Observing how cocoa effects the cardiovascular and renal system.
Study designed to assess the vascular benefits of drinking Cocoa that is rich in polyphenols. Vascular beds studied will include kidney, brain, eye, and periphery (finger). Time course of the effects will be studied in healthy normal (including elderly), and also in subjects with Type I and Type II diabetes. Renal blood flow will be determined by PAH/In u test clearance. Cranial ultrasound will be used to measure brain blood flow. Retinal blood flow will be assessed by specialized ultrasound/doppler device. Peripheral blood flow is measured by plethysmography. Urine and blood samples will be assayed for routine physiologic parameters, including hormone assessment, and also for the presence of cocoa metabolites.
