I think this is very true. I did do a Elimination Diet a month ago where i only ate organic chicken with salad, low gluten, less fruit (sugar) and drank Celery juices and i notice i was able to smell again, as though the inflamation in my nose went down. I've had issues with being able to smell and that was the first time i could actually start to smell around me. I stopped because i wanted to take the food allergy test and its recommended you have a regular diet to do the testing or else it wont help. A change in diet/food and trying elimination is a great idea. Thanks for the information.
