Heart spasm caused by?

When I get into anything with sulfur in it, I suffer a heart spasm.    I do not understand why this is.

I had a heart attack in 2000 and was found to have totally clean arteries.  At that time I was having upwards of 25 -50+++ heart spasms a day and was under a wrong diagnosis of esophagael spasm.  

I figured out that it was sulfites and sulfur that I was sensitive to so I quit eating all packaged, processed and canned foods.  I began eating raw nuts and sunflower seeds and lots of fruits and veggies.  My spasms ceased.  I have now only had very severe ones a few times, related to food intake.  I do not understand why the sulfur causes me to spasm.  

My one daughter also gets them from sulfur ingestion in even small amounts.  I read that there is something about the absence of something called molybdendum or ? and I think I might have replaced some of that in my intake of all the sunflower seeds and nuts.   Can you help me?  I need to know why my body can't process sulfur. I even had a reaction to Detalizam as there is a covered molecule in it.  I had a severe heart spasm after 4 small dose pills.  The cardiologist and the GP doc and 3 pharmacists swore that there was no sulfur in it, but there is.  One of them found it for me, as I was certain that was what caused it.  I know I have misspelled some words here, please forgive.

Is there a suppliment I can take?  I have read that this molydbendum however you spell that, can be taken and that it might be what causes the inability to process the sulfur.  I talked to a guy, not a doctor as the doctors don't seem to understand chemisty well, but this fellow says that that the sulfur ? releases sulfur dioxide I think it was and that is what my body can't handle.  

I am also allergic to the asulfamine K in many foods and I find eating to be a walk into the valley of death sometimes, and ended up in hospital with eating out a few times.  The asulfamine K is also a trigger for me for spasms.   Can you point me in a direction of treatment or how to get help from a doctor?  Thank you.  Dash4

I don't know if you ever heard of Compound Pharmacies.  But if you can find one in your area or one that ships, they make up your medication without the bad additives in it.  That might be a way to handle the medication problem.  I am considering if I need to do this myself.  I used to get spasms from eating wheat and preservatives.  Preservative are usually sulfites anyway and they do put them in medications to keep a shelf life.  I suspect you might want to try to get your body 100% off of these sulfites for a long time.  Your body will be less sensitive.  I have been off them the best I can for a year.  I drank a can of soda without major distress like before.  But do know I have a long time to go yet.
