Non-Alcoholic Red Wine Lowers Blood PressureEditor's Choice Main Category: Nutrition / Diet Also Included In: Hypertension; Cardiovascular / Cardiology Article Date: 07 Sep 2012 - 11:00 PDT Non-Alcoholic Red Wine Lowers Blood Pressure Non-alcoholic red wine was found to lower blood pressure in men at high risk of heart disease, researchers from Spain reported in the journal Circulation Research. The authors explained that the men who drank non-alcoholic red wine daily for four weeks had higher levels of nitric oxide in their blood. Nitric oxide helps lower both systolic and diastolic blood pressure- the molecule helps blood vessels relax, allowing more blood to reach the body's organs, including the heart. Prior research has suggested that red wine polyphenols lower blood pressure in animals, but the effects of ethanol and polyphenols on blood pressure in humans had not yet been shown. In the current study, the team wanted to examine the impact red wine and non-alcoholic red wine have on blood pressure and nitric oxide in people at high cardiovascular risk. Investigators analyzed 67 males with diabetes or three or more cardiovascular risk factors who all consumed a similar diet plus one of these drinks: non-alcoholic red wine, 10 ounces of red wine, or 3 ounces of gin. Participants were randomized into three treatment periods, each lasted four weeks so all participants could try each diet/beverage combination. Polyphenols (natural antioxidants) present in red wine are good for heart health. However, the alcohol in red wine negates the benefits on blood pressure. When the subjects were drinking the red wine, they saw very little reduction in blood pressure, and while drinking gin, there was no change at all. However, during the non-alcoholic red wine phase, the guys experienced an increase in their levels of nitric oxide, which responds to the body's need for either an increase or decrease in blood flow by triggering blood vessels to open and close. The chemical relaxes the vessels and lets more blood to flow to the organs. This resulted in a decrease of the men's blood pressure of about 6mmHg in systolic and 22mHg in diastolic. The authors point out that this could also reduce the risk of heart disease by 14% and stroke by 20%. The alcohol in red wine disables the body's ability to lower blood pressure. However the polyphenols, which are still present even when the wine is non-alcoholic, are likely the key ingredient in wine that can make people healthier. Experts suggest a daily consumption of non-alcoholic red wine is beneficial in preventing high blood pressure.

Visitor Opinions (latest shown first) Black seeded grapes versus non- and alcoholic wine?posted by Peter mccann on 8 Sep 2012 at 3:05 am Now how about a trial comparing black seeded grapes with both non alcoholic and alcoholic wine. I am sure which would be the most beneficial.

Bitna razlikaCrno vino može vam spasiti život, ali postoji 'kvaka' Dobra vijest za ljubitelje crnog vina je da ono znatno snižava povišen krvni tlak. Loša je da iz njega prvo mora biti uklonjen alkohol. Studija je pokazala da su prirodni antioksidansi u crnom vinu dobri za zdravlje srca, piše Daily Mail. Ipak, znanstvenici iz Španjolske upozoravaju da alkohol slabi sposobnost crnog vina da snižava krvni tlak i učinkovito uništava svaku njegovu blagodat. Otkrili su da su muškarci sa srčanim bolestima imali niži krvni tlak nakon što su pili bezalkoholno crno vino svaki dan tijekom četiri tjedna. U istraživanju je sudjelovalo 67 muškaraca s dijabetesom ili tri ili više kardiovaskularnih rizičnih faktora, koji su imali uobičajenu prehranu kombiniranu s različitim pićima. Trebali su piti oko 3 dl crnog vina dnevno, ili istu količinu bezalkoholnog crnog vina ili oko 0,8 dl džina. Svi muškarci držali su se iste prehrane i pića tijekom četiri tjedna. Crno vino i bezalkoholno vino sadrže iste količine polifenola, antioksidansa koji snižava krvni tlak. Visok krvni tlak ili hipertenzija, koja se klasificira ako je tlak viši od 140/90 milimetrima žive (mm Hg), glavni je rizični faktor za srčane bolesti i moždani udar. Prva vrijednost označava sistolički tlak, visinu tlaka u arterijama kada se srce steže i otpušta krv u aortu. Druga vrijednost je dijastolički tlak, koji pokazuje visinu tlaka koji ostaje u arterijama između otkucaja kad se srce opušta i kad se puni krvlju. Oni koji su pili crno vino imali su vrlo malo smanjenje krvnog tlaka, dok kod onih koji su pili džin nije bilo nikakve promjene. Međutim, kod onih koji su pili bezalkoholno crno vino sistolički tlak smanjen je za oko 6, a dijastolički za oko 2, što je smanjilo rizik od srčanih bolesti za 14 posto, a od moždanog udara za čak 20 posto. Studija je objavljena u listu American Heart Association journal Circulation Research.
