Individuals who drink red wine for its polyphenol content, which has been associated with good heart health, may be interested to know that dark beers may also have some nutritional value.
In a study conducted by researchers at the University of Valladolid in Spain, it was found that dark beers — like stouts and porters — contain about 121 parts per billion (ppb) of iron, compared to 92 ppb in pale ales and 63 ppb in non-alcoholic beer.
“Although these quantities are very small, the differences are apparent and could be due to the production processes or raw materials used in manufacturing,” said co-author Carlos Blanco.
Beers with the highest iron content included Spanish varieties, found to have 165 ppb, and Mexican brews, with an estimated 130 ppb.The study indicated that the relatively high iron content found in dark beer may be due to the malts and hop extracts used in brewing the concoctions.
Results of this study suggest that having a dark ale with dinner may be a good alternative for those who have tired of wine. However, it’s important to note that when beer is consumed in excess, the harm incurred on the liver and other organs is likely to outweigh any potential health benefits.
