Enter Daily Sodium Inputs
Use label values when possible. For mixed meals, enter an average sodium amount per item or serving.
Tip: Packaged sauces, soups, breads, and restaurant meals often contribute more sodium than table salt alone.
Example Data Table
| Source | Servings | Sodium per serving | Total sodium |
|---|---|---|---|
| Breakfast sandwich | 1 | 820 mg | 820 mg |
| Canned soup | 1 | 690 mg | 690 mg |
| Restaurant dinner | 1 | 1200 mg | 1200 mg |
| Soy sauce | 2 | 290 mg | 580 mg |
| Added salt | 0.25 tsp | 575 mg | 575 mg |
Formula Used
Total sodium (mg) = meal sodium + restaurant sodium + processed food sodium + condiment sodium + sports drink sodium + added salt sodium + supplement sodium + custom food sodium.
Meal sodium (mg) = (breakfast items × breakfast sodium) + (lunch items × lunch sodium) + (dinner items × dinner sodium) + (snack items × snack sodium).
Added salt sodium (mg) = teaspoons of table salt × 2300.
Sodium density = total sodium ÷ calories × 1000.
Salt equivalent (g) = sodium in mg × 2.54 ÷ 1000.
Personal target defaults to 2300 mg, drops to 1500 mg for older adults or blood pressure concerns, then adjusts slightly for activity.

Frequently Asked Questions
1. Is sodium the same as salt?
No. Sodium is one component of salt. Table salt is sodium chloride, so salt weight is greater than sodium weight.
2. Why does the calculator show both 1500 mg and 2300 mg?
Many guidance models use 2300 mg as an upper limit, while 1500 mg is a stricter goal for many adults.
3. What counts as a high sodium density?
A higher mg per 1000 kcal suggests sodium-heavy foods. Compare similar calorie intakes to judge diet quality more clearly.
4. Are restaurant foods usually higher in sodium?
Often yes. Sauces, seasoning blends, processed ingredients, and large portions can raise sodium sharply even when foods taste balanced.
5. Should athletes always eat more sodium?
Not always. Sweat losses vary. Heavy training, long heat exposure, and specific medical advice matter more than labels alone.
6. Can low-sodium foods still seem salty?
Yes. Acids, herbs, umami ingredients, and texture can increase flavor perception without adding much sodium.
7. Is this calculator a medical diagnosis tool?
No. It is an educational estimator. Personal medical advice should come from a qualified clinician who knows your history.
