In this episode of Daily Value, we examine the latest research on wine consumption and its relationship to cardiovascular health. Leveraging urinary tartaric acid as an objective biomarker, a recent study (PMID: 39689849) published in the European Heart Journal provides interesting evidence of a J-shaped association between wine intake and cardiovascular outcomes.

Discussion Points:

• Biomarkers and Bias: The role of urinary tartaric acid in providing a reliable objective measure of wine consumption, avoiding the recall and social desirability biases inherent in self-reported dietary studies.
• Mechanisms of Action: The potential cardioprotective effects light to moderate wine intake (are they real?)
• Dose-Dependent Effects: Insights into the J-shaped curve, revealing cardiovascular benefits with light-to-moderate consumption and increased risk with heavier intake.
