Answer

In population studies, low levels of alcohol consumption have shown a favorable effect on BP, with reductions of 2-4 mm Hg. However, the consumption of 3 or more drinks per day is associated with elevation of BP. Daily alcohol intake should be restricted to less than 1 oz of ethanol in men and 0.5 oz in women. The 2011 ADA standard supports limiting alcohol consumption in patients with diabetes and hypertension. [71, 78]
