Scientists find "millennial poop" and discover what Europeans ate 2,000 years ago
Scientists have found very old human feces in Austria, and through this they were able to identify some things that Europeans consumed approximately 2,700 years ago. The study, published in the scientific journal Current Biology, points out that this fossil species remained preserved in the region's prehistoric salt mines in the last millennia.

The analysis shows that Europeans ate blue cheese and drank beer during this period. To reach this conclusion, the group used a series of analytical techniques that allowed the identification of microbes, proteins and DNA present in the samples, and consequently the construction of a picture of the eating habits of this population and the composition of their intestinal bacteria.
The findings revealed a high-carbohydrate, high-fiber diet consisting largely of unprocessed bran and cereals, which were likely consumed in a kind of porridge. This staple food was supplemented with proteins obtained from broad beans, as well as with fruits, nuts and animal products.

The study authors also noted, when comparing old fecal samples with those produced recently, that "the modern industrialized human gut microbiome has diverged from an ancestral state, probably due to modern lifestyle, diet, or medical advances." The researchers extended their analysis to include fungi and detected high concentrations of species such as Penicillium roqueforti and Saccharomyces cerevisiae , which are used in cheese production (such as gorgonzola, for example) and in beer fermentation, respectively. The full study can be found in the journal Current Biology .
