- Think back over everything you ate today (or plan to eat today). Enter the number of servings of each item you consumed or will consume.
- Enter 0 for items you did not eat — all fields start at 0, so you only need to update the ones that apply.
- The total sodium estimate updates live as you type. The progress bar turns amber when you approach the 2,000 mg target and red when you exceed it.
- Use the result to identify your single biggest source — that is the item to address first. Often one change (replacing patis with calamansi, or skipping the sinigang-mix packet) cuts intake by 1,000–1,500 mg.
- Repeat daily for one week to understand your typical patterns before making changes.

When to Use
Use this tool any time you want to understand how much sodium you are consuming from typical Filipino meals. It is especially useful for patients with CKD, hypertension, heart failure, or edema who have been advised to limit sodium but are unsure which foods are the largest contributors.
Appropriate population
Adults with CKD (any stage), hypertension, edema, or heart failure who have been counseled on a sodium-restricted diet. Also useful for family members who prepare meals for a patient. Most relevant for Filipinos eating a traditional diet — the food items are calibrated to Philippine commercial product values and standard carinderia portions.
Limitations to keep in mind
This is an estimator, not a precise laboratory measurement. Sodium content varies by brand, recipe, and portion size. A carinderia sinigang may have more or less than the reference value depending on how many sinigang-mix packets were used. Use this as a planning tool to identify your highest-sodium habits — not as an exact daily measurement. For precise dietary analysis, a registered nutritionist-dietitian consultation is recommended.
Pearls & Pitfalls
Target the highest-impact source first
One tablespoon of patis contributes more sodium than two pandesals. One bowl of sinigang contributes more than three snack packs. The principle of highest-impact-first means eliminating or substituting the single largest source in your typical day will produce more measurable change in BP and weight than eliminating ten small sources. Use this calculator to rank your sources, then replace the top one.
Practical swaps that preserve flavor
Remove patis → use calamansi + garlic + black pepper as a dipping sauce (~30 mg sodium). Remove sinigang mix → make tamarind broth from sampalok (~80 mg per bowl vs 1,500 mg). Swap corned beef → fresh bangus or tilapia (~80 mg per serving). Remove the seasoning packet from instant noodles entirely and stir-fry the noodles with garlic and vegetables. These four changes alone can reduce a typical Filipino day from 4,500 mg to under 2,000 mg.
Pitfalls
(1) "Low-salt" or "light" soy sauce still contains 600–800 mg per tablespoon — it is lower, not low. (2) Salt substitutes (potassium chloride products such as "Nurture" or "NuSalt") can cause dangerous hyperkalemia in CKD — do not use without nephrology approval. (3) Sodium restriction while on diuretics requires monitoring for hyponatremia, especially in elderly patients or those with low oral intake — tighten restriction gradually and recheck electrolytes after 2–4 weeks.
Why Use It
Most Filipinos consume 3,000–5,000 mg of sodium per day — two to three times the 2,000 mg CKD target and well above the WHO recommended maximum of 2,000 mg for any adult. The principal sources are not the salt shaker: they are the hidden sodium in condiments (patis at 1,420 mg per tablespoon, toyo at 900 mg per tablespoon), seasoning packets (Knorr cubes at ~1,400 mg each, Magic Sarap sachets, sinigang mixes at ~1,500 mg per packet), and processed meats (Spam, corned beef, tocino, longganisa). A single fast-food meal delivers roughly 1,000 mg. A patient who eats two tablespoons of patis and a bowl of sinigang with a sinigang-mix packet for lunch has already consumed more than 4,000 mg — twice the daily target — before dinner. Sodium reduction of just 1–2 g/day lowers systolic blood pressure by 3–8 mmHg and reduces proteinuria by 20–30% independently of antihypertensive medications. For dialysis patients, each gram of sodium consumed retains approximately 200 mL of fluid, directly increasing the interdialytic weight gain.
Add up a typical day. The number is usually a surprise.
Enter the number of servings of each food you typically eat in a day (use 0 if you do not eat it). The total updates live and is compared against the standard 2,000 mg CKD target.
Estimates are based on average commercial product values and standard carinderia portions. Individual portions and recipes vary; the calculator is a planning aid, not a precise measurement.
Next Steps
Use the result to support — not replace — clinical judgment.
- Interpret the value against the targets shown in the calculator and the Evidence section below, in the context of the full clinical picture.
- Trend serial measurements rather than acting on a single result; confirm abnormal or unexpected values before changing management.
- Apply the relevant KDIGO / specialty-guideline threshold and document the indication.
- Escalate or refer to nephrology when results are out of range, rapidly changing, or discordant with the clinical picture — and discuss the implications with the patient.

Formula & Equations
The calculator multiplies the number of servings entered for each item by its estimated sodium content in mg, then sums all items:
Total sodium (mg) = ∑ [servings × sodium per serving] for all items
| Food Item | Reference Sodium | Source |
|---|---|---|
| Pandesal / sliced bread | 120 mg per piece | FNRI Philippine Food Composition Tables |
| Pancit canton (carinderia or instant) | 1,720 mg per serving | Instant noodle label; carinderia average |
| Sinigang (with sinigang mix) | 1,500 mg per bowl | Knorr/Mama Sita sinigang mix packet |
| Adobo (standard cup) | 1,200 mg per cup | FNRI recipe estimate; toyo + salt |
| Patis (fish sauce) | 1,420 mg per tablespoon | Rufina Patis label |
| Toyo (soy sauce) | 900 mg per tablespoon | Silver Swan / Kikkoman label |
| Corned beef / Spam / luncheon meat | 800 mg per serving (~85g) | CDO / Purefoods product labels |
| Longganisa / tocino / hotdog / daing na bangus | 700 mg per piece/serving | Local product label averages |
| Bouillon cube / Magic Sarap sachet | 1,400 mg per cube/sachet | Knorr / Ajinomoto label |
| Fast-food meal (main + side) | 1,000 mg per meal | Jollibee / McDonald's Philippines nutritional disclosures |
| Snack pack (chips / crackers) | 400 mg per pack | Oishi / Jack & Jill label averages |
Evidence & References
The 2,000 mg sodium target for CKD patients is supported by two international guidelines. KDIGO 2024 recommends sodium intake below 2 g/day (equivalent to 5 g of table salt) for all adults with CKD based on randomized trial evidence showing benefits for blood pressure, proteinuria, and kidney function trajectory. The World Health Organization 2012 Sodium Guideline set the same <2 g/day target for all adults based on meta-analysis of randomized trials, with renal and cardiovascular outcomes as the primary endpoints. The PURE study data from 18 countries — including the Philippines — confirmed that most populations in Southeast Asia consume 3,000–5,000 mg/day, making this the largest evidence-practice gap in preventive nephrology.
