Alcohol free wine could lower blood pressure and help stroke risk

Alcohol-free red wine may help to lower blood pressure levels to a greater extent than wine containing alcohol, according to new research that suggests the boozeless drink could cut heart disease and stroke risks.

Published in the journal Circulation Research​, the research finds that men with high risk for heart disease had lower blood pressure after drinking non-alcoholic red wine every day for four weeks.

The booze-free red wine – which contains the same levels of polyphenols as an alcoholic red wine – was found to increase levels of nitric oxide and thereby lower blood pressure in the study.

Led by Gemma Chiva-Blanch from the Hospital Clínic de Barcelona, Spain, the researchers added that the dealcoholised red wine was more effective at reducing blood pressure than red wine containing alcohol, and could help reduce the risk of heart disease and stroke.

“Dealcoholised red wine decreases systolic and diastolic blood pressure,” said​ Chiva-Blanch and her colleagues, who suggested that daily consumption of the alcohol-free wine “could be useful for the prevention of low to moderate hypertension.”

Study details

The researchers studied the effects of polyphenols and alcohol in 67 men with diabetes or three or more cardiovascular risk factors.

The participants ate a common diet, and were given one of three drinks to consume on a daily basis for four weeks (red wine, non-alcoholic red wine or gin). All participants received each drink/diet combination, with a ‘washout period’ before beginning the next.

Consumption of red wine phase resulted in a small reduction in blood pressure, while there was no change in BP from drinking gin, said the team.

After drinking the non-alcoholic red wine, however, the researchers revealed that blood pressure decreased by an average of 6mmHg in systolic and 2mmHg in diastolic blood pressure .

Chiva-Blanch and her colleagues said this blood pressure reduction roughly translates to a possible 14% risk reduction for heart disease and a lowering of the risk for stroke by as much as 20%.

The team concluded that the alcohol in red wine may weaken the ability of the polyphenols in red wine (and also present in the alcohol free wine) to lower blood pressure.

65 people for 4 weeks......?

Posted by chris aylmer,

Seems a bit shakey to me. Did the decrease disappear after the study or did they carry on drinking it?
Anyhow, where can you buy it in the UK and what does it taste like? If it tastes like most non-alcoholic wines I'll be giving it a miss. The alcohol intensifies the flavour of wine and when they remove the alcohol most of the flavour and aroma goes with it! Why is red grape juice not as good..presumably due to all the grape sugar consumed? What about powdered grape seed extract..that might be better than dealcolised wine if added to food and drink.

Not technically wine?

Posted by James D,

I was under the impression that the de-alcoholisation of wine is a process not currently allowed by the EU wine regulations ad therefore the prodcut cannot be referred to as wine. Has this changed recently?
