— Dark beer is more useful light

A team of scientists from the University of Valladolid in Spain (University of Valladolid) analyzed 40 brands of beer, and found that dark beer contains more iron than light and non-alcoholic, says Health24. According to experts, dark foamy drink is able to compensate for a deficiency of one of the most important trace elements in the human body.

According to the study, 40 beers from 5 continents, in a dark beer contains an average of 121 part per billion of iron ions in a light - 92, and drinks - 63.

According to one of the authors, Carlos Blanco, this difference may be due to specific features of the production process and raw materials used. In an article published in the publication Journal of the Science of Food and Agriculture, reports that a high iron content due to the fact that for the production of dark beer used extracts of malt and hops.

The production of light beer contains the filtration process using diatomaceous earth (sedimentary rock composed mainly of the remains of algae), under its influence, light beer gets its color. Diatomaceous earth also "connects" the iron ions, which leads to a decrease in their concentration. In non-alcoholic beer, iron ions are reduced because of alcohol use to remove the vacuum evaporation method. During this process, the iron ions are removed from the drink, along with volatile molecules.
