yeah I can't figure it out. according to google, raw pork has 53mg of sodium per 3-oz serving, and broccoli has 49. I can't figure out how to get exactly the salt content but it's the sodium that's bad for you, right?
edit - okay maybe they're talking about bean based alternatives like soy? that's got like 4mg, pinto beans have 1
Yeah, salt normally refers to sodium content. Salts separate in solution, so you never have actual NaCl unless you have a solid hunk of salt.
But also, sodium isn't inherently bad for you. Just like most things we consume, too little is bad, and too much is also bad. 53mg per serving is still so far off from what a typical adult needs.
I don't know if you mean that 3oz sounds high or low. It certainly sounds like a normal serving size to me. I normally aim for about 7oz per meal if I'm having pork, but I'm pretty sure that's on the high end. Even then, it's just a little over 100mg of sodium. I've seen the recommended minimum daily sodium for healthy adults to range anywhere between 500mg and 2000mg depending on the source.
And yes, I do mean it breaks up into sodium and chlorine. It makes sense to talk about "salt concentration" in the context of salt dissolved in distilled water, but less so when you have so many other things in solution because there's no straightforward way (to the best of my knowledge, but I'm also no chemist) to map from dissolved ions to the molecules they would've been a part of.
