Just based on my individual experience, sodium is by far the worst chemical which affects my body negatively. Sugar I can burn up by lots of activity, but excess sodium is hard to get rid of, especially in cool climate such as here in Seattle area. NaCl most certainly raises my BP which then has cascading bad effects on other issues.
And I’m just the opposite. Sodium seems to get flushed out of my system rapidly, but sugar sticks around and causes weight gain in very little time.
