Hi bodybuildingcommune friends,
I have less idea about the title (How much salt is necessary for human consumption?) So please go through below
The sodium and chlorine in salt are electrolytes, minerals that conduct electricity in our fluids and tissues. The other main electrolytes are potassium, calcium and magnesium. Our kidneys maintain the balance of electrolytes and water by regulating the fluids that we take in and pass out of our bodies. If this balance is disturbed, our muscles, nerves and organs won't function correctly because the cells can't generate muscle contractions and nerve impulses.
