I've made a bunch of changes over time with the main one being less processed food - I was a bit junk food happy!
One that I believe I can feel making a big difference is the juice of a lemon with water, on an empty stomach first thing in the morning. I've perceived this has helped ease attacks when I've had them and so far seems to have helped keep them away. There's a little science that it's meant to help neutralise acids within the blood.
Cherries are meant to also help so I include these in smoothies (frozen).
I mostly stick to wholemeal bread, pasta and brown rice.
I do still eat lots of shellfish, oily fish and enjoy a beer but so far I've avoided a serious attack for a long while. I've not kept a diary but I think it has been 12 to 18 months now. If I do feet a twinge I cut back on seafood and will avoid alcohol but increase lemon in water and cherries.
