Had 30 mins of erratic and fast heart beats (not strong) last night the first for a while,

checked my food intake again and discovered food additive No 621 was taken in the spring vegetable soup that I had, this caused me problems in chicken and leak with 621 twice before a few months ago. Has anyone had any problems with this food additive, appreciate your reply, thanks Ultramarine Australia

Can I know usually that additive used in which type of food ? Since I'm monitoring my food and noticed a link between the food trigger my migraine and irrythemia

My list including natural food such as grapes , banana , nuts , chocolate ,,

And other artificial such as some types of noodles , corn flacks , canned food , specific types of juices , smoked meat, ....


Hi Maitha, Chocolate is on my list, I can only have 2 small portions now or none atall. The food additive is on the side or back of any packet in the supermarket, along with other ingredients. My question to myself is always, do I use this a little or a lot?, if its a little then its something I avoid if its a lot and want to keep eating it, then I try to limit my intake. When you eat out there is no way of knowing though. I check ALL the ingredients plus the MSG component and so far only 621 is a problem! I also think the anxiety along with not knowing what to eat is part of the problem so I give myself a month or two to write these up properly.


I see food additive 621 is our old friend MSG, monosodium glutamate. Subtly added to a lot more foods that Chinese takeaways e.g. flavoured crisps. When I was learning about these things (the very hard way!!), coming home one night from the inlaws, we got a sweet and sour takeaway half way through our 100 mile journey. 30 minutes later, I had a severe attack of AF which ended up in the emergency room and an overnight stay in hospital.

I now have a quite long list of "no-no" foods which I know promote arrhythmias, and my sincere advice is to always read the ingredients list thoroughly. The foods that affect us can be a lot wider that caffeine, MSG and alcohol - I am affected by all cheese, and fermented products such as some brown sauces, miso, tofu, and most soy products. BUT your list could be different from mine - we are all individual and we often have to find out the way that you just have. I just wish that food effects were more recognised by the medics.

Take care - Chris H


I didn't know MSG could cause arrhythmias... I will bear that very much in mind! Thank you for the information, though I'm sorry you found out about it this way.


Thankyou for replying Chrisharmer and Eatsalottie, I am glad someone thinks its of some importance, because that's what happened when I gave up Coffee, I started with a food diary first as I wanted to know if this was connected, as I always felt out of sorts first before any episodes. Chinese food was one of the first things I took off my list, as the sauce ingredients were unknown to me. Then slowly I gathered more information, my theory is that it is connected to my digestive tract somehow, but I am not a physician. I do think this is part of the problem although not all. I do type up a list of my food theories and hand it to the GPs who might or might not look at it. Thanks again for your support Ultramarine Australia


Ultramarine, Being a quite serious cardiac patient, myself... Would hope you have, a physicians appointment soon. They can put a home monitor on you, do some stress tests, or even give you some meds, while at the clinic or hospital. It may not be just foods or MSG. Also, I am diabetic when my sugar gets out go wacky... I have had pain (like from running a distance ))and show all kinds of irregular or rapid rates.

Had stents put in a few times. Also ,had a treatment that is called a cardiac ablation that scars the section of the heart causing the irregular or rapid beats.

That's enough... Please be aware & take care! Hey we could make a bumper sticker out of that saying. Lol. Ozz & me.


Thankyou so much ozzymom I am due to see a Cardiologist after Christmas, its just I was going so well, on the meds that I am currently on I thought it could be something else. You would most likely know a lot more than me with what you have had to put up with. If this continues I will be asking to go earlier than this, at the moment its OK. I will be asking him about ..what comes next? this time, he is quite young and just out of college, he will do whatever I ask him though, so I'm learning all the time, and will ask about stress tests etc. Thanks again for your concern - good sense of humour - maybe ask admin to sponsor a T/shirt too.


I am no expert just been through a lot of things. Also have had a time dealing with some physicians who were not serious about their professions. If it does not seem right as to what their opinion may be.... then there is nothing wrong about getting another opinion.

Hope all goes well for you.


Does anyone have any evidence that food ingredients or additives increase the incidence of AF?

I can find plenty of evidence that caffeine doesn't trigger AF, and that omega 3 fish oil reduces the risk, but not much else. There's also some evidence that high alcohol consumption increases the incidence in men, and that vitamin C reduced the risk of post-operative AF in dogs. Lombardi et al have observed that there's an increased incidence of AF shortly after a meal of any kind though, which seems to me like a recipe for a lot of post hoc arguments.

Some relatives sent me a newspaper article claiming that tyramine is a trigger for AF, but I couldn't find any real evidence for it. Their case seemed to be based on just a single individual who had an episode after eating in a restaurant whilst on holiday. I couldn't find any databases of tyramine levels in foodstuffs either, so it wouldn't be very practical to attempt to reduce it.
