A new research has claimed that consuming cheese had a significant effect on the shape of human skulls.
According to the study, the effect of agriculture on skull morphology was greatest in populations consuming the softest food – cheese.
David Katz, postdoctoral researcher at the University of Calgary said,"At least in early farmers, milk did not make for bigger, stronger skull bones."
Katz, with Professor Tim Weaver and statistician Mark Grote from University of California-Davis used a worldwide collection of 559 crania and 534 lower jaws (skull bones) from more than two dozen pre-industrial populations to model the influence of diet on the shape, form, and size of the human skull during the transition to agriculture.
They found modest changes in skull morphology for groups that consumed cereals, dairy, or both cereals and dairy.
"The main differences between forager and farmer skulls are where we would expect to find them, and change in ways we might expect them to, if chewing demands decreased in farming groups," said Katz.
As per the study, the largest changes in skull morphology were observed in groups consuming dairy products.
Katz said, differences due to diet tended to be small compared to other factors, such as the difference between males and females or between individuals with the same diet from different populations.
The finding was published in the journal Proceedings of the National Academy of Sciences.
