There are a multitude of ways to prevent hearing loss and help reduce the risk of
noise related hearing damage, but did you ever think about the benefits of a glass of red
wine? There is some evidence linking red wine to a decrease in hearing loss after
exposure to loud noise.
In a study reported in Otolaryngology-Head and Neck Surgery, researchers from
the Henry Ford Hospital in Detroit found that red wine (and red grapes in general)
contained resveratrol. This substance has been shown to contain anti-inflammatory
characteristics and therefore may provide protection against hearing loss and cognitive
decline. In the experiment, researchers discovered that rats who consumed resveratrol
before being exposed to extended periods of loud noise would suffer less from long-
term effects of noise-induced hearing loss.
The lead author of the study and director of the Division of Otologic/Neurotologic
Surgery in the Department of Otolaryngology-Head & Neck Surgery Michael D.
Seidman said, “Our latest study focuses on resveratrol and its effect on bioinflammation,
the body’s response to injury and something that is believed to be the cause of many
health problems including Alzheimer’s disease, cancer, aging and hearing loss.” The
key to the study was understanding how exactly the resveratrol was able to protect the
ears from loud noise.
In their research, the scientists were attempting to “identify the potential
protective mechanism of resveratrol following noise exposure by measuring its effect on
cyclooxygenase-2 (or COX-2, key to the inflammatory process) protein expression and
formation of reactive oxygen species, which plays an important role in cell signaling and
homeostasis.” When exposed to loud noises the rats had an up-regulation of the COX-2
protein after a period of time. The resveratrol was able to reduce the reactive oxygen
species formation and inhibit COX-2 expression.
It might sound like a lot of scientific jargon, but in the end Dr. Seidman said they
were able to show “that by giving animals resveratrol, [they] can reduce the amount of
hearing and cognitive decline.” They showed the importance of resveratrol, which is
found in red wine but is also present in many other items including blueberries, peanuts
and other types of plants. So have a glass of wine, eat some red grapes or enjoy some
blueberries because the resveratrol that can be found in these delicious indulgences
may be able to help your hearing!
