Sri Lanka's ancient diets show early plant reliance predating agriculture by millennia

The shift toward plant-based diets in Sri Lanka reflects broader patterns of human adaptation to tropical environments during the late Pleistocene. Similar dietary transitions have been observed in other regions, such as the Amazon and Southeast Asia, suggesting a global trend toward diversification of food sources in response to climate variability.
The study on Sri Lankan diets reveals that plant-based consumption was not a byproduct of agriculture but a sophisticated and enduring strategy for human survival in tropical environments.
By integrating Indigenous knowledge, cross-cultural perspectives, and scientific methods, we can better understand the diversity and resilience of pre-agricultural societies. The findings challenge the Western-centric narrative that equates agriculture with progress and highlight the need to re-evaluate the role of foraging and plant-based diets in shaping human history. This synthesis underscores the importance of interdisciplinary approaches in reconstructing the past and informing sustainable food systems for the future.
