"In the new study, published in the journalProceedings of the Royal Society of London B , researchers analysed 100 archaeological samples from across England, as well as 14 samples from living dental patients and individuals who have recently died.
Dietary proteins were found in about one third of the analysed samples.
Proteins found in ancient dental plaque have already revealed that humans were drinking milk as far back as 6,500 BC."
