The growing size reflects the success of agriculture over the ages, the researchers said.

　　研究人员称，食物和餐盘尺寸的增长反映出这么多年来农业产量的增加。

　　"The last thousand years have witnessed dramatic increases in the production, availability, safety, abundance and affordability of food," said Brian Wansink, a professor of marketing and applied economics at Cornell University.

　　康奈尔大学营销和应用经济学教授布赖恩·万辛克说：“在过去一千年间，食物的生产、可用性、安全性、丰富程度以及可购性都大幅提高。”

　　"We think that as art imitates life, these changes have been reflected in paintings of history's most famous dinner."

　　“我们认为，由于艺术描绘的是现实生活，所以这些变化也反映在这一史上最著名的晚餐的画作之中。”
