Well said. You need as much as you use, kinda like carbs/cals. It's not a complicated concept, but figuring out how much you NEED is not easy. Staying consistent with diet helps.This is one of those things where your lifestyle dictates these things more than anything else.
I think sodium is a tremendous performance enhancer given proper hydration, and if the workload necessitates increased intake.
A middle aged overweight guy who barely moves would be ill advised to eat a ton of sodium; not nearly as much due to sodium's ill effects, but due to the poor body composition, eating habits, and hydration of such individual.
The workload creates the demand
Sodium may not even be an issue. And the egg came before the chicken....
My blood pressure goes through the roof when I add in to much sodium. I've tried to follow Stan efferdings recommendations a few times now and it always made my bp increase and make me feel winded all the time. Performance was increased dramatically but I always felt out of breath. I used Pink salt
Sodium elevates bp, salt doesnt. Look into the benefits of Himalayan pink salt. It doesnt elevate bp and has many health benefits and minerals
A salt like potassium chloride tastes ok. There is salt at the grocery store that is sodium chloride and potassium chloride mixed together in a ratio. That is helpful if your BP is borderline and you still want the taste.
