Many have been touting the benefits of red wine, but a new study shows that non-alcoholic red wine may be best for men's cardiovascular health.

According to researchers at the Hospital Clinic of Barcelona, drinking moderate amounts of non-alcoholic red wine for four weeks was able to reduce systolic and diastolic blood pressure. Drinking alcoholic red wine, however, did not lead to any significant changes.
The study was published online on Sept. 6 in Circulation Research.
For the study, researchers asked 67 men with diabetes or three or more cardiovascular risk factors - including high blood pressure, high cholesterol, being overweight or obese, smoking or a family history of coronary heart disease - to spend four weeks drinking either 10 ounces of red wine, 10 ounces of non-alcoholic red wine or 3 ounces of gin daily. After the four week period, they switched to a different beverage and then switched again until they consumed all three beverages.
Men who drank the non-alcoholic red wine had an average deduction of 6mmHg in systolic and 2mmHg diastolic blood pressure, equaling a reduction of heart disease risk by 14 percent and stroke by as much as 20 percent.
The alcoholic and non-alcoholic red wine had the same amounts of polyphenols, an antioxidant that decreases blood pressure. This lead researchers to believe the alcohol in the red wine may be lowering the substance's effect to lower blood pressure.
"The non-alcoholic part of the wine -- namely polyphenols -- exert a protective effect on the cardiovascular system," researcher Dr. Ramon Estruch, senior consultant at the internal medicine department of the Hospital Clinic of Barcelona in Barcelona, Spain, said to WebMD. "Polyphenols also have anti-inflammatory and antioxidant properties that may be useful to prevent other disease such as diabetes."
