Concord grape juice contain flavonoids which have an antioxidant effect. A study conducted on men with metabolic syndrome revealed that grape polyphenols may increase vasorelaxation which has a direct effect on reducing blood pressure. The study also suggested it reduced circulating cell adhesion, thus improving vascular function. This study was conducted on men with metabolic syndrome. Metabolic syndrome is defined as a cluster of conditions occurring together which increase a person’s cardiovascular risk. These include high blood pressure, elevated blood sugar or insulin resistance, elevated triglycerides contributing to arterial disease, and central obesity. These often not only occur together but have similar causes, mechanisms and processes. One can certainly see the significance of improving cardiovascular health. After all, cardiovascular disease is a major cause of death and disability in the United States. A diet low in saturated fats, low in sugar and refined carbohydrates accompanied by moderate to regular exercise can decrease our risks of cardiovascular disease. Incorporating these tidbits into our everyday lives will not only help prevent disease but can help us feel better. So drink your concord grape juice or red wine in moderation.
