In general Stone Age people consumed more protein and ate less carbohydrate than most humans do today, with fat intake probably about the same level; although this was a balanced blend of fatty acids (Omega-3: Omega-6) and relatively high levels of MUFA and PUFA, rather than today's focus on Omega-6, consequently Stone Age people were mainly free of the signs and symptoms of cardiovascular disease (CVD).Starch came from sources including grain, nuts and sea beet (the ancestor of beetroot and sugar beet) and evidence from Grotte des Pigeons cave in northern Morocco, indicates that extensive snacking on acorns and pine nuts may have led to some tooth decay. Analyses of the chemicals in Ötzi's hair suggests that meat may have made up between 10%-30% of the Iceman's diet.
Two days after the first discovery, Hans Kammerlander and Reinhold Messner, two famous mountain climbers from South Tyrol happened to arrive at the site, and the photo of figure 1 shows them watching the Iceman.
Messner made a first guess at the age of the man and thought he might have died some 500 years ago.
The discovery of the Iceman On 19 September 1991 an extraordinary archaeological discovery was made at a high-altitude mountain pass (Tisenjoch, 3210 m) of the Ötztal Alps near the Austrian-Italian border.
The Iceman was later nicknamed "Ötzi", after the mountain range where he was found.
This ridge forms the border between Austria (to the north) and Italy (to the south).
