Hey, there's so much useful info in this thread
Thanks Hilary - You know heaps and I can tell you're a research-geek like me

I'll check out the references you mention 'cos I really want to know more about all this. For instance, I think I might act as if histamine is the only problematic amine for me for now, to give myself more food options, and see how that works. I'm taking about 650mg magnesium at the moment, so hopefully any deficiency will be resolved soon.
Lisa, Thank you so much for you menu suggestions. Unfortunately, I am intolerant to gluten and dairy and have candida and blood sugar balance problems, so that limits a lot more foods

I'm still experimenting but butter and oats might be ok. Tolerated foods seem to vary so much for each of us. I am very glad to hear that the diet has helped you, it is very encouraging.
Pineapple - I do find candida a problem too but the anti-candida diet I've been on for the last 4 months is almost all high-histamine foods, so I'm floundering to know what to eat now. I take an anti-fungal and probiotic every day.
I think that, if I cook and eat breakfast and dinner at home, then a lunch that includes a high-histamine food like tinned fish or deli meat might be the best I can manage at the moment, and it has to be better than eating high-histamine foods at every meal, as I had been doing. I do want to feel better though. Does anyone know of any 'portable' protein foods that would make a good lunch? How do nuts and seeds effect others? Sunflower seeds seem to have a greater effect on me than tinned fish (I judge it by my post-meal facial flushing).
