Beer: a vice or a staple part of the diet?

Were we able to transport ourselves back to the Middle Ages and enquire in England, Flanders, Bavaria or Bohemia about the key features of the popular diet, ale or beer would unquestioningly and unhesitatingly be listed alongside meat, bread, milk and vegetables. The questioner would be regarded as being mightily peculiar if he or she were to question ale’s legitimate place on the table. It was neither a comfort food nor an extravagance. It was an integral part of the food intake in all walks of society. In eighth-century England a monk might consume eight pints of ale a day. Beer in Britain has long been considered to be a key part of the diet, as much so as wine in France. Henry Brougham MP (Brougham 1830) said that ‘To the poor the beer is next to a necessity of life.’
Over 50 years ago the nutritive value of beer was emphasised. An admittedly weakish beer [3% alcohol by volume (ABV) in the austere early post-war years] was claimed to provide 200 calories and a fth of a working man’s requirement for calcium, phosphorus,nicotinic acid and ribo avin (Bunker 1947). The satisfaction of having at least part of one’s dietary intake in a pleasurable form was not sneered at then.
Perhaps the rst person to conduct a serious study of the impact of abstinence, moderation and excessive drinking on health was statistician Raymond Pearl. On the basis of interviews with over 2000 workers in Baltimore, he concluded almost 80 years ago that on average moderate drinkers lived longer than abstainers and much longer than those who were heavy drinkers (Pearl 1926).
Yet now, at the dawn of the twenty- rst century, beer-drinking is regarded in many societies as a vice. It is surely astonishing that in the United States it is possible to buy cigarettes at the age of 18, but it is not legal to purchase alcohol until the age of 21. It would be a struggle to identify any merit associated with smoking, with the possible exception of its role as an anxiety relaxant. By contrast there is accumulating evidence that alcohol, including beer, in moderation can have a bene cial impact on health and wellbeing.
In passing, let us consider the legal age at which, in the US, it is possible to partake of other activities that surely might be considered a genuine risk to health and wellbeing, not only for the partaker but also for those around them. A child may legally drive a car, with relatively few restrictions, at the age of 16. More alarmingly, 35 states in the US have no licensing or registration requirements for guns (www.soros.org/crime/ higlights.htm). Seven states lack a legal minimum age for buying a ri e or shotgun from an unlicensed dealer, while six states have no legal minimum age for a child to possess a handgun. In ve states there is a minimum age – 16 in New York, Georgia, Vermont and Alaska, and just 14 in Montana. But the minimum legal age for drinking alcohol in all 50 states is 21!
Opinions about the relative merits and de-merits of smoking, driving, guns and alcohol will of course differ between individuals. Certainly if we consider the respective virtues of smoking, weapon use and alcohol (in restraint), then it seems to this author that there may be a warped set of priorities in one country at least. Nonetheless beer is the second most popular drink in the United States, with annual average per capita consumption at 357 8-ounce servings, after sodas and other soft drinks (861) (Beverage Digest 1998). Worldwide production of beer in 1999 ran at 0.13 billion litres.
