Hear, hear, angelico!
I'm all for not eating damaging foods. But me, I like science. And I know my way around scientific journals, too. The amount of proper, reliable research on the different foods for pregnancy (and let's not forget booze!) is negligible.
I will happily take any advice that is based in science and is not just superstition. Most of what we are being told is superstition, pure and simple. Prawns, by the way, are fine - just ask all the Thai mums with healthy babies :)
That mumsnet thread on what to eat is very sensible, and links to the food standards website (also vey sensible).
I also recommend everyone grabs a cuppa when they've got a spare minute and reads this: www.essentialbaby.com.au/life-style/nutrition-and-wellbeing/the-child-king-20120130-1qoqf.html
vcarroll - good on you, lady. You won't stop wanting them as long as you think you're missing out on something, though. You're really not missing out on anything, you just need to convince your brain that :)
I quit almost a year ago using the Alan Carr's easy way book. I can't recommend it highly enough. I have not had one single drag since I finished the book and stubbed out the last one... And I was a smoker for fifteen years STRAIGHT. Good luck!
