Minimizing Your Calorie Intake May Delay Hearing Loss

Jun 9, 2011 by

The dreaded conversation on calories just got a little bit more interesting. Most of us have been on a diet where we restricted our calorie intake to lose weight, new research is showing that you may be able to more than just lose weight. Researchers at the University of Wisconsin-Madison found that restricting calorie intake may delay age-related hearing loss.

Researchers at the University of Wisconsin-Madison worked with mice to successfully delay age related hearing loss when they restricted their calorie intake. The mice had their calories restricted by 25% which resulted in the activation of an enzyme known as Sirt3. This relationship between the reduction in calories and Sirt3 resulted in the preservation of hearing. The hope is that by studying how exactly Sirt3 is activated, eventually they will be able to preserve hearing without reducing calorie intake. The research shows that when calories are restricted the organism feels it is under stress; therefore metabolic changed happen help with self-preservation. Restricting calories seems to boost levels of Sirt3, which helps the cells mitochondria. The mitochondria produce energy and free radicals. The free radicals, are harmful, and speed up the process of hearing loss. As Sirt3 levels rise, they stop the production of free radicals, therefore helping preserve hearing.

With more research about caloric restrictions and hearing loss hopefully people can start using this information to help with hearing loss prevention. People might actually be able to do this with something that mimics caloric restriction without actually having to suffer by always counting calories.
