dry beds.


Do cranberries grow on a tree or a bush?

Neither. The American Cranberry (Vaccinium macrocarpon) is a low-growing, vining, woody perennial plant with small, alternate, oval leaves. The plant produces horizontal stems or runners up to 6 feet (2 m) long. Short vertical branches 2 to 8 inches (5 to 20 cm) in height, called uprights, grow from buds on the runners and produce both vegetative and fruit buds. Each fruit bud may contain as many as seven flowers.


Where can I find nutritional information on cranberries?

The USDA's National Nutrient Database for Standard Reference provides nutritional data for raw cranberries, dried cranberries, cranberry sauce and cranberry juice cocktail.
