Thanks Miekal, that was really informative. I know here at the University of Louisville they are doing quite a bit of research on Anthocyanins and Polyphenols. I did go to a seminar that Dr. Gupta presented, and although all the colored fruits had these compounds, only blueberries had several types of them, which was key in preventing the growth of cancer cells. It is the variety of different types of Anthocyanins and Polyphenols that was most crucial in preventing/treating cancer in mice. I do not know if he has included Aronia in his research. I was not able to find the webpage outlining the specific research. I would guess that Aronia also has a variety of Anthocyanins and Polyphenols similar to blueberries.
Here is some of his research: http://php.louisville.edu/advancement/pub/impact/spring2005/applefull.php
I have purchased Aronia syrup, juice and jelly and found them all to taste really good. I would guess it is a processing issue perhaps that determines the taste.

ORAC, Oxygen Radical Absorbance Capacity, is the method that is used to measure the antioxidant capabilities of biological samples such as fresh fruits and vegetables. The ORAC value recorded for Aronia is about 58% higher in antioxidant levels than blueberries and over 90% more than cranberries. There are two major types of ORAC tests, H-ORAC and L-ORAC. Lipophilic and hydrophilic antioxidant capacities differ in the chemical makeup and how the breakdown time in our bodies digestive system.
Proanthocyanidins have benefits that are directly related to protection against Cardiovascular disease. Consumption of foods and beverages with high amounts of PAs and phenolic compounds is identified with the reduction of systolic blood pressure levels and a reduction of the total levels of cholesterol in the bloodstream. The concentration of PAs in the aronia berry is among the highest reported value of any food (Kelm, 613-617).
Anthocyanins are natural compounds that exhibit antioxidant activity and anti-inflammatory attributes. Anthocyanin rich extracts have been reported to inhibit growth of various cell lines. For instance, the University of Maryland completed a research study that demonstrated that the extract inhibited the cell growth of human colon cell lines.
Furthermore, it is attestable that it has accelerated anticancer and antitumor activity.
