Researchers (and brothers) Brian and Craig Wansink have examined 52 of the most famous images of the Last Supper -- where Jesus and his disciples observed a Passover seder, the last before the Crucifixion -- and found a sizable increase in portions over the past millennium, from the year 1000 to ten years ago.
Brian Wansink told the LA Times, "I think people assume that increased serving sizes, or 'portion distortion,' is a recent phenomenon. But this research indicates that it's a general trend for at least the last millennium." Wansink, who authored Mindless Eating: Why We Eat More Than We Think, and who has conducted many portion-size studies as director of the Food and Brand Lab at Cornell University, brought his years of nutrition research to the study. Meanwhile, his brother Craig, a biblical scholar at Virginia Wesleyan College, brought the religious studies chops to their analysis of what they are calling "history's most famous dinner party."
