This Eye Color Is Linked to Alcoholism

Is it mere coincidence, or do people with blue eyes really run a higher risk of being alcoholics? A new study out of the University of Vermont suggests that the link not only exists, but it appears to be a genetic one.
Reporting in the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, the researchers find that among European-Americans, those with light-colored eyes — described as ones that are green, gray, and brown in the center — have higher rates of alcohol dependency than Euro-Americans with dark brown eyes; that link is strongest in blue-eyed people.
“We still don’t know the reason,” researcher Dawei Li says in a University of Vermont press release, but they do know that the very genes that determine eye color are situated along the same chromosome as genes that are known to be linked to alcohol dependency.
