                                According to the Centers for Disease Control and Prevention (CDC), a standard drink in the U.S. contains 0.6 ounces of pure alcohol. Understanding this definition is the crucial first step when asking how many servings of alcohol a day are appropriate, as recommended limits vary based on factors like age and gender, and recent research indicates even moderate consumption carries risks.
