Wonderful quote targeting system you have installed.
What, we were talking about ramen noodles, right?
Basically, salt, Sodium Chloride is a poison, I don't know why people are so unconcerned about it's deleterious effect on their health. It's almost the sole physiological cause of essential hypertension.
It's also an ion that is vital in keeping things like your kidneys and nerves functioning. Don't get me wrong, that is a big part of why too much is gonna fuck you up, if I recall correctly, but calling it a poison is about as accurate as calling water a poison. You can overdose on both (and I'm not even referring to drowning), but you need a minimum amount in your diet. The main difference is that it's really hard to get too much water accidentally, and it's really easy to get enough salt without trying.
But I digress. The point I'm trying to make here, is that in many cases, it's a lot more complicated than "poison" vs "not poison".
Right, "the dosage makes the poison" but you really need very little sodium chloride to stay healthy, far below the 2,500mg the daily recommended level in the US suggests. Less then 1,500mg a day would be better and the bare minimum to sustain life functions is like 25mg/day. Anything more then a minimum amount, is deleterious to your health because of how taxing it is on your body to eliminate.
What gets me is how pervasive sodium is in foods. It's in everything and a typical western person is almost certain to go over 2,500mg/day without even trying. It's simply way too much and people eating things like ramen noodles with 1600mg of sodium in a package, it's far beyond what you need and it essentially becomes a poisonous dosage if levels like that are consumed regularity.
I think MSG is safer to consume then excess sodium, unless you are sensitive to it which a lot of people are.
