    Blue eyes linked to alcoholism

    Burlington, VT—Researchers from the University of Vermont have say that people with blue eyes have a higher chance of becoming alcoholics, according to a study published in the American Journal of Medical Genetics: Neuropsychiatric Genetics (Part B).

    The researchers found that primarily European Americans with light-colored eyes—including green, grey, and light brown—had a higher incidence of alcohol dependency than people with dark brown eyes. The strongest tendency toward alcohol dependency was found among blue-eyed individuals.

    So, what’s the connection? According to the study, the genetic components that determine eye color line up among the same chromosome as the genes related to excessive alcohol use. But the study’s co-author Dawei Li, PhD, assistant professor of microbiology and molecular genetics, says the researchers still don’t know the reason why eye color is connected to alcohol abuse.

      This is an interesting correlation apparently appropriate for Euro-Anglo Americans. Alcoholism rates amongst Native American peoples, who are not known for blue irises,cannot be accounted for by this finding or perhaps even by this mechanism. My blue eyed, Irish, German, Welsh precedents account for alcoholism as being caused by drinking. In their somewhat glazed over eyes, there is rarely a case of too much or too often.
