How healthy is red wine without alcohol?
On another occasion, the men drank the same amount of dealcoholized red wine for 4 weeks.
On yet another occasion, the men drank three glasses of gin every day. The gin delivered just as much alcohol as the red wine, but didn't contain phenolic compounds.
Red wine increased the concentration in the blood of the vasodilator nitric oxide [NO] by 0.6 micromol per liter. The effect of red wine without alcohol on the concentration of nitric oxide was significantly greater. Gin had no effect on nitric oxide.
"Dealcoholized red wine decreases systolic and diastolic blood pressure through a NO-mediated mechanism", write the reserachers. "The daily consumption of dealcoholized red wine could be useful for the prevention of low to moderate hypertension."
"Although the blood pressure reduction after dealcoholized red wine consumption was modest (5.8 and 2.3 mmHg of systolic and diastolic blood pressure, respectively), decreases of 4 or 2 mm Hg in SBP or DBP respectively have been associated with a 14% and 20% reduction in CHD and stroke risk."
Red grape juice probably also works, we add. Or supplements with extracts from grapes.
