I have recently discovered that any foods I eat with potassium give me migranes! I take rizatriptan when the migranes get bad but depending on what I have eaten that rarely shifts it, I've been looking in to what foods contain potassium and it seems that even foods that have a moderate or low level still affect me. Also a lot of medications contain potassium as the salt! I am now stuck on what to eat as almost everything seems to contain potassium, what foods can I eat that do not contain potassium? :confused:

Potatoes and bananas have lots of potassium do they give you headaches?
What are all the foods you have noticed that definitely give you headaches?
I am wondering if it could be something else in the foods.

Bananas is the reason I thought it was potassium, I used to eat a banana a day at work and for a few days I never had one and I realised that I never had a headache, also the week after I had naproxen tablets and penicillin tablets for tonsillitis and had really bad headaches with them also, when I looked into it the ingredient they all contained that was the same which was potassium, also when I eat oranges certain juice ,potatoes,and milk products like actimel drinks and yoghurts but I am not sure if they contain a high level of potassium.I did not have this problem when I was younger as I have always ate fruit and veg and also had tonsillitis quite a lot, for which I had to take penicillin tablets . I can't think of anything else it could be. Is there any other ingredients that could cause this?
