A new study has revealed that drinking cranberry juice might
play a role in protecting against cardiovascular disease.
Researcher Rodriguez-Mateos of the University Duesseldorf
said that cranberry juice was a rich source of phytonutrients, including
proanthocyanidins, anthocyanins and phenolic acids. In the study, researchers
gave 10 healthy male subjects, between the ages of 18-40 years, 450 ml of
sweetened cranberry juice made from concentrate. The cranberry concentrate was
prepared with water to concentrations ranging from 0 to 117%.
Blood and urine samples were collected for 24 hours
following consumption to detect changes in plasma and urinary cranberry-derived
polyphenols. Across the board, all of the cranberry juices benefited
flow-mediated vasodilation (FMD) - including 25% cranberry juice, equivalent to
the commonly consumed cranberry juice cocktail. The highest concentration of
cranberry-polyphenol juice also showed improvements in systolic blood pressure.
Defending the health of the circulatory system and improving
vascular function, it not only reduced the chances of developing
atherosclerosis, but played an important role in kidney function, hormone
delivery and waste filtration. Rodriguez-Mateos said that their results laid
the groundwork to better understand the array of potential vascular and
cardiovascular health benefits of cranberry polyphenols, adding that the
significant improvements in vascular function from drinking two cups of
cranberry juice suggested an important role for cranberries in a heart-healthy
diet.
