CalcVitalsSodium Tracker — Daily Total vs the Limits
Most sodium hides in processed food, not the salt shaker. Two slices of deli ham, a cup of canned soup and a slice of pizza already total about 2,085 mg — over 90% of the 2,300 mg daily guideline before anything else is eaten. Pick your own items below and watch how fast it climbs.
How it works
Sodium is the quiet nutrient: roughly three-quarters of it arrives inside processed and restaurant food, decided by manufacturers, not by your hand at the table. Bread is the classic ambush — individually modest per slice, but eaten at every meal it out-salts many obviously salty snacks. This tracker exists to make the invisible arithmetic visible for a day of eating.
The two comparison lines come from mainstream guidance: 2,300 mg a day is the upper limit in US dietary guidelines, and 1,500 mg is the American Heart Association's ideal, with the strongest blood-pressure evidence in people who are salt-sensitive, older, or already hypertensive. Moving from typical intakes (around 3,400 mg in the US) toward the guideline produces modest average blood-pressure falls — small per person, large across a population.
Use the tracker as an audit, not a sentence. One day over the line is noise; the pattern across a week of typical eating is the signal. If the total startles you, the highest-yield swaps are usually soups, processed meats, instant noodles and restaurant meals — the items that contribute four-figure milligram counts in a single serving.
The method
Food sodium values are typical figures from USDA FoodData Central entries for each item, per the serving described. Salt equivalent = sodium × 2.5 (sodium is ~39.3% of sodium chloride by mass). Guideline lines: 2,300 mg (US Dietary Guidelines) and 1,500 mg (AHA ideal).
Frequently asked questions
Is sodium the same as salt on labels?
No — labels in the US list sodium; in some countries labels list salt. Salt = sodium × 2.5. A product with 800 mg sodium per serving contains about 2 g of salt per serving.
Does drinking more water cancel out sodium?
Not in the way people hope. Water balance and sodium are regulated together by the kidneys; chronic high intake is a blood-pressure issue, not fixed by dilution. Adequate potassium (fruit, vegetables, legumes) genuinely does blunt sodium's effect.
Should everyone aim for 1,500 mg?
The clearest benefit is for people with high blood pressure or salt sensitivity. For everyone, staying under 2,300 mg is the mainstream advice; going far below ~500 mg is neither necessary nor advised without medical direction.
