Teeth are one source of evidence for food preferences [see previous course/post], but how can you be sure that what is found in the mouth is actually swallowed into the digestive tract proper? Arguably better is the contents of the stomach. That is the source examined by Frank Maixner et al., for Γtzi, the individual exhumed from an Alpine glacier in 1991 where he had lain apparently undisturbed for approx. 5,300 years.
Yet another βpost-mortemβ analysis [how many such indignities must one human being suffer?], this time of the contents of the recently-located stomach of the βicemanβ *, revealed a high-fat, high-calorie βmealβ. Although this was a balanced diet of at least three of the five major food groups β fat from Alpine ibex (Capra ibex), meat from red deer (Cervus elaphus; βproteinβ), and einkorn (Triticum monococum βcarbohydratesβ) β the fat content, at 50% of the meal, is extremely high. However, this is probably justified on the grounds that fat can help to give the additional calorie boost needed to an individual trying to keep warm in such hostile and very cold conditions. But, the most curious aspect of the stomach contents is the presence of bracken [Pteridium aquilinum], as an βabundance of spores and sporangiaβ.
Although widely eaten nowadays by many people β e.g. in China β it contains a potent cancer-causing compound, ptaquiloside. Itβs been suggested that bracken fronds may have wrapped some of the other foodstuffs and its spores were ingested accidentally. But, since bracken is deliberately consumed by humans today, it is possible β i.e. not inconceivable β that it was an intentional part of Γtziβs ancient diet. Weβll probably never know for sure, but, as Maixner et al. proudly conclude, βdetection of the Icemanβs stomach content with its pristine yet undigested food mix, provides the unique opportunity to fully reconstruct a Copper Age [or Chalcolithic Period from 4500 to 3500 BC] mealβ. But, since, and acknowledgedly, these are the contents of the stomach, how can we know for certain what would have been digested and assimilated and thus contributed to the Icemanβs growth and development? More mysteries to solveβ¦
* In an art-imitating-life kind of way, the 2017 film βDer Mann aus dem Eisβ [Iceman] purports to be a βbiographyβ of Γtzi (although neither knowingly authorised nor approved by Γtziβs heirsβ¦), in particular the events leading up to his death in the European Alps. Curiously, as a tale of bloody revenge featuring frozen landscapes, it has similarities with another film of the same English name. That 2012 film β about assassin Richard KuklinskiΒ [nicknamed βthe icemanβ] β is also a βchillingβ tale of cold-blooded murder but in the USA, and brings a new meaning to the phrase “revenge is a dish best served cold“/”cold vengeance”β¦
