The Influence of Chardonnay Marc Intake on Gut and Cardiometabolic Health
Source: ClinicalTrials.gov · Last updated 7 Aug 2026
Brief summary (registry, in English)
Recently a dietary recommendation of 400 - 600 mg/ day has been proposed for the reduced risk of developing cardiovascular disease. Dietary flavanols can be obtained from the intake of foods such as tea, cocoa, wine, berries and apples. Incorporating Chardonnay Marc (the skins and seeds of Chardonnay grapes) into the diet can be an additional source of dietary flavanols. Like other flavanol-rich foods, Chardonnay Marc provides fiber and polysaccharides that may benefit gut health. This study seeks pilot data on the impact of the daily incorporation of Chardonnay Marc powder into the diet on markers of gut and cardiometabolic health.
