Health on Freedom Plaza

This article examines another myth. Do you really have to go deaf as you get older?
New research strongly suggests that hearing loss could be preventable by eating an antioxidant rich diet or by taking antioxidant supplements.
According to the National Health Survey Hearing loss affects, for example, more than 40% of people in the US over the age of 65 and is the most common sensory disorder among older people. It is expected to be a problem for at least 28 million older Americans by 2030. This all sounds pretty grim and certainly the statistics seem to say that hearing loss and old age are inexorably linked.
Well, no it isn’t. At least this is what is strongly suggested by findings recently published online in theProceedings of the National Academy of Sciences.
The evidence suggests that antioxidants protect us against hearing loss.
Researchers in the University of Florida (UF), and scientists from the University of Wisconsin and several other institutions, have identified a protein that appears to be responsible for oxidative damage to cells that results in hearing loss.
We already know that the ravages of oxidative damage can be protected against or repaired using antioxidant therapies or by making foods rich in antioxidants a central plank of your diet. This then opens the door to potentially preventing or even treating hearing decline as we grow older.
Free radicals cause the cellular equivalent of rusting and this oxidative damage harms the mitochondria, the energy centers of cells. When this damage is continual and prolonged, the mitochondria malfunction and release proteins that cause cells to die. This process brings about a host of degenerative physical effects that are associated with aging -- including hearing loss.
In addition, the scientists discovered that in animals with excess amounts of an enzyme that scavenges free radicals, and in animals that were fed antioxidants , the onset of age-related hearing loss was significantly delayed.
"This paper clearly shows us that oxidative stress causes hearing loss," said one University of Florida postdoctoral fellow, in a statement to the media.
The moral of this story is, if you are getting on a bit and want to keep your hearing, as well other advantages of good health, make sure your diet is rich in antioxidants.
The Klamath lake wild blue-green algae is rich in antioxidants and so is green tea so make these part of your daily routine. You can pick up a free book on both these rich sources of anti-oxidants - see our home page.
