According to a new study by Iowa State University and Cornell University, published in the International Journal of Drug Policy, sticking to a general rule of pouring just a half glass of wine at a time limits the likelihood of wine overconsumption.
The study team conducted an observational study that examined various factors that influence overpouring, and consequently the overconsumption of wine. They investigated how rules-of-thumb in pouring affect the quantities of alcohol poured by men and women across various BMI categories.
According to Laura Smarandescu, lead author and an assistant professor of marketing at Iowa State, "The use of the “half glass” rule-of-thumb in pouring reduced the volume of wine poured by over 20% for both men and women. Importantly, this rule-of-thumb substantially [reduced] the pours by men at high BMI levels."
Eye-balling a serving size is a difficult task which ofen leads people to pour too much. Using this simple “half glass” rule-of-thumb may be an effective way to curb overpouring and possibly overall overcomsumption.
So, next time you open a bottle of wine or have access to wine, serve yourself a half glass. Don't rush and enjoy every sip. And you might be less likely to accidentally drink too much.
