（张华医师听力师注：这是一篇有争议的文章，仅供专业人士参考。个人观点：1.饮酒有害健康，有损听力！ 2. 坚决不赞成听力不好的人士尝试！ 3.有益的提示是：我们寻找的灵丹妙药很有可能存在于日常的食物中，我国有专家多年前就尝试从缺铁的角度治疗耳聋）。

最新（2017年4月）研究显示，每天喝一品脱(568毫升，一斤多点)吉尼斯黑啤可以帮助你防止耳聋。长久以来被认为具有药用价值的吉尼斯黑啤，由于其含铁量高，也可以对抗听力损失。

在康复治疗过程中，吉尼斯黑啤通过补充铁元素增强病人的力量。而最新发表在《美国医学杂志》上的文章表明，这有助于患有听力障碍的病人。

似乎吉尼斯在醉酒时有一个有益的影响，提供急需的铁，可能有助于预防耳聋。《每日邮报》报导的标题是“不想失聪吗？每天喝一品脱吉尼斯黑啤。”

宾夕法尼亚州立大学的研究发现，高铁含量有助于阻止听力损失。这项对30多万人的研究发现缺铁性贫血（IDA）和听力损失之间存在联系。世界上超过30%的人口贫血，需要更多的铁，并且有听力丧失的危险。

宾夕法尼亚州立大学的研究人员发现，矿物质的缺乏会导致感音神经性听力丧失——耳蜗或神经通路受损。他们还发现，它还可能导致传导性听力损失——中耳的听小骨出现问题。

研究作者Kathleen Schieffer说：“成人的IDA和听力损失之间存在联系。

“接下来的步骤是更好地了解这种相关性，以及及时诊断和治疗IDA是否会对听力丧失的成人的整体健康状况产生积极影响。”

最近的研究表明，含铁药片对血管的DNA损伤没有帮助。在这种情况下，吉尼斯黑啤可能是一个完美的替代品。

人们常说吉尼斯有药用价值，尽管现在人们拒绝兜售。

它在20世纪20年代的广告口号是“吉尼斯黑啤对你有好处！”

有人声称吉尼斯黑啤可以有效地抗血栓，因为抗氧化化合物可以减缓危险胆固醇的积累。

这对于吉尼斯黑啤的爱好者（尤其是有点听力问题者）可能是一个好消息。

Guinness may help stop hearing loss

A pint of Guinness each day can help stop you going deaf, new research shows. Long thought to have medicinal properties, Guinness, thanks to its high iron content, may also combat hearing loss.

Up until recently, Guinness was given to patients in recovery to build up their strength and now, apparently, it replaces lost iron, which helps patients with hearing difficulties. The new research was published in the Journal of American Medicine.

It seems Guinness has a beneficial impact when drunk, providing much-needed iron that may help to prevent deafness. The Daily Mail first reported the link under the headline "Don't want to go deaf? Have a pint of Guinness every day."

The research at Pennsylvania State University found that high levels of iron help stop hearing loss. The study of more than 300,000 people found a link between iron deficiency anemia (IDA) and hearing loss. More than 30 percent of the world’s population is anemic and needs more iron and is in danger of hearing loss.

Pennsylvania State University researchers found a lack of the mineral can cause sensorineural hearing loss – damage to the cochlea or nerve pathways. They also discovered it could also cause conductive hearing loss – problems with the bones in the middle of the ear.

Study author Kathleen Schieffer said, “An association exists between IDA in adults and hearing loss.

“The next steps are to better understand this correlation and whether promptly diagnosing and treating IDA may positively affect the overall health status of adults with hearing loss.”

Iron tablets do not help, recent research showed, due to DNA damage to blood vessels. In that case, Guinness might be a perfectly good substitute.

Guinness is often said to have medicinal properties, although the company refuses to tout them in the modern era.

Its advertising slogan from the 1920s was “Guinness is good for you!”

It was claimed that Guinness was effective against blood clots because of antioxidant compounds which slow down the accumulation of dangerous cholesterol.

So, it could be a case of "hear, hear" for Guinness fans, especially those a little hard of hearing.
