I didn't want to derail the thread on pasta with a tangent discussion on sodium, but I wanted to address your post and open discussion of sodium in general. I'm not surprised to hear that you had more head rushes without it. Lack of sodium in the diet leads to a lower blood volume and it's harder for nutrients and oxygen to get around the body to where they are needed. There's actually no good evidence that sodium intake negatively affects your health, be it by messing up your BP or increasing your risk of cardiac issues. That's one of the biggest, most unfortunate myths in the nutrition world, and many a people walk around tired, flat, and weak because they are chronically deprived of socium, which causes the body to also flush out tons of potassium and so you end up being deficient in both. You can't have a lot of one without the other, as the body uses them to maintain an ionic balance between the inside and outside of every cell in your body. If you don't get enough sodium, you won't have much potassium and it works the other way to. Ironically, everyone knows you should eat lots of potassium and keep your sodium low! This has no basis in the way the body actually works however. I suggest you say goodbye to head rushes and hello to pickles and soy sauce!
