Whilst I understand that folks want a definite 'yes you can eat/no you can't' list, I have to say I'm taking a more relaxed approach to the whole thing second time round. I believe that it is up to you to find out information, risks, statistics etc and make your own mind up.
In general, I think if there is a chance something will make me ill (preggers or not preggers) I will give it a miss while pregnant. Eg seafood from somewhere I don't trust 100%, chicken on a BBQ, cheese so ripe it is about to crawl off. I am also avoiding pâté, liver and raw eggs. But I am having the odd small glass of wine, runny eggs, pasturised brie, pink meat (sadly a bit more cooked than my usual Rare preference) and the odd caffeine drink.
I think folks who say 'you can't eat X' should perhaps rephrase to 'the current NHS advice is to avoid X'. Because I personally don't find diktats like that helpful. By all means arm yourself with as much info as possible but don't judge others for what they have decided is a risk they are not overly concerned about.
Same way as I wouldn't judge folks for having had a few cigarettes. Not what I'd do, but I understand how hard it is to stop smoking and it's not really my business, is it?
