One of the major flavonoids in cranberries is quercetin. It is found to be a good anti-inflammatory and is particularly effective if used in the early stages of an inflammation. It is also known to have iron-binding capabilities.
Another flavnoid that is found in dried cranberries is myricetin which is recognized as an antioxidant. Myricetin is said to have the ability to fight prostate cancer in particular and is effective on the whole in fighting carcinogens.
On the whole, dried cranberries have a lot to offer. For such a small berry, they pack a huge nutritional boost. I use them in all kinds of dishes, and as often as possible. We love them in our house. Give them a try and see if you don't fall in love with them as well.
