Salt/ sodium.

Hi • Mommie of Twins. Baby A is a boy, Baby B is a girl.. I'm so excited and a new Mommie! 😊
I was told today by a mom that I'm not supposed to eat ANY salt because, it causes preclamsia. My doctor didn't say anything like this to me, now I'm all afraid and starving bc I don't know what to eat.. Is this true? I thought preclamsia is just something that's random. No way to avoid and it only comes to a certain percent of moms?
