Resveratrol and the Metabolic Syndrome
Resveratrol and the Metabolic Syndrome
Metabolic syndrome is a serious health condition that affects about 35 percent of adults and
 places them at higher risk of cardiovascular disease, diabetes, stroke and diseases related
 to fatty buildups in artery walls. The underlying causes of metabolic syndrome are obesity,
 being overweight, physical inactivity and genetic factors. In recent decades, the prevalence
 has increased dramatically in the United States. Lifestyle interventions including dietary
 modification, physical activity and weight loss form the basis of treatment for these
 patients. However, research has shown that even when people are able to incorporate these
 changes, they often revert back to their usual lifestyle resulting in weight gain and
 continued risk for diabetes and heart disease.

 Resveratrol, a natural plant derived compound found in grapes, peanuts and red wine, has been
 found to reverse some of the features of the metabolic syndrome (insulin resistance, high
 triglycerides, high blood pressure) in rodents. These improvements occurred without weight
 loss, and were proven to be a direct result of resveratrol ingestion. Other studies reveal
 improvement in cardiovascular health, tumor suppression, and longevity. However, there are
 few studies investigating these beneficial effects in humans. Investigators propose to prove
 that resveratrol, administered to subjects with the metabolic syndrome, under controlled
 conditions of weight stability, common diet, and strict compliance with the study drug, will
 improve the symptoms of the metabolic syndrome, thereby decreasing the chance of developing
 diabetes or heart disease.

 resveratrol research, the authors conclude that "in contrast to the lacking data of
 resveratrol in humans, the animal data are promising and indicate the need for further human
 clinical trials." Of the small clinical studies that have been done, the results are
 encouraging. Improvement in triglycerides, blood pressure and insulin resistance were noted.
 Resveratrol was well tolerated without serious side effects. These studies, however, did not
 recruit subjects with the metabolic syndrome, nor were they tightly controlled.

 The investigators propose to prove that resveratrol, administered to subjects with the
 metabolic syndrome, under controlled conditions of weight stability, common diet, and strict
 compliance with the study drug, will improve the symptoms of the metabolic syndrome, thereby
 decreasing the chance of developing diabetes or heart disease.
