WORKED TEMPORARILY
In the long run I have found just 2 things that make a major difference for me: I have to completely avoid eating chicken eggs, and likewise no cows' milk or cheese, no lactose. Duck eggs seem to be fine. Goat milk seems to be fine. Whey from cow milk I think is ok. Butter is fine. With this approach the polyps have shrunk quite a bit. I breathe partly through my nose at long last once again, and my sense of smell is back! I found which foods to avoid by trying periods of time avoiding them and then not, repeatedly. Incidentally, the lactose in an enzyme supplement not only made my sinuses worse, but gave me a headache and general aches and pains too, along with bad dreams, negative thoughts, and irritability.
Best of luck to you all, keep trying, find your triggers and avoid them and you can and will get much better.
