Many people tracking their sodium intake for heart health, kidney conditions, or general wellness focus on processed foods and table salt — but did you know that some fruits naturally contain sodium too? While most fruits are low in sodium, certain varieties like celery, beets, and some tropical fruits can contribute meaningful amounts to your daily total. This Fruit Sodium Calculator helps you quickly estimate the sodium content of over 20 common fruits based on your serving size.
Whether you’re following a low-sodium diet for hypertension management, monitoring potassium-to-sodium ratios, or simply curious about the mineral profile of your favorite fruits, this tool provides instant, accurate results. Simply select a fruit, enter your serving weight in grams or ounces, and get the sodium content in milligrams along with a breakdown of how it fits into daily recommended limits. Perfect for dietitians, nutrition students, and health-conscious individuals.
🍎 Fruit Sodium Calculator
How to Use This Tool
Using the Fruit Sodium Calculator is straightforward. Start by selecting a fruit from the dropdown menu — the list includes 27 common fruits from apples to watermelon. Next, enter your serving size in grams or ounces. You can use the preset buttons (100 g, 150 g, etc.) for quick entry. Click "Calculate Sodium" to see the total sodium content in milligrams, along with a breakdown showing the fruit name, serving weight, and sodium density per 100 g. The result also shows what percentage of the daily recommended sodium limit (2300 mg) your serving provides. Use the Reset button to clear all fields and start a new calculation.
How It Works
The calculator uses a database of average sodium values for each fruit, sourced from the USDA FoodData Central. For each fruit, we store the sodium content in milligrams per 100 grams of edible portion. When you enter a serving size, the tool converts it to grams (if you entered ounces, it multiplies by 28.3495) and then applies the formula:
For example, if you select avocado (7 mg per 100 g) and enter a serving of 150 g, the calculation is (7 × 150) / 100 = 10.5 mg of sodium. The result is then compared to the general daily limit of 2300 mg recommended by the Dietary Guidelines for Americans. Note that individual needs may vary — people with hypertension, kidney disease, or other conditions may be advised to consume less than 1500 mg per day.
Example Calculations
Example 2: Avocado (7 mg/100g), serving 1 oz (28.35 g) → (7 × 28.35) / 100 = 1.98 mg sodium. Very low.
Example 3: Papaya (8 mg/100g), serving 250 g → (8 × 250) / 100 = 20 mg sodium. Still well within limits.

Frequently Asked Questions
Q: Which fruit has the highest sodium?
A: Among the fruits in our database, cantaloupe has the highest sodium content at 16 mg per 100 g, followed by papaya (8 mg) and avocado (7 mg). Most other fruits contain 0–3 mg per 100 g.
Q: Can fruit sodium add up significantly in a day?
A: Generally no. Even if you ate 500 g of cantaloupe (the highest-sodium fruit), you'd get only 80 mg of sodium — about 3.5% of the daily limit. Fruit sodium is negligible compared to processed foods, but it's still worth tracking if you're on a very strict low-sodium diet.
Q: Is the sodium in fruit a concern for kidney patients?
A: For most kidney patients, the bigger concern is potassium, not sodium, in fruits. However, some fruits like avocado and cantaloupe are moderate in both. Always consult your dietitian for personalized advice.
Q: Where do the sodium values come from?
A: Values are derived from the USDA FoodData Central database, which provides standardized nutritional profiles for thousands of foods. For the most accurate and up-to-date information, you can visit the USDA FoodData Central website.
