Non-Alcoholic Red Wine May Help Reduce High Blood Pressure, American Heart Association Reveals


9/7/2012 7:02:12 AM

DALLAS, Sept. 6, 2012 (GLOBE NEWSWIRE) -- Men with high risk for heart disease had lower blood pressure after drinking non-alcoholic red wine every day for four weeks, according to a new study in the American Heart Association journal Circulation Research.

Non-alcoholic red wine increased participants' levels of nitric oxide, which helped decrease both systolic and diastolic blood pressure, researchers said. Nitric oxide is a molecule in the body that helps blood vessels relax and allows more blood to reach your heart and organs.

Researchers studied 67 men with diabetes or three or more cardiovascular risk factors who ate a common diet plus one of the following drinks: about 10 ounces of red wine, non-alcoholic red wine or about 3 ounces of gin. All of the men tried each diet/beverage combination for 4 weeks.

The red wine and nonalcoholic wine contained equal amounts of polyphenols, an antioxidant that decreases blood pressure.

During the red wine phase, the men had very little reduction in blood pressure and there was no change while drinking gin. However, after drinking non-alcoholic red wine, blood pressure decreased by about 6mmHg in systolic and 2mmHg in diastolic blood pressure -- possibly reducing the risk of heart disease by 14 percent and stroke by as much as 20 percent.

Researchers concluded that the alcohol in red wine weakens its ability to lower blood pressure. But polyphenols -- still present after alcohol is removed from wine -- are likely the beneficial element in wine.
