Nearly all fresh fruits are naturally very low in sodium, with most containing 0 mg per serving. Fruits are one of the lowest-sodium food groups you can eat, making them an easy choice if you’re watching your salt intake. The American Heart Association recommends no more than 2,300 mg of sodium per day, with an ideal target of 1,500 mg for most adults, and swapping processed snacks for whole fruit is one of the simplest ways to stay within those limits.
Most Fresh Fruits Contain Zero Sodium
According to FDA nutrition data, many of the most popular fruits register at 0 mg of sodium per serving. That includes apples, bananas, oranges, strawberries, blueberries, grapes, peaches, pears, and watermelon. These aren’t just “low sodium” by loose standards. Under FDA labeling rules, a food qualifies as “very low sodium” at 35 mg or less per serving and “low sodium” at 140 mg or less. Fresh fruits don’t just clear those bars, they essentially have no sodium at all.
This holds true across a wide variety of fruits. Whether you’re eating tropical options like mangoes and pineapple, stone fruits like plums and nectarines, or berries of any kind, you’re getting negligible sodium. The naturally occurring sodium in most fresh fruit is so small it rounds to zero on a nutrition label.
A Few Fruits With Slightly More Sodium
Some fruits do contain trace amounts of sodium, though the levels are still very low compared to most other foods. Cantaloupe has about 26 mg per cup, and honeydew melon comes in around 31 mg per cup. These are still well under the 140 mg threshold for “low sodium” labeling, but they’re worth noting if you’re on a very strict sodium restriction.
The bigger concern is processed and packaged fruit. Canned fruits packed in syrup or water often pick up sodium during processing. Canned plums in heavy syrup can contain around 49 mg per cup, and canned peaches and pears typically have 13 to 16 mg per cup. Dried fruits can also be higher: dried apples treated with sulfur contain about 28 mg per five-ring serving, and sun-dried tomatoes (technically a fruit) pack roughly 42 mg in a single piece. If sodium is a concern, fresh or frozen fruit without added ingredients is your best option.
Why Fruits Help With Blood Pressure
Fruits do more than just avoid adding sodium to your diet. Many are rich in potassium, which actively helps your body flush out excess sodium through your kidneys. A medium banana provides about 450 mg of potassium, an orange delivers around 250 mg, and a cup of cantaloupe has roughly 473 mg.
The ratio of sodium to potassium in your diet matters for blood pressure. Research in adults over 40 found that a higher sodium-to-potassium ratio was associated with increases in both systolic and diastolic blood pressure. People in the highest ratio group had systolic readings about 2 mmHg higher than those in the lowest group. That may sound small, but across a population, even modest blood pressure shifts affect heart disease risk. Eating potassium-rich, sodium-free fruits tips this ratio in a favorable direction.
How Many Servings to Aim For
The DASH eating plan, which was specifically designed to lower blood pressure, recommends 4 to 5 servings of fruit per day. One serving is roughly one medium piece of whole fruit, half a cup of chopped fruit, or a quarter cup of dried fruit. Hitting that target gives you a significant potassium boost while contributing essentially zero sodium to your daily intake.
For context, the average American consumes over 3,400 mg of sodium per day, well above the recommended ceiling. Cutting back by even 1,000 mg a day can measurably improve blood pressure and heart health. Replacing salty snacks like chips, crackers, or processed cheese with fresh fruit is one of the most straightforward swaps you can make. You’re not just removing sodium; you’re adding potassium, fiber, and other nutrients that support cardiovascular health.

Fresh vs. Canned vs. Dried
Fresh fruit is always your lowest-sodium option. Frozen fruit without added sauces or syrups is essentially equivalent, since the freezing process doesn’t introduce sodium. Canned fruit varies depending on the packing liquid. Water-packed options tend to have less sodium than syrup-packed versions, but both can contain more than their fresh counterparts. If you buy canned, check the label and look for “no salt added” varieties.
Dried fruit is a mixed bag. Plain dried fruit like raisins and dried cranberries stays low in sodium, but some commercially dried fruits are treated with preservatives that add small amounts. Sun-dried tomatoes are a notable outlier, since the drying process concentrates their naturally occurring sodium. One small piece of sun-dried tomato contains about 42 mg, which adds up quickly if you eat several.
The bottom line is simple: fresh fruit is one of the most reliably low-sodium foods available. You don’t need to seek out specific varieties or worry about hidden sodium. Just reach for whole, unprocessed fruit and you’re making one of the easiest low-sodium choices in your entire diet.
