Whenever I eat tinned fish I have such a bad reaction to it - it doesn't matter whether its sardines, mackerel, pilchards etc. I can eat these fish fine if I get them fresh, but I can't seem to eat tinned fish at all.
The reaction I get is that my breathing gets really really bad that night and for a bit the next day. I am being investigated for breathing problems anyway.
What is in tinned fish that causes such a problem for me? When I look on the ingredients list all it says is mackerel, oil/brine/water etc.
Can anyone help?
