Page "Cranberry" Paragraph 41

One study compared cranberries with twenty other fruits, showing that cranberries had a high amount of total polyphenols.

Cranberry tannins have laboratory evidence for anti-clotting properties and may prevent recurring urinary tract infections in women, although the evidence in favor of cranberries ' efficacy in treating UTIs is far from conclusive.

Raw cranberries and cranberry juice are abundant food sources of flavonoids such as proanthocyanidins, flavonols and quercetin.

These compounds have shown possible activity as anti-cancer agents in vitro.

However, their effectiveness in humans has not been established, and is limited by poor absorption into cells and rapid excretion.
