Is Wine Actually Good for Your Heart?

Updated July 2026

For years, we were all told the same reassuring thing: a daily glass of wine is good for your heart. It is one of the most repeated pieces of health advice of the last few decades. I have embraced that myself, with one glass of red wine most evenings.

The problem is that the latest and best evidence says the story does not really hold up. Here is what changed, and what it means for all of us.

Where did the idea that wine is good for your heart come from?

It came from large population studies that seemed to show moderate drinkers had less heart disease than people who did not drink at all. That pattern, often called the J-shaped curve, was real in the data, and it launched decades of headlines. A J-shaped curve points to a sweet spot. Heavy drinking clearly raised the risk of disease, but in these studies people who drank nothing looked slightly worse off than those who drank a little. So moderate consumption appeared to be that sweet spot.

Unfortunately, those studies had a hard time separating the wine from everything else about the people drinking it. Moderate drinkers tend to be wealthier, more physically active, and healthier to begin with. And the "non-drinker" group often included people who had quit drinking because they were already sick, which made the drinkers look healthier by comparison. In other words, the apparent benefit may have had less to do with the alcohol than with who was doing the drinking.

What does the newer, better research show?

It points to little or no heart benefit from moderate drinking, and it does not support drinking for your health. A more rigorous type of study, which uses people's genes to estimate the effects of alcohol and is far less prone to those earlier biases, has found no cardiovascular benefit and signs of harm even at lower levels of drinking. In 2025, the American Heart Association reviewed all of this and issued a scientific statement concluding that the latest evidence suggests little or no protection, while the harms of heavier drinking remain clear and consistent. The World Health Organization has gone further, stating that no level of alcohol consumption is completely safe. The takeaway is that the protective glass of wine was, in all likelihood, largely a statistical illusion.

But didn't a study show wine improved cholesterol?

It did, but not enough to warrant recommending alcohol as a cholesterol management tool. A two-year trial in people with well-controlled diabetes, all following a Mediterranean diet, found that a daily 5 ounce glass of red wine raised HDL, the "good" cholesterol, by about 2 mg/dL, while white wine modestly lowered blood sugar, and both slightly improved triglycerides. Those changes were real, but they were small, they occurred in one specific group of people, and, most importantly, the study never showed that drinking wine prevented a single heart attack or stroke. The same improvements, and bigger ones, come from changing your diet, losing weight, and moving more, without any of the downsides that come with alcohol.

What about the cancer risk?

This is the part that was barely on the radar when the "wine is healthy" idea took hold, and it changes the whole calculation. In 2025, the U.S. Surgeon General issued an advisory identifying alcohol as a leading preventable cause of cancer, linked to at least seven types, including breast, colorectal, liver, esophageal, mouth, throat, and voice box cancers, and called for cancer warning labels on alcoholic drinks. The risk is not limited to heavy drinking. For some cancers, including breast cancer, the risk begins to rise at as little as one drink a day. So whatever small effect alcohol might have on a cholesterol number has to be weighed against a genuine, well-established increase in cancer risk. Honestly, I consider this the biggest argument against imbibing.

So should I drink wine for my heart?

If you do not currently drink, this is not a reason to start, and no credible health authority today recommends taking up drinking for cardiovascular benefit. If you do drink and enjoy it, the guidance is simply that less is better, and small, consistent amounts carry less risk than saving it all up for the weekend. Personally, I am going with that. I am also finding ways to consume less without feeling deprived, like having a wine spritzer some nights instead of a full glass of wine. All the enjoyment with half the alcohol and calories.

A big point: some people should not drink at all. This includes anyone with a personal or family history of addiction, people with certain medical conditions or medications, and anyone who is pregnant. And it is worth remembering where the famous Mediterranean-diet benefits actually come from. They come from the vegetables, whole grains, beans, nuts, olive oil, and fish, not from the wine.

What about mocktails and zero-proof beverages?

On the alcohol front, they are clearly winners. But that does not make them automatically good for us. A virgin pina colada can still come in at 400 calories, and there is generally nothing health promoting in a zero-proof beverage. Having said that, the wide availability of mocktails and choices like zero-proof beer has helped lessen the pressure to drink alcohol in social settings. And that is good for all of us.

What actually protects your heart?

The things that have always worked, and that no drink can replace. Eat real food in its whole, natural form. Move your body most days. Keep your weight, blood pressure, blood sugar, and cholesterol in a healthy range. Those are the levers with decades of consistent evidence behind them, and they carry no cancer risk in return.

That is the entire premise behind Step One Foods. We put meaningful doses of the fiber, phytosterols, and omega-3s shown to lower cholesterol into two simple servings a day, and we proved it works in a randomized controlled trial conducted with Mayo Clinic and the University of Manitoba. If your goal is a healthier heart, that is where the real return is, on your plate, not in your glass.
