Couscous is a quick-cooking grain-like pasta made from durum wheat semolina. Plain couscous is naturally very low in sodium: dry couscous contains about 10 mg per 100 g, while cooked couscous contains about 5 mg per 100 g. The sodium in your bowl can rise quickly, however, if you cook it in salted water, use a seasoned boxed mix, or add salt at the table. This calculator separates the sodium naturally present in the couscous from any salt you add, so you can see exactly where the milligrams come from.
Use the tool to log sodium for blood pressure management, heart-healthy meal planning, or everyday nutrition tracking. Enter your portion size, choose the type and whether it is dry or cooked, and optionally add the salt used in cooking. Results give total sodium, sodium per 100 g, the equivalent amount of table salt, and how the portion fits within a 2,300 mg daily value.
It is especially handy for dietitians, students, and anyone following a DASH-style or low-sodium eating plan, where small amounts of hidden salt can add up across meals.
🧂 Couscous Sodium Calculator
Quick sodium estimate for plain, whole wheat, or seasoned couscous — including salt added while cooking.
How to Use This Tool
Select the type of couscous you are eating, then choose whether your portion is dry or cooked. Enter the amount in grams or cups. If you add salt during cooking or at the table, enter that amount as teaspoons or grams — the calculator converts it to sodium automatically. Press Calculate Sodium to see your results, and use Reset to clear the form and start a new session.
Quick presets: Use the preset buttons for common portions like 1 cup dry (180 g) or 1 cup cooked (157 g). These weights come from standard USDA serving sizes and are close for most brands.
How It Works
The sodium estimate is built from two sources. First, the couscous itself: plain dry couscous contains roughly 10 mg sodium per 100 g, and cooked plain couscous about 5 mg per 100 g. Whole wheat varieties are similar, while seasoned boxed mixes are much higher — often 200–300 mg per cooked serving before any added salt. Second, any salt you add: table salt is about 39% sodium by weight, so 1 g of salt contains about 390 mg sodium, and 1 teaspoon (about 6 g) contains about 2,300 mg.
The calculator adds the sodium from the couscous and the salt, then divides by the portion weight to give sodium per 100 g. It also shows the salt equivalent and how the total compares to the FDA Daily Value of 2,300 mg.
Worked Examples
Example 1: 1 cup cooked plain couscous (157 g) with no added salt. Sodium from couscous ≈ 5 × 157 / 100 = 7.9 mg. Total ≈ 8 mg, about 0% of the Daily Value.
Example 2: The same 157 g portion cooked with 1/4 teaspoon salt (about 1.5 g). Salt sodium ≈ 1.5 × 390 = 585 mg. Total ≈ 593 mg, or about 26% of the Daily Value. This shows how quickly table salt dominates the sodium count.
Example 3: A 1-cup serving of a seasoned boxed mix (prepared, about 140 g with seasoning). With a base value of 200 mg/100 g, sodium from mix ≈ 280 mg; if you add no salt, total stays near 280 mg — still over the 140 mg/100 g threshold for a low-sodium food.
Reference Data
| Couscous type | Dry sodium (mg/100 g) | Cooked sodium (mg/100 g) |
|---|---|---|
| Plain white couscous | 10 | 5 |
| Whole wheat couscous | 8 | 4 |
| Seasoned boxed mix (varies) | 400–800 | 150–300 |
Values are approximate. Seasoned mix values vary widely by brand and flavor; check the nutrition label for the exact number.
Tips & Best Practices
- Weigh the dry couscous before cooking for the most accurate dry-state sodium value, since water absorption affects the cooked weight.
- Rinsing cooked couscous with plain water can remove a small amount of surface salt, but it is not a reliable way to lower sodium.
- If you use a seasoned mix, skip the added salt entirely — most mixes already contain enough sodium.
- Use the sodium per 100 g result to compare couscous with other grains like rice or quinoa. A value under 140 mg/100 g qualifies as a low-sodium food in most labeling frameworks.
Frequently Asked Questions
Is plain couscous good for a low-sodium diet?
Yes. Plain couscous contains very little natural sodium, making it a smart base for low-sodium meals. The main risk is the seasoning or salt you add.
Why does cooked couscous have less sodium per 100 g than dry?
Because cooked couscous absorbs water, so the same amount of sodium is spread over a larger weight. This is a dilution effect, not a loss of sodium.
How accurate is this calculator?
It is an estimate. Natural sodium in couscous is fairly consistent, but seasoned mixes vary, and your salt measurements may not be exact. Use nutrition labels when available.
