3rd baby here. Had my first over 14 years ago and the banned foods list was so different then. Heaven forbid we came within sniffing distance of a soft egg or a smidge of peanut butter!
This time I've eaten pretty much everything. Sushi is perfectly safe as it will have been frozen, and if you're a heathen like me an get supermarket stuff then there's nothing raw in there anyway.
Rare beef is also considered fine now as long as it's a whole cut rather than mince, as the outside will have been seared and the inside can't have been contaminated. So rare steak is fine, rare burgers are not. I was in America in June and gleefully ate a piece of beef bigger than my head that a good vet could have revived. God it was delicious!
Peanuts are now considered a good idea nutrition wise, plus it seems to actually reduce the rates of deadly allergies if babies are exposed in utero. I absolutely haven't ever stood in the kitchen at 4am with a jar and a spoon... honest!
The only things I wouldn't ever touch are pate and other high vitamin a things (seriously harmful for the baby in too high a dose), cigarettes (obviously) and alcohol. My DP has a DC from a previous relationship who has very sadly been affected by the mother's alcohol consumption. The problems this child faces are horrendous, utterly heartbreaking. I've read an awful lot about alcohol and pregnancy and it just can't be guaranteed to be safe at any level. It's a bit of a lottery - alcohol in the baby's blood at just the wrong moment of brain development can have an impact. The same amount of alcohol just a few hours earlier or later could have no effect at all. I don't want to scare monger, and obviously no judgement on those that do enjoy the odd glass, but for our family it's a risk we just wouldn't take. NHS guidelines have also recently changed to reflect the 'no safe amount' stance.
I should point out that I had the odd half a guiness with my first pregnancy, plus mulled wine at Christmas and he is thoroughly perfect and a strapping teenager now, so no one should panic!
