Non-Alcoholic Red Wine for High Blood Pressure
New research published in the American Heart Association journal Circulation Research shows that drinking non-alcoholic red wine every day for four weeks can reduce the blood pressure in men who are at risk for heart disease.
The researchers compared the effects of daily drinking of ten ounces of red wine, dealcoholized red wine or gin (3 ounces) combined with a common diet in 67 men. The men, who had diabetes or at least 3 cardiovascular risk factors, tried each combination for four weeks before shifting to the next. After each intervention blood pressure measurements as well as blood nitric oxide (NO) levels were taken.
Nitric oxide is a natural molecule in the body that relaxes blood vessels, allowing more blood flow to the heart and other organs. Although both red wine and non-alcoholic red wine contained equal amounts of polyphenols (antioxidants which can reduce blood pressure), the researchers noted that non-alcoholic red wine increased participants’ levels of nitric oxide, which led to the greater decreases of both systolic (upper number) and diastolic (lower number) blood pressure. There were no changes in blood pressure associated with gin.
The researchers conclude that the daily consumption of non-alcoholic red wine may be useful for the prevention of low to moderate high blood pressure.
