From Science Daily: Odorprints Like Fingerprints? Personal Odors Remain Distinguishable Regardless Of Diet.
Scientists from the Monell Center present behavioral and chemical findings to reveal that an individual’s underlying odor signature remains detectable even in the face of major dietary changes.

"This distinctive odor can be detected using either an animal’s nose or chemical instruments." [continue]
