HI, I've been testing and evaluating triggers and diets for the past 10 years or so for CH.
I think I 've found new major triggers for me that may help others.
I can say that multivitamin supplements and some other minerals and vitamins were triggers.
Also any food from a can like a soup,
And with 100% certainty ,when in cycle any food bought from a restaurant or a dinner gives me CH
Past 20 days I tested 15 days with home cooking and 6 dinners from the outside.
Every time I had dinner from a restaurant I triggered a CH
With home made meals I was getting a CH only every 3-4 days.
even today stupid me ,ordered pizza,,,ch followed in 5min,,,
I also take only VitD,MG,Omega,,,I think some vitamins in VitD reg, were causing a trigger too, I'm not sure which one yet.
