why do we need new electrons in our body? Why do we need a flow of any element who’s sole purpose is to provide an electron? Why can we not just have x amounts of sodium, potassium and other? Is it purely a side effect of fluid balance?

Because the body is not a closed system. You lose salts when you sweat; certain molecules break in ways that metabolism can’t fix and therefore have to be removed. Of the molecules that break, some can be reforged using internal resources, and some can’t. We call the ones that can’t be reforged essential vitamins, proteins, and fats. Certain chemicals that can be reforged aren’t reforged at optimal levels – creatine is one example. These are called pseudovitamins, because the body benefits healthwise from supraphysiological levels.

Bottom line though, the body has to purify itself to remain optimally functional. This means that it needs intake to replace lost resources. Absent such intake, the body will eventually fail because it will run out of internal stockpiles of such materials, and either be completely *out* of them – this happens with simple things like sodium – or lack the chemical processes to remake other parts of itself into those nutrients – vitamins, the “essentials”.

Even if the body could make vitamins and the “essentials” it would have to make them out of other parts of itself. Those molecules would eventually become irreparably damaged and excreted. Eventually, the body would reach the point that further self-canabalism would damage the organs. It also does this in its current state – this is why people die of death by malnutrition.
