A toast is in order! Recent research shows moderate alcohol consumption — defined as up to one drink a day for women and up to two for men — may improve immune system function and help us fight off infection. It’s important to keep in mind that the key is moderation. In the U.S., one drink means 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of hard liquor, such as gin or whiskey. Higher levels of drinking (more than seven drinks a week for women and 14 for men) may cause your efforts to backfire, harming the immune system, increasing blood pressure, and damaging heart muscle.
Research shows that moderate drinking can protect against cardiovascular disease, type 2 diabetes and gall stones. Cleveland Clinic
