Brussels sprouts are one of the lowest-sodium vegetables you can add to your plate — raw sprouts contain only about 25 mg of sodium per 100 g. However, the way you cook them changes the story: boiling in salted water, roasting with a salty seasoning blend, or adding even a pinch of table salt can quickly turn a heart-healthy side dish into a high-sodium one.
This Brussels sodium calculator estimates the sodium content of your serving based on weight, preparation method, and any salt added to the batch. It also shows the daily value percentage using the FDA reference of 2,300 mg per day, making it easy to compare your serving against your daily sodium budget. Whether you are tracking sodium for hypertension, following a low-sodium kidney-friendly diet, or just curious about your veggies, this tool gives you a fast, realistic estimate in seconds.
🥦 Brussels Sprout Sodium Calculator
Estimate sodium per serving based on amount, preparation, and added salt.
Why the Cooking Method Changes the Sodium Count
Brussels sprouts are naturally a very low-sodium vegetable. Raw sprouts contain roughly 25 mg of sodium per 100 g, which is barely 1 percent of the FDA's 2,300 mg daily reference value. That makes them a smart choice for anyone watching blood pressure or following a low-sodium dietary pattern.
The number changes with handling. Boiling in unsalted water lowers the sodium density to about 19 mg per 100 g because some minerals leach into the cooking water. Steaming keeps it near 20 mg, and roasting without salt leaves about 23 mg per 100 g. But the real sodium leap comes from added salt: a 1/4 teaspoon of table salt contains about 580 mg of sodium, and if that salt is spread over a four-serving batch, each serving gets about 145 mg. This calculator separates the vegetable's natural sodium from the salt you add, so you can see exactly where your total comes from.
How This Calculator Works
The calculator starts by converting your serving size into grams. It uses the following approximations: 1 cup of raw Brussels sprouts weighs about 88 g, one medium sprout weighs about 19 g, and 1 ounce equals 28.35 g. Next, it applies the sodium density for your chosen preparation method and finally adds the sodium from added salt divided by the number of servings in the batch.
Percent daily value is calculated against the 2,300 mg reference used on American nutrition labels. Because actual sprout sizes and salt crystal sizes vary, treat the result as a practical estimate rather than a laboratory measurement.
Worked Example
You roast 300 g of Brussels sprouts (about 3.4 cups) with a little olive oil and no salt, then divide them between 3 plates. Enter 300 in the serving field, choose grams, select Roasted no salt, set servings to 3, and choose None for salt. The calculator multiplies 300/100 × 23 = 69 mg for the whole batch, then divides by 3 to give 23 mg per serving. That is just 1 percent of the daily value.
Now add 1/4 tsp salt to the same batch. The 580 mg of salt sodium is divided across 3 servings, adding about 193 mg. Each serving now has about 216 mg, or 9.4 percent of the daily value. The same vegetable can go from very low sodium to moderate sodium simply by salting the batch.
Standard Sodium Reference Values
These are approximate sodium densities per 100 g of edible portion, based on USDA FoodData Central values and standard cooking assumptions.
| Preparation | Sodium per 100 g |
|---|---|
| Raw | 25 mg |
| Boiled, drained, no salt | 19 mg |
| Steamed, no salt | 20 mg |
| Roasted, no salt | 23 mg |
| Frozen, cooked, no salt | 18 mg |

Low-Sodium Cooking Tips
- Season with garlic powder, onion powder, lemon zest, black pepper, or smoked paprika instead of salt.
- If you boil sprouts, use unsalted water and drain them well; this keeps sodium closer to the 19 mg per 100 g baseline.
- When a recipe calls for salt, add it to the whole dish, not to each plate. That way you can calculate per-serving sodium accurately.
- Rinse canned or pre-seasoned frozen sprouts if the label shows added sodium.
Frequently Asked Questions
Are Brussels sprouts high in sodium? No. In their plain form they are a very low-sodium vegetable. Even a 200 g serving of raw sprouts contains about 50 mg of sodium, or just over 2 percent of the daily value.
Can I eat Brussels sprouts on a low-sodium diet? Yes, as long as you control added salt. Boiled or steamed sprouts with no added salt are excellent for low-sodium meal plans. If you are also limiting potassium for kidney reasons, check with your dietitian, since Brussels sprouts are a potassium-containing vegetable.
Why does the daily value percentage matter? The FDA uses 2,300 mg as the reference amount for sodium on Nutrition Facts labels. Knowing the percentage helps you see how one serving fits into your daily budget at a glance.
How accurate is this calculator? It uses standard food-composition values and common portion conversions. Exact sodium can vary with growing conditions, variety, cooking time, and salt measurements. Treat the result as a close estimate, not a lab result. For a higher-sodium comparison, try the sausage sodium calculator.
