The people of the Indus Valley civilization who lived in what is now northwest India 4,000 years ago had a diet high in meat, new research shows.
Analysis of pottery from the period reveals a preponderance of products of animal origin, including pork, bovine, buffalo and goat meat, as well as dairy products.
Scientists claim that people in rural and urban areas had similar diets, which allowed them to endure episodes of severe aridity caused by climate change.

Lipids have been discovered in ancient jars (pictured) and their concentration has long been used to paint a picture of the diet of ancient civilizations
Molecules called lipids, which make up fats and oils, are tough and traces can survive for millennia, while other nutrients, such as protein, degrade beyond detection.
Lipids have been discovered in the jars and their concentration has long been used to paint a picture of the diet of ancient civilizations.
Study author Dr Akshyeta Suryanarayan, a former PhD student at Cambridge University, said: “ The study of lipid residues involves the extraction and identification of the fats and oils that have been absorbed in old ceramic vessels when used in the past.
“Lipids are relatively less prone to degradation and have been found in pottery from archaeological contexts around the world.
“However, they saw very limited research on ancient ceramics from South Asia.
This study is the first to investigate the lipid residues absorbed in pottery from several sites in the Indus, including the Indus [capital] Rakhigarhi city, say researchers
“This study is the first to study the lipid residues absorbed in pottery from several sites in the Indus.
The research, published today in the Journal of Archaeological Science, looked at ancient ceramic vessels from rural and urban settlements of the Indus Civilization in northwest India, the Current states of Haryana and Uttar Pradesh.
The researchers say their study made it possible to “make comparisons between institutions and over time.”
Indus society spanned from 5,300 to 3,300 years ago, when civilization entered a period of decline and died out soon after.
What caused the demise of this once great civilization is a long-standing mystery.
A recent study claims that the Indus Valley civilization has been wiped out by climate change.
He claims that the monsoons increased about 5,250 years ago when the planet cooled, which allowed the Indus civilization to emerge and thrive as storms provided water to the semi-arid region via the Ghaggar – Hakra river system.
But a climate change 2000 years later saw the number of monsoons drop, reducing the amount of water on which Indus settlements along the river system and depended.
When it dried up, society collapsed into oblivion.
The society existed at the same time as ancient Egypt, but much less is known about the Indus people due to the few surviving artifacts.
By identifying the presence of lipids and analyzing them to determine their origin, researchers have better understood the typical Indus diets.
Dr Suryanarayan says the study faces difficulties in interpreting the results because it generated unexpected results.
“For example, we found a predominance of non-ruminant animal fat, although animal remains like pigs are not found in large quantities in the Indus colonies.
“It is possible that plant products or mixtures of plant and animal products were also used in vessels, creating ambiguous results.”
Additionally, despite the high percentages of domestic ruminant remains found at these sites, there is very limited direct evidence for the use of dairy products in containers, including in perforated containers that have previously been suggested to be related to dairy processing. ‘
