Researchers at Iowa State University and Cornell recently combined resources for a study that revealed that people who pour less wine drink less wine. It’s true. An Iowa State news release reports that the researchers asked 74 college students and staff to pour wine in a variety of settings so that they could control for the size, shape and color of the glass, as well as if wine is poured with a meal. They poured both red and white wine from bottles with different levels of fullness. Participants were told to pour as much as wine as they normally would in one setting. What did they find? That people who used a “rule of thumb,” such as a half-glass rule or a two-fingers-from-the-top rule when pouring wine, poured less regardless of BMI or gender. “About 70 percent of the people in the sample used the half-glass rule, and they poured significantly less by about 20 percent,” said lead author Laura Smarandescu. “It’s a big difference. We would suggest using a rule of thumb with pouring because it makes a big difference in how much people pour and prevents them from overdrinking.” The study, which looked at the amount consumed as well as the amount poured, found that “free pouring wine increases the tendency to over consume …” Thank you doctor.
