Is Guinness good for your hearing? The popular beverage contains high levels of iron, which scientists believe helps to ward off hearing loss.
Not only can excessive alcohol use can lead to the development of chronic diseases such as high blood pressure, heart disease and stroke, but it can also increase the chances of developing hearing loss. To find out more on the effects read on.
A study at Pennsylvania State University has discovered a link between iron deficiency anemia (IDA) and hearing loss. Guess what famous stout is rich in iron? Yes, you heard it here, Guinness.
The Pennsylvania State University study found that lack of iron can affect your hearing which could cause damage to the cochlea and issues with bones in the middle ear. An iron deficiency leads to fewer red blood cells in the body. But iron tablets that are often taken to help combat IDA have been shown to potentially be harmful, as they contain too much iron for the body to handle in one go.
The research was conducted on more than 300,000 people. Statistics show that more than 30% of the world's population suffers from anemia and therefore may be in danger of hearing loss.
Around 1.6% of participants were found to have either conductive, sensorineural hearing loss and deafness. While 0.7% were believed to have IDA. They found a significant association between the condition and sensorineural hearing loss - which was present in 1.1% of sufferers. The conductive hearing loss was present in 3.4 per cent of those with conductive hearing loss.
Although Guinness contains a fair amount of iron, a pint only has around 3% of what the body requires on a daily basis. However, drinking 33 pints a day is not a solution.
It is believed antioxidant compounds in the drink, similar to those found in certain fruits and vegetables, are responsible for the health benefits because they slow down the deposit of harmful cholesterol on the artery walls. This beverage may be good for your hearing health but make sure you drink in moderation and don't over do it. There is a flip side!
Excessive drinking can damage the auditory cortex in the brain, therefore affecting the way your brain processes sound. The auditory nerve transfers the auditory information from the sounds we hear in the cochlea of the inner ear to the brain where they are then translated. Even though the ears may seem to be functioning properly, the brain may be unable to correctly process the sounds.
