This study found a link with coffee consumption and lower rates of tinnitus, so perhaps coffee drinking would help those with tinnitus? Stay tuned. From Science Daily:
Caffeine intake associated with lower incidence of tinnitus
Higher caffeine intake is associated with lower rates of tinnitus, often described as a ringing or buzzing sound in the ear when there is no outside source of the sounds, in younger and middle-aged women. "We observed a significant inverse association between caffeine intake and the incidence of tinnitus among (participating) women," said the lead author.
Specifically, researchers report that when compared with women with caffeine intake less than 150 milligrams/day (approximately one and a half 8-ounce cups of coffee), the incidence of reported tinnitus was 15 percent lower among those women who consumed 450 to 599 mg/day of caffeine. The majority of caffeine consumed among the women was from coffee and the results did not vary by age.
"The reason behind this observed association is unclear," said Curhan. "We know that caffeine stimulates the central nervous system, and previous research has demonstrated that caffeine has a direct effect on the inner ear in both bench science and animal studies. Researchers note that further evidence is needed to make any recommendations about whether the addition of caffeine would improve tinnitus symptoms.
