                                                          Irritable bowels are normally caused by a food sensitivity. Although sometimes viral infections can upset the bowels. Many foods can make bowels irritate, especially citrus or vinegar type foods. So if the salmon is marinated in a citrus type marinade or vinegar it could irritate your bowels. What foods irritate people can vary individually.
