I am a 60 plus year old woman who has suffered from Atrial Fibrillation for a number of years. I noticed after some time that it was triggering about 40 minutes after partaking in food and have spent many years trying to pinpoint the triggers. Sorbate preservatives 200 and 202, plus 282 are most definitely my triggers also alcohol which I have stopped drinking. I get triggered mainly by sauces and dressings or anything with those preservatives in.  I do wonder how many people are unaware that their Atrial Fibrillation is triggered by certain additives or food groups. It took me many years to pinpoint my triggers, and I now have to be very careful especially when dining out – Sandie
