Researchers at the University of Zurich, examining dental calculus from ancient Peruvian individuals at the Wari Empire site of Cerro Chepén, have uncovered an unexpectedly diverse plant-based diet. Using advanced metagenomic analysis, the team identified DNA traces of over 20 different plant species, including maize, beans, squash, and various tubers and fruits. The methodology involved meticulously scraping calcified plaque from ancient teeth and extracting genetic material to pinpoint dietary components. This detailed insight into ancient eating habits suggests a sophisticated understanding of local flora and agricultural practices. The study, published in PLOS ONE in late 2022, provides a nuanced view of pre-Columbian nutrition.

Why It’s Fascinating
This discovery challenges previous assumptions that ancient Andean diets were heavily reliant on a few staple crops or animal proteins, showcasing a richer, more varied plant consumption. It matters beyond the lab by highlighting the nutritional wisdom of ancient populations and their sustainable use of local ecosystems. A concrete real-world application is inspiring modern dietary recommendations and agricultural diversity initiatives, promoting the reintroduction of forgotten nutrient-rich plant species within 5-10 years. It’s like finding a detailed recipe book from 1,000 years ago, revealing a vibrant and balanced menu. Nutritionists, ethnobotanists, and public health advocates can greatly benefit, understanding the resilience and health potential of diverse plant-based diets. Could ancient dietary patterns hold keys to addressing modern nutritional challenges?
