A few months ago I went to a seafood restaurant as a somebody's guest and had a wonderful platter of sea-foods soaked in olive oil. It was delicious - I can still taste it. Normally I wouldn't touch olive oil as so far as I know it contains salicylate but as I was a guest and this was an expensive meal I was too polite to refuse.
I had taken a Singulair but I was still surprised at how well the meal went down. Very few ill-effects and normally the more expensive the restaurant, the worse the effects.
Now I have an answer - because fish of course contains omega 3 while meat I think contains omega 6. So the meal was low in omega 6 even if it was not zero salicylate.
So I need more fish in the diet.
