Wild blueberries are a good source of phytochemicals called polyphenols, an organic compound associated with several health benefits, according to research conducted at the University of Maine.
The study, published in the journal Applied Physiology, demonstrated that a diet rich in blueberries may improve conditions associated metabolic syndrome, including cardiovascular disease and diabetes.
"The metabolic syndrome (MetS) is a group of risk factors characterized by obesity, hypertension, inflammation, dyslipidemia, glucose intolerance and insulin resistance, and endothelial dysfunction," said Dr. Klimis-Zacas, a Professor of clinical nutrition at the University of Maine and a co-author of the study.
"Mets affects an estimated 37 percent of adults in the US. Many substances found in food have the potential to prevent MetS, thus reducing the need for medication and medical intervention."
The team gave lab rats the human equivalent of two cups of wild blueberries per day. The rats showed an improved balance between the relaxing and constricting factors of the vascular wall, improved blood pressure and blood flow regulation.
