Daily sodium is summed from table salt — which is 39% sodium by mass, so 6 grams of salt contains about 2,360 mg sodium — plus packaged food contributions that typically dominate intake. The USDA daily upper limit for most adults is around 2,300 mg, while people managing hypertension are sometimes advised toward 1,500 mg, and the calculator explicitly shows both comparison bars so you see where a single salty restaurant meal lands relative to the whole day's budget. It counts sodium, not salt weight, to match nutrition labels that quote milligrams directly.
Processed staples like bread, cheese and deli meats often contribute more cumulative sodium than the shaker, because they are eaten frequently. If the calculator flags high totals, scanning those staple labels for lower-sodium alternatives usually moves the bar more than simply using less table salt, and hydration with potassium-rich foods supports balance in consultation with a clinician.
Sodium's health link runs through blood pressure: excess sodium expands extracellular fluid volume and, in salt-sensitive individuals (~30–50% of hypertensives), raises arterial pressure dose-dependently. Population trials (DASH-Sodium) show cutting from 3,300 to 2,300 to 1,500 mg stepwise lowers systolic pressure, especially when paired with potassium-rich DASH diets.
Not everyone needs 1,500 mg — highly active people in heat can lose 500–1,000 mg hourly in sweat, and restrictive low-sodium diets carry their own risks (hyponatremia, iodine shortfall if salt is the iodine vehicle). Athletes, outdoor workers and those on diuretics should personalize, not blindly minimize.
Label math traps: "low sodium" means ≤140 mg per serving, "very low" ≤35 mg, but serving sizes are often tiny (a soup can may hold 2.5 servings). Multiply per-serving sodium by servings you actually eat, and watch "reduced sodium" which is only 25% less than the original — still high if the original was extreme.
Practical reduction levers ranked by impact: cook more from scratch (cutting 300–600 mg daily), choose "no salt added" canned goods and breads, flavor with herbs, acids and umami instead of salt, request sauces on the side, and rinse canned beans. Small daily cuts compound: 400 mg less daily equals 12 grams monthly — enough to shift pressure meaningfully over quarters.
Check sodium intake from foods and salt — see daily total, % of limit, and low-sodium swaps. Formula: Total = meals + salt*2300mg (1 tsp salt ≈ 2300mg sodium).

With 1,800 mg from meals plus 0.5 tsp salt (1,150 mg) = 2,950 mg total, 128% of the 2,300 mg limit and 197% of the 1,500 mg hypertension target — over by 650 mg. Swapping one deli sandwich for home-cooked drops ~600 mg, bringing it back to limit in a single choice.
