A Healthy Balanced Diet Helps to Protect Your Hearing
The link between diet and hearing is becoming stronger.
Studies from Florida University found that a balanced diet can protect the ears against the harmful effects of loud noise exposure.
The researchers analysed the diet of 2,366 people who responded to a survey regarding health and underwent hearing tests. The results showed a strong correlation between diet and hearing.
The hearing thresholds of those who maintained a well-balanced diet but had significant exposure to loud noises were comparable to those who had a poor diet and no noise exposure.
According to this research which was published in the International Journal of Audiology, a healthy diet includes regular consumption of vegetables, fruit and fibres with low intake of salt and saturated fats.
Hearing Health Relates to General Health
Our hearing health is linked to our general health. The auditory system depends on the good function of the cardiovascular, neurological and metabolic systems. If our general health is impaired the organ of hearing will be more vulnerable to injuries that may cause a permanent hearing loss, or conditions such as http://www.healthyhearing.com.au/hearing-loss-in-menieres-disease/Meniere’s Disease with Hearing Loss.
A hearing loss may be caused by a variety of factors and some of them may not be avoidable such as genetics and age. In addition to diet and hearing health, other factors such as cardiovascular health, intake of ototoxic drugs, exposure to chemicals and loud noises can be controlled to avoid loss of hearing.
According to the American study, the relationship between a good diet and better hearing in the higher frequencies was statistically significant. A good diet may not reverse an established hearing loss but can help to prevent further deterioration.
Diet and Hearing: Omega 3 – Fish Oil May Reduce Risk of Hearing Loss
Acquired hearing loss is a chronic health condition of high prevalence in our society. Although a loss of hearing is mostly considered as an unavoidable characteristic of the ageing process, identification of several risk factors has brought a new understanding of the possibilities of preventing and delaying acquired hearing losses. There is some evidence that Omega 3 from fish (fish oil) is associated with a diminished risk of hearing loss.
Researchers from Brigham and Women’s Hospital in Boston found that fish consumption is associated with a lesser risk of hearing loss in women. Their study analysed the correlations of specific fish consumption and hearing health in females.
Compared to those women who rarely ate fish, those who had two or more portions of fish a week had a 20% less risk of losing hearing.
Lack of potassium has been found to adversely affect hearing. This mineral is responsible to promote nerve impulse transmissions so that potassium-rich foods such as banana, melon, orange, spinach and beans are highly recommended to promote hearing health.
Foods rich in C and E vitamins such as lemons, orange, almond and avocados also promote hearing health by improving blood circulation and boosting the immune system, preventing infections which may affect the ears.
On the other hand, high consumption of sugars and carbohydrates have harmful effects on the hearing system and should be avoided to prevent hearing loss.
