  Researchers from Monell Chemical Senses Center in Philadelphia are reporting that people with unexplained body odor issues may be suffering from a metabolic disorder, trimethylaminuria (TMAU) or “fish-odor syndrome”. TMAU is a genetically-transmitted disease that inhibits the ability of an enzyme to metabolize or transform trimethylamine (TMA) and is not based on lack of hygiene or personal care.

Yet once every week or two, he squeezes in time for a money-losing venture. For a nominal fee, he meets with people who have come to his Philadelphia lab from all...
