Yes, but it is very easy to say 'Oh my mum ate that, and I was fine', but we have more knowledge now than then. When my mum was pg with me, they did not have scans, but that does not mean that I will not take advantage of the increase in knowledge and technology around now!
I doubt very much if my parents ate much goats cheese, pate and rare steak, as those foods were not so common and available as they are now. OK, so I know that I am generalising, but I know that I would have never have forgiven myself if I had done eaten anything that had subsequently caused my baby to miscarry. I have heard of a woman who ate goats cheese in France whilst 37 weeks pg. She got food poisoning, and a previously healthy foetus died. OK, this might be an 'urban myth', as it is supposed to be a woman that my SIL knows, but why take the risk? I agree that the risks inherent in soft cheese are probably negated by cooking, but other food no-no's are just common sense.
I did not drink a drop of alcohol whilst pg with ds, and I know now that this was a bit excessive. However, I was very worried about any chance of mis-carrying. With my second, I would have a drink a week I think, if I fancied it. The only reason that I would not have steak during pregnancy is that I like my steak on the bloody side, and I can't stand well-done shoe leather!
