Nausea: Since you're not pregnant, it appears that your vagus nerve is stimulated by the odor of certain food. This sets in motion a reaction in your gastrointestinal tract. You could take Dramamine to relieve the nausea. In your case you get nauseated rather than cramping or diarrhea. A gastroenterologist may be better to advise you about this symptom,however.
