An article on Smithsonian.com by Jason Daley - Ötzi the Iceman's Last Meal Included Goat Bacon - reports on the analysis of the 5,300-year-old mummy's stomach contents which shows that Ötzi the Iceman ate dry-cured meat from a mountain ibex.

Since his 5,300-year old mummified body was discovered in the Ötztal Alps between Italy and Austria in 1991, Ötzi the Iceman has been studied in great detail; he was between 40 and 50 when he died, he was murdered by an arrow (although we do not know the motive), and he had calcification in his arteries. Researchers know what he wore and what his voice may have sounded like. In 2011 further research (poor fellow) of his stomach contents revealed a final meal consisting of cooked grain and meat from an ibex, a type of wild goat.

Now, however, researchers have refined the analysis; not just goat meat but goat bacon. Albert Zink, a mummy specialist from the European Academy of Bolzano analyzed the goat meat found in Ötzi's stomach. Looking at the nanostructure of the proteins, he was able to determine that the meat had never been cooked. Instead, it was dry-cured, making it into a product similar to prosciutto. It seems the Iceman travelled with cured meat. 

Whilst there, Zink discovered the oldest known Helicobacter pylori bacterium in the ice man, the pathogen that has been linked to the development of ulcers and gastric cancer. Ötzi had a particularly virulent strain of the bacteria, causing a reaction to the bug, leading him with ulcers or stomach problems.

The H. pylori also helps researchers track migration of people into and out of Europe. The fact that Ötzi had a strain that Europeans share with Asian populations and not the North African strain most people have today means the populations probably had not mixed yet significantly.

Final meal: roughly an hour later - because otherwise his stomach would have emptied - he was shot from behind with an arrow.
