Brief Summary
The objectives of this study are the following: 1) to confirm that the administration of grape juice, resveratrol, and grape seed polyphenol extract results in a similar plasma and urinary metabolic profile in aged humans compared to rats, 2) to confirm that a combined administration of grape juice, resveratrol, and grape seed polyphenol extract result in a similar plasma and urinary metabolic profile in adults with tendencies toward metabolic syndrome compared to non-obese healthy humans, and 3) to identify the anti-inflammatory effects of the combined administration of grape juice, resveratrol, and grape seed polyphenol extract.
