Today's society has become accustomed to eating larger portions of food, an unusual new study has revealed.
Conducted by scientists from Cornell University, the research looked at 52 versions of the biblical 'Last Supper'.
The comparisons revealed that the food placed before Jesus and his disciples has grown in quantity by two-thirds.
Professor Brian Wansik, co-leader of the research, believes that this is a case of "art imitates life".
He added: "The last thousand years have witnessed dramatic increases in the production, availability, safety, abundance and affordability of food."
However, dietician Charlene Shoneye has warned of the uneven increase in portion size.
"Portions of fruit, veg and salad have not grown," she told the BBC.
"They should make up about a third of your plate, with the remaining two-thirds left for protein and starchy foods."
In another study from Princeton University, scientists found that certain sugars had a tendency to increase weight gain far more than others.
Rats fed fructose corn syrup, similar to the sugar found in fizzy pop, demonstrated a substantially higher level of obesity than the rats which were fed granulated sugar in the experiment.
