Introduction: Cardiovascular diseases (CVDs) are the leading cause of global mortality, despite being preventable. Moderate wine consumption has been associated with one of the preventative approaches due to its benefits on cardiovascular health, including endothelial protection and antioxidant effects, attributed to its chemical composition, such as flavonoids. Objective: To assess endothelial function through flow-mediated dilation after the consumption of red wine compared to non-alcoholic wine. Methodology: A parallel, randomized, placebo-controlled clinical trial with a blinded evaluator will be conducted with 20 healthy participants, evaluated at two distinct time points. Participants will be selected to receive either red wine or non-alcoholic wine and will be crossed over after 7 days to receive the opposite beverage from the initial one. The primary outcome will be the change in flow-mediated dilation of the brachial artery pre- and post-intervention in both groups. The secondary outcomes will include the flow-mediated dilation values, brachial artery diameter after the intervention, and measurements of systolic blood pressure (SBP) and diastolic blood pressure (DBP).

Flow-mediated dilation
Evaluate flow-mediated dilation after the consumption of red wine compared to placebo
Time frame: 40 minutes after the substance intake
Heart rate
Analyze the difference in heart rate (in bpm) after the consumption of red wine compared to the consumption of non-alcoholic wine.
Time frame: 40 minutes after the substance intake
Blood pressure
Analyze the difference in blood pressure (in mmHg) after the consumption of red wine compared to the consumption of non-alcoholic wine.
Time frame: 40 minutes after the substance intake
Brachial artery diameter at rest
Evaluate the difference in the diameter (at rest) of the brachial artery (measured in millimeters) before and after consuming red wine.
Time frame: 40 minutes after the substance intake
Brachial artery diameter after endothelial stress
Evaluate the difference in the diameter (after endothelial stress) of the brachial artery (measured in millimeters) before and after consuming red wine.
Time frame: 40 minutes after the substance intake
