For me personally
@jake45 I have a list but the same might not apply to anyone else. I am very intolerant of a lot of foods most people take for granted, like potatos and tomatos, high amine and high salicylate foods.
I keep a food diary which helps me decide on the basis of what causes a reaction and work out the theory later but there is always the possibility I have misunderstood.
Its hard to know what is good for others but I am normally safe on pork and beef cooked from fresh.
Chicken gives me brain hype and salmon and other fish typically give me a day of headache at the moment but didnt used to, however my food diary suggests this may be due to often eating lentils the day before the fish and headache so I will have to stop red lentils and try again, lentils have a reputation for causing migraines for some people.
Turkey I think depends a bit what it has been fed on. I react badly to soya and I suspect that there is soya in some turkey feed, sometimes turkey makes me feel the same way as eating soya, neuro-shakey and muscle wasting type muscular ache, but sometimes it does not. I think perhaps it is better if cooked for longer like a Christmas roast.
I read chicken hype was due to amines and they are concentrated in the skin but even avoiding skin is not enough. Its dose dependant and cumulative so I can get away with small amounts with long intervals of a week or so between which is good because I can eat chicken livers sometimes which is nutritious.
