Last Supper to blame for our fattening culture.

From FOX News:

The food in famous paintings of the meal has grown by biblical proportions over the last millennium, researchers report in a medical journal Tuesday.

Using a computer, they compared the size of the food to the size of the heads in 52 paintings of Jesus Christ and his disciples at their final meal before his death.

If art imitates life, we're in trouble, the researchers conclude. The size of the main dish grew 69 percent; the size of the plate, 66 percent, and the bread, 23 percent, between the years 1000 and 2000.

Supersizing is considered a modern phenomenon, but "what we see recently may be just a more noticeable part of a very long trend," said Brian Wansink, a food behavior scientist at Cornell University.
