What specific chemical component in oilfish is responsible for causing digestive distress?

Answer

Wax esters

The significant gastrointestinal distress associated with consuming oilfish or escolar is directly caused by the presence of high concentrations of wax esters in their flesh. Wax esters are a unique type of fat composition specific to these species. Crucially, the human body lacks the necessary enzymatic machinery required to properly break down or digest these long-chain fatty acid esters. Consequently, when consumed in sufficient amounts, these undigested waxes travel through the system, irritating the intestines and producing the severe laxative effect characterized by diarrhea, cramps, and nausea. While beneficial fish are celebrated for healthy fats, the wax esters in oilfish are problematic because they remain unaltered during digestion.
