People living during the Harappan civilisation around 4,000 years ago, have been found consuming high-protein, multigrain 'laddoos', according to a study. Scientific study of the material found during an excavation in Rajasthan has revealed this. At least seven 'laddoos' were discovered in 2017 during excavation of a Harappan archaeological site in Binjor in western Rajasthan.
