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

This volume includes both naturally occurring from ingredients and specially added sugars.
USDA tells us that last years each American consumed an average 130 pounds of caloric sweeteners per year!
That works out to 30 tsp of sugars per day approximately 480 extra calories!
Just to think: Eating just 200 more calories daily than your body requires for body functioning and exercise leads to a 20-pound weight gain in a year.

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.
