Whatever you do eat...DON'T eat licorice (the black kind). It can raise your blood pressure...in fact, they suggest you don't eat it while pregnant especially if you are prone to get PIH.
Me, while my BP looks fantastic now (usually around 118/68) it is extremely high for me and has been ever since my seizure medication made me fat. Back when I was healthy and running 5 miles most days my BP was 70/50 and that is while stressed, visiting the doctor. That is abnormal and generally considered inching close to death and scares nurses. I'm hoping though that getting in shape will get me closer to what was my normal abnormality.
The fact that I had PIH and got to about 180/110 when pregnant...extra scary.
As for good salt free things to eat. What do/don't you like? I'm trying not to use salt on pretty much anything right now unless I just can't stand it. I broiled some chicken that was fantastic IMHO.
I just sprayed the broiler pan with some pam, sprayed the chicken (you have to use something or it will totally dry out) and sprinkled yellow curry powder and some ginger on it...did the other side and called it good. Fantastic if you like mild curry...add more ginger and it isn't so mild.
I have always been more excited with the stronger curries like green or panang, but with broiled chicken I loved it. For salmon I used lemon and garlic on it...no salt, was nice. I've been using lots of lemon juice and ginger. They both have strong flavours and I think if you find flavours you like and keep them fairly strong...you don't miss the salt. I used to use tons of salt...seriously. I'd season food so that the family would like it and then add quite a bit more to my food. I haven't missed it really. For chicken we just go to Costco and get a bag of frozen breasts. I'd like to be able to get the organic, and I might just end up going ahead and doing it for my kids at least (arsenic content...you don't wanna know) but it is so much more expensive. Anyway, a chicken breast is about 6 ounces of chicken when you get it that way so it is fairly easy to figure out what your portion size should be. It doesn't really end up being that expensive. If you do like spicy curry..get a nice paste, a couple cans of low fat coconut milk (don't know the sodium content, sorry) and load it up with veggies and with that, 2 chicken breasts can easily go to feed 4-6 people. Put it on some brown rice and you are good to go. We always add some fish sauce (or did before I started dieting...I do still for the boys) but it is very salty...lime or lemon juice is a good addition and you can use low sodium soy sauce.
There are always ways to make food that won't be terribly expensive but can be very healthy.
