Fecal odorgrams. A method for partial reconstruction of ancient and modern diets
Abstract:
Modern and ancient human feces (coprolites) and modern nonhuman animal fecal samples were subjected to headspace gas-chromatographic analysis for detection of odors related to dietary intake. The odors of grass, green leaves, licorice, meat, and corn were detected in coprolites dating to 6400 years BP (before present). Analysis of modern human samples revealed a large number of odors reflecting dietary constituents. The complexity and number of fecal dietary odors recovered was directly related to the number of food items ingested. Animal fecal odorgrams were characterized by a relatively large number of pleasant odors. Fecal odorgrams represent a new method by which modern and ancient diets may be partially reconstructed.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
