Overhall health and nutrition profile is more important than the exact number of alcoholic beverages. A depressed inactive person ,surviving on sugar and coffee, who drinks 5 beers a day is more at risk then someone who has won the genetic lottery for being robust, has a pretty good diet and lifestyle. The risk to some people is maybe even pretty insignificant from the beers.
Still ,more than one ,or maybe two a day, is going to be some drain on health and day to day well being of most people, if not sooner, later. What may be o.k. in the 20’s could be too much later in life.
