“You really shouldnt avoid salt. Your body depends on it.”
I’ve heard that too. There doesn’t appear to be any science behind the idea of limiting sodium - and what little science there is happens to be in the opposite direction, as in NOT having a lot of salt increases risks of bad things.
There are maybe 12% of people who are hypertensive with severe sodium issues, so those people may benefit from less sodium, but for the rest of us, bring it up!
I lose so much so salt working out, that more than makes up for the salt I eat.
I like to drink pickle juice after a workout, it’s amazing how much better I feel right after I drink it.
