Polyphenols

'Prevention' discussed polyphenols and foods that contain them. In a short piece entitled 'Tart Heart Savers'1 a University of Wisconsin-Madison study was referenced which tested the effects of cranberries on pigs. Pigs were suitable animals to study because their circulatory system is similar to humans. These particular pigs were fed a diet that caused them to develop constricted arteries.

After six months of feeding these pigs cranberries it was noted that the blood vessels of the pigs became like those of healthy pigs who had not been bred to develop the arterial condition. The benefits of cranberries and polyphenols are well known. In addition to cranberries polyphenols can be obtained from a diet that includes black or green teas, chocolate, strawberries and pomegranates.
