Bell peppers are one of the most versatile vegetables in the kitchen — and one of the lowest in sodium. A whole medium red bell pepper contains only about 4–5 mg of sodium, well under 1% of the 2,300 mg daily reference value. This calculator converts any serving — grams, ounces, cups, or whole peppers — into an estimated sodium total and shows its share of the daily value.
Whether you are following a low-sodium diet for hypertension, managing kidney disease under medical supervision, or simply tracking daily micronutrients, the Bell Sodium Calculator gives you fast, reliable numbers. Use the one-tap preset buttons or enter a custom amount in your preferred unit, then copy the result straight into your food diary. It fills a small but useful gap for anyone who already counts sodium in eggs, popcorn, and other everyday foods.
🥫 Bell Pepper Sodium Calculator
Estimate the sodium in fresh red, green, yellow, or orange bell peppers.
Step-by-Step Guide
Start by choosing the pepper variety that matches what you are eating — red, green, yellow, or orange. Although they are the same species, their sodium values differ slightly, so a precise selection gives a more accurate estimate. Next, enter a serving size in grams, ounces, cups of chopped pepper, or whole medium or large peppers. The preset buttons fill in common portions like 100 g, 1 cup, 1 medium, or 1 large with a single tap, and you can type any custom amount if your serving does not fit a preset.
Press Calculate sodium, and the tool converts your serving into grams, applies the vegetable's sodium-per-100 g value, and reports the total in milligrams plus its share of the 2,300 mg daily reference value. The breakdown panel repeats the key numbers so you can see exactly how the estimate was built.

Calculation Method
The calculator uses a two-step method. First, the serving size is converted to grams using standard weights for raw bell pepper portions: 1 ounce = 28.3495 g, 1 cup of chopped pepper ≈ 149 g, 1 medium pepper ≈ 119 g, and 1 large pepper ≈ 164 g. These portion weights come from USDA FoodData Central and represent averages — a particular pepper may differ by 10–15%. Then the sodium is calculated with the formula:
Sodium (mg) = grams × (sodium per 100 g) ÷ 100
For example, a medium red pepper weighs about 119 g and red bell peppers contain about 4 mg sodium per 100 g, so the total is 119 × 4 ÷ 100 = 4.76 mg. The daily value percentage is simply that total divided by 2,300 mg and multiplied by 100. The tool reports two decimal places for transparency, but with numbers this small, rounding to one decimal or even to the nearest whole milligram will not change practical food-logging decisions.
1 medium red pepper: 119 g × 4 ÷ 100 = 4.76 mg sodium, about 0.21% DV.
1 cup chopped green pepper: 149 g × 3 ÷ 100 = 4.47 mg, about 0.19% DV.
3 oz yellow pepper: 85.05 g × 2 ÷ 100 = 1.70 mg, about 0.07% DV.
A 500 g red pepper bowl (raw or lightly cooked): 500 × 4 ÷ 100 = 20 mg, about 0.87% DV.
Why the Numbers Are So Small
Bell peppers are naturally very low in sodium because the plant does not accumulate sodium in its flesh the way processed foods do. The sodium figures you see here — roughly 2–7 mg per serving — are trace amounts. By comparison, a single slice of deli turkey can contain 250–400 mg, and a cup of canned soup often contains 600–800 mg. This is why bell peppers are a staple in low-sodium and DASH-style eating plans: they add volume, vitamin C, and color without measurably moving your daily sodium budget.
Reference Table
| Serving | Approx. weight | Sodium (red) | Sodium (green) |
|---|---|---|---|
| 1 cup chopped | 149 g | 6.0 mg | 4.5 mg |
| 1 medium pepper | 119 g | 4.8 mg | 3.6 mg |
| 1 large pepper | 164 g | 6.6 mg | 4.9 mg |
| 3 oz (85 g) | 85 g | 3.4 mg | 2.6 mg |
| 100 g | 100 g | 4.0 mg | 3.0 mg |
Frequently Asked Questions
Is canned bell pepper higher in sodium? Yes, often dramatically. Canned or jarred peppers are usually packed in brine, which can push sodium to 300–400 mg per half-cup, depending on the brand. Rinsing them under water removes some of the surface salt but not all of it. If you are on a strict low-sodium diet, fresh or frozen plain peppers are the safer choice.
Do green peppers really contain less sodium than red peppers? Slightly. Fresh raw green peppers average about 3 mg per 100 g, while red peppers average about 4 mg per 100 g. Yellow and orange peppers sit near 2 mg per 100 g. These differences are small in absolute terms, but the calculator keeps them separate so your estimate is as close as possible.
Why is the daily value based on 2,300 mg? The FDA uses 2,300 mg as the Daily Value for sodium on Nutrition Facts labels, based on federal dietary guidance. If your doctor has recommended a stricter target, such as 1,500 mg, divide the total sodium by that number instead — a 4.76 mg pepper would be 0.32% of a 1,500 mg goal.
Limitations
Sodium content in fresh peppers varies with growing conditions, variety, ripeness, and exact fruit size. Cooking with salted water or adding seasoning introduces sodium that this tool cannot predict. The portion weights are averages, and a large pepper in your kitchen may weigh more or less than 164 g. For clinical or medical nutrition advice, confirm current figures with the USDA FoodData Central database and consult a registered dietitian before making diet changes.
