Your blue eyes may be charismatic, but recent study says they could make you turn to alcohol. Scientists conducted a research at the University of Vermont and they have concluded that people who possess baby blues could be in danger of becoming an alcoholic. The authors of the study discovered that people of European American ancestry who have light-colored eyes have a higher risk of alcohol dependency.
Eye Color Can Be Useful in Diagnosing Alcoholism
The study discovered that there is a connection between the genetic components that make up the eye color to the genes that relate to alcohol. The chief author of the study, Arvis Sulovari is a doctoral student and is an assistant professor who suggested that the research is helpful for clinics to know whether a patient’s problem is alcohol dependence or not.
More than 1,260 samples were present for the study and the researchers ultimately found the connection between alcoholism and eye color. They retested their investigation to make sure and they even included various parameters, such as location, sex, and age of the respondents.
Alcohol Dependence is Strongest in Blue-Eyed People
The report, which was published in the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, outlined that European-Americans who have light-colored eyes are more likely to be dependent on alcohol than those who have dark brown eyes. Light-colored eyes are those that are gray, brown, and green in the center. However, the strongest link is found in people with blue eyes.
Dawei Li, one of the researchers in the study, said that there is still no specific reason to the connection. However, they are convinced that the genes responsible for eye color are located in the same chromosome as the genes that determine alcoholism.
This is not the first time that alcohol and eye color have been linked with each other. In fact, in 2000, there was a study that had the same conclusion in which dark-eyed females consumed fewer drinks monthly than those who have light eye colors.
Having blue eyes also show a relationship to other attributes, such as higher competitiveness and lower tolerance to pain. According to Sulovari, this becomes an intriguing possibility that eye color may have a say in diagnosing some conditions, including alcohol dependence. The researchers are also convinced that the study can be useful for understanding the cause of psychiatric illness as well.
