On junk food it's good if it's "low sodium" but now we drink these 1000mg sodium electrolyte packets?

I don't get it. Someone please explain

Sodium isn't necessarily bad. For eg, if you sufficient water right before eating high-sodium food, you're 100% fine. You just can't reverse that order or ignore the water altogether. 

The point: It's the sodium-water balance that matters.

So if you consume sodium as part of a fluid, you're not upsetting the balance.
