Many sodium tracking routines focus on obviously salty snacks and processed meats, but white foods — from bread and pasta to milk, tofu, and white beans — quietly contribute to your daily total. The White Sodium Calculator estimates the sodium content of a wide range of white-colored foods based on your portion size, so you can see exactly how much a bowl of rice, a slice of bread, or a serving of creamy white sauce adds to your intake.
Select a food, enter your portion in grams, ounces, or servings, and adjust your personal daily sodium target if needed. The calculator then returns the sodium in milligrams, the percentage of your daily value, and a simple per-100g classification to help you decide whether a food is low, moderate, or high in sodium.
This tool is designed for home cooks, meal planners, and anyone following a heart-healthy or low-sodium diet. Keep in mind that packaged and restaurant versions can vary, so use the estimates as a guide and check nutrition labels whenever possible.
Estimate sodium from common white-colored foods and see how it fits your daily limit.

How the Sodium Estimate Is Calculated
This calculator estimates sodium from a food's average mg-per-100g value. Once you choose a food and enter a portion, the tool converts your portion to grams (1 ounce = 28.35 grams) and multiplies by the food's sodium density. For example, if a food contains 380 mg of sodium per 100 g and you eat a 60 g serving, the math is 380 × (60 ÷ 100) = 228 mg.
Because serving sizes vary, we give each food a 'typical serving' weight — one slice of bread is about 30 g, a cup of cooked rice is about 150 g, and a glass of milk is about 240 g. If you select the 'serving' unit, the calculator uses that weight automatically. You can also enter grams or ounces to match your kitchen scale or a food label.
Step-by-Step Examples
Let's look at a 50 g serving of mozzarella. With an average of 370 mg sodium per 100 g, the estimate is 370 × (50 ÷ 100) = 185 mg. That's about 8% of a 2,300 mg daily limit, which shows why cheese can be a significant source even in modest portions.
Now try two slices of white bread, about 60 g total. At 490 mg per 100 g, the result is 490 × (60 ÷ 100) = 294 mg, or 12.8% of the daily value. Bread's sodium adds up quickly because it is often eaten in multiple servings throughout the day.
Sodium Reference Table for Common White Foods
Values below are approximate averages from USDA FoodData Central and represent cooked or prepared forms without added salt unless noted. Use them to compare foods and plan portions.
| Food | Sodium per 100 g | Typical serving | Sodium per serving |
|---|---|---|---|
| White rice, cooked | 1 mg | 1 cup (150 g) | 2 mg |
| White pasta, cooked | 1 mg | 1 cup (150 g) | 2 mg |
| Boiled white potato | 4 mg | 1 medium (150 g) | 6 mg |
| Cauliflower | 30 mg | 1 cup (100 g) | 30 mg |
| Whole milk | 40 mg | 1 cup (240 g) | 96 mg |
| Egg white, cooked | 166 mg | 1 large (60 g) | 100 mg |
| Canned white beans | 320 mg | ½ cup (130 g) | 416 mg |
| Mozzarella | 370 mg | 1.5 oz (50 g) | 185 mg |
| Béchamel sauce | 380 mg | ¼ cup (60 g) | 228 mg |
| White bread | 490 mg | 1 slice (30 g) | 147 mg |
| White chocolate | 80 mg | 1 oz (40 g) | 32 mg |
These are general estimates. Packaged breads, canned beans, and restaurant sauces can contain much higher sodium because of added salt and preservatives.
Tips for Managing Sodium in White Foods
Not all white foods are high in sodium. Starches like plain rice, pasta, potatoes, and cauliflower are naturally very low in sodium. The sodium usually appears when salt is added to cooking water, sauces, or dough. To keep them low-sodium, cook pasta and rice without salt, avoid salting the pot, and season with herbs, lemon, garlic, and spices instead.
Dairy foods like milk and mozzarella contain naturally occurring sodium, but they also provide calcium and protein. If you are tracking sodium for blood pressure or heart failure, account for cheese and sauces separately because they are often the largest sodium contributors in white-colored meals.
Frequently Asked Questions
Is white bread high in sodium? Yes, most commercial white bread contains about 100–190 mg per slice, so two slices can contribute 200–380 mg. Bread is often overlooked because it doesn't taste salty, but eating several servings a day can exceed 1,000 mg just from bread.
Does boiled white rice have sodium? Plain boiled white rice contains almost no sodium (about 1 mg per 100 g) when cooked without salt. The sodium increases when rice is cooked in salted water, seasoned with soy sauce, or bought as instant or seasoned rice mixes.
How is the Daily Value calculated? The tool divides sodium in milligrams by your chosen daily target and multiplies by 100. We default to 2,300 mg, the FDA's Daily Value, but if your doctor recommends 1,500 mg or another limit, adjust the field to see your personal percentage.
When to Use This Calculator
Use the White Sodium Calculator when planning meals, comparing breakfast options, tracking micronutrients, or preparing a low-sodium eating pattern. It is especially handy for people on DASH or heart-healthy diets who want a quick estimate without looking up nutrition tables. If you also track sodium from other produce, the vegetable sodium calculator and cranberry sodium calculator can help round out your day.
