No, it’s not a joke or a sales pitch: according to a very serious study, a daily pint of Guinness prevents deafness! This may be explained by the high iron content of Irish beer, which is thought to help preserve hearing! Consumed in moderation, the Emerald Isle’s most famous Irish beer is a serious health booster! But
It’s not the first time Guinness has been credited with medicinal properties. Many Irish people have been claiming for years that the national stout is even the secret to long life! For many, Guinness is also said to have effective anti-clotting properties, thanks to its antioxidant compounds and anti-cholesterol effect. All the more reason to speculate about the benefits of Ireland’s number 1 beer!
Although the Irish brewery has never communicated on these hypothetically beneficial elements (this would pose legal problems, as Guinness remains first and foremost an alcoholic beverage, the consumption of which is governed by law), numerous researchers have attempted to demonstrate its health benefits.
And the hearing study focused heavily on Irish dark beer! Published in the Journal of American Medicine, it seems to establish a link between the high iron content of beer and its benefits in preventing deafness.
More specifically, the research was carried out at Pennsylvania State University in the United States. They found that high levels of iron helped prevent hearing loss. The study was carried out on a panel of over 300,000 people, and concluded that the more iron deficient a person was, the greater their risk of developing deafness.
The researcher in charge of the study, Kathleen Schieffer, said:
There is a clear causal link between iron deficiency in adults and hearing loss.
She pointed out, however, that iron supplements are ineffective, as they cause long-term damage to blood vessels. That’s why Guinness would be an excellent alternative, in her opinion.
Initial conclusions that need to be taken further. But let’s be reasonable. Don’t take this argument literally to increase your Guinness consumption: we saw you coming a mile away!
