Earliest direct evidence of milk consumption

The evidence comes from dental plaque from Neolithic remains

Scientists have discovered the earliest direct evidence of milk consumption by humans.

The team identified milk protein entombed in calcified dental plaque (calculus) on the teeth of prehistoric farmers from Britain.

It shows that humans were consuming dairy products as early as 6,000 years ago - despite being lactose intolerant.

This could suggest they processed the raw milk into cheese, yoghurt or some other fermented product.

This would have reduced its lactose content, making it more palatable.

The team members scraped samples of plaque off the teeth, separated the different components within it and analysed them using mass spectrometry.

They detected a milk protein called beta-lactoglobulin (BLG) in the tartar of seven individuals spanning early to middle Neolithic times.
