Grape flavonoids and menopausal health

Grape flavonoids are members of a larger group of plant compounds called polyphenols. Epidemiological evidence relating to the traditional Mediterranean diet, which is high in polyphenols, derived from vegetables and red wine, suggests that dietary polyphenols are of benefit to health and reduce the incidence of cardiovascular disease. Overall, the evidence is promising for the benefit of grape flavonoids in the form of red wine, red grape juice and related preparations for cardiovascular risk factors. There are data to suggest a reduction in platelet activation, inflammation and low-density lipoprotein oxidation, and improvement of endothelial function with grape flavonoids. The evidence for grape flavonoids and renal function, cognition and cancer is less clear. However, it is important to note that much of this research has been carried out in animal and cell models; relatively little work has been done in humans and specifically on the health of menopausal women. There are no general safety concerns with ingestion of grape products. Obviously, consumption of red wine should be within recommended limits and it should be noted that grape juice has high sugar content. Grape flavonoids are also available as a supplement. In conclusion, it is likely that grape flavonoids do benefit the menopausal women. Further research is needed on the mode and dosage of application to maximize these benefits.
