I saw the tweet (above) yesterday. While it may be true that beer contains all 13 essential minerals (I say “may” because the nutrient profile only lists 11 minerals) I still think that this tweet is misleading. Oh sure, it’s all fun and games, until someone loses a liver. I enjoy a good beer as much as the next person, but I hate to think that anyone would believe that they can obtain all the nutrition that they need from beer.
Let’s assume that the two minerals not listed in the nutrient profile are indeed present in beer. There is certainly not enough of each of these minerals (some are present in extremely small quantities) to meet your daily requirements. For example, a female between the ages of 19 and 51 needs 18 mg of iron a day. One bottle of beer provides 0.7 mg of iron. That’s about 3.8% of the recommended intake for iron. Just for fun, that would mean drinking nearly 26 bottles of beer to meet your daily requirement.
The tweet also neglects to mention that there are other substances required for human life; such as, vitamins and macronutrients (carbohydrate, fat, and protein). Beer is lacking in all of these areas, aside from carbohydrate. Most of beers calories come from alcohol, which, unsurprisingly, is not an essential nutrient.
Another factor to consider: alcoholics tend to be one of the highest risk groups for nutrient deficiency (in the Western world). This is due to lack of consumption of nutrients from food, a need for more nutrients to repair the damage caused by excessive alcohol consumption, and impairment of digestion caused by alcohol consumption.
