Red wine does not protect the heart.

Short answer
No. The heart-healthy red wine story does not hold up. The French Paradox and the resveratrol claims are called debunked. The famous J-curve is likely a "sick-quitter" artifact, and wine is far too dilute in resveratrol to matter. Alcohol raises blood pressure and heart-attack risk. Zero is the safest baseline.

A claim from podcasts on this question, checked against the studies that test it.
Of 10 studies that test it, 6 agree and 4 partly agree.
Red wine does not protect the heart. The idea comes from two places, the French Paradox and resveratrol, and neither holds up.
The apparent benefits rest on flawed readings of the epidemiology, and the resveratrol longevity claim is called debunked. Andrew Huberman, on his own show, says most of the resveratrol lifespan thinking has been debunked. A glass may help you unwind, but it does nothing for your health. Ethanol is a toxin with no clear benefit to the body.
The long-assumed protection from moderate drinking is likely the "sick-quitter" artifact. Studies count former heavy drinkers as abstainers, which makes the abstainers look sick. Large analyses then show a clear dose-response, which undercuts the idea of a universal protective J-curve.
The compound behind the hype does not rescue it either. Wine holds far too little resveratrol to produce the effects seen in high-dose studies.
Alcohol raises blood pressure, triglycerides and heart-attack risk while it suppresses immunity. It is a toxin with no nutritional value, and cancer risk rises even at low intake. Industry-funded research helped shape the heart-healthy story. Even one drink degrades sleep, raising resting heart rate and dropping HRV.
A single glass is not poison. 1-2 drinks a week may not measurably raise mortality against abstaining. Any heart signal may hold for healthy men and not for women or people with hypertension. That makes a small amount of red wine harm reduction rather than a heart tonic. If you want the antioxidants, eat grapes and berries and skip the ethanol.
