Salt (NaCl) is not excactly sodium (Na).
It is not right to use these terms as synonyms.
The FDA recommended limit of sodium is 2,300 mg per day (or even less - about 1500 mg while one is on low sodium diets).
This is much less than the weight of salt.
(5,750 mg per day or 3,750 mg for low sodium diet) and not so convenient to calculate.
Know how much sodium is in your salt - without a calculator:
1/4 tsp salt = 600 mg sodium
1/2 tsp salt = 1200 mg sodium
3/4 tsp salt = 1800 mg sodium
1 tsp salt = 2300 mg sodium

Phosphoric acid is used as an additive to acidify foods and beverages such as various colas and jams.
It provides them a tangy or sour taste and then, to mask and balance the acidity they add a huge amounts of sweeteners.
Remember! It’s a corrosive acid and can form toxic fumes when it comes into contact with alcohols, ketones and other organic compounds.
Phosphoric acid has been linked to lower bone density, dental erosion, risk of developing kidney disease.
BTW: The clear sodas that contained citric acid didn’t have the same risk.
