Breaking bread -- lots of it

Last Supper helpings have grown

The Christian faith holds several acts of "super-sizing" to be miracles accomplished by Jesus Christ -- a handful of fish and loaves of bread expanded to feed thousands; a wedding feast running low on wine suddenly awash in the stuff. Now a new study of portion expansion puts Jesus once more at the center.

In a bid to uncover the roots of super-sized American fare, a pair of sibling scholars has turned to an unusual source: 52 artists' renderings of the New Testament's Last Supper.

"I think people assume that increased serving sizes, or 'portion distortion,' is a recent phenomenon," said Brian Wansink, director of the Cornell University Food and Brand Lab and author of "Mindless Eating: Why We Eat More Than We Think." "But this research indicates that it's a general trend for at least the last millennium."

Atsa lotsa motza.
