In 1991, German tourists discovered, in the Eastern Italian Alps, a human body that was later determined to be the oldest naturally preserved ice mummy, known as Otzi or the Iceman. Now, researchers reporting in the journal Current Biology on July 12 who have conducted the first in-depth analysis of the Iceman's stomach contents offer a rare glimpse of our ancestor's ancient dietary habits. Among other things, their findings show that the Iceman's last meal was heavy on the fat.

The findings offer important insights into the nutritional habits of European individuals, going back more than 5,000 years to the Copper Age. They also offer clues as to how our ancient ancestors handled food preparation.

Multi-omics - Approach - Microscopy - Iceman - Meal

"By using a complementary multi-omics approach combined with microscopy, we reconstructed the Iceman's last meal, showing that he has had a remarkably high proportion of fat in his diet, supplemented with wild meat from ibex and red deer, cereals from einkorn, and with traces of toxic bracken," says Frank Maixner of the Eurac Research Institute for Mummy Studies in Bolzano, Italy. Bracken is a genus of large ferns.

Maixner and colleagues, including Albert Zink, explains that the analysis hadn't happened earlier because scientists were initially unable to identify the Iceman's stomach. That's because it had moved up during the mummification process. In 2009, his stomach was spotted during a re-investigation of CT scans, and an effort to analyze its contents was launched.

Stomach - Material - Intestine - Samples - Amounts

"The stomach material was, compared to previously analyzed lower intestine samples, extraordinarily well preserved, and it also contained large amounts of unique biomolecules such as lipids, which opened new methodological opportunities to address our questions about Otzi's diet," Maixner says.
