It was so hot and delicious-looking, so fragrant. I took the store brand (made who knows where) Chicken Pot Pie home and ate the whole thing. Within ten minutes of starting to eat my heart rate was 156.
I chewed an aspirin and an atenolol, did some Valsalva maneuvers, and the rate came down to the 130's after a while. Then I read the ingredient list, tiny print, stopped counting at 85 items, chicken skins? There it was: Sodium bisulfite. If a sulfite is listed it's probably over 100ppm, which is a lot!
It took me a couple of hours to get the heart rate to normal and for the chest pain to subside to a tolerable level. I was exhausted the rest of the day and evening - an expected reaction to a long tachycardia episode.
There were a lot of other ingredients which are known to have sulfites, modified starch, carmel coloring, and "dough conditioner" which can be a name for more sulfites. There were also two other preservatives, so I don't know why they had to put in the NaHSO3.
