Dill pickles are one of the lowest-calorie foods you can eat, with a single spear coming in at roughly 5 calories. Even a whole medium dill pickle typically lands between 10 and 15 calories. Sweet pickles, however, are a completely different story, packing around seven times more calories due to added sugar.
Dill Pickles vs. Sweet Pickles
The calorie gap between pickle types is dramatic. Per 100 grams (about 3.5 ounces), dill pickles contain just 12 calories with only 1 gram of sugar. Sweet pickles hit 90 calories for the same weight, with 18 grams of sugar. That sugar comes from the sweetened brine they’re packed in, not from the cucumber itself.
A standard kosher dill pickle spear (about 28 grams) contains 5 calories. You could eat an entire jar of dill spears and still consume fewer calories than a single banana. Bread-and-butter pickles fall somewhere between dill and sweet, since their brine contains sugar but less than a full sweet pickle recipe. If you’re reaching for pickles as a low-calorie snack, stick with dill or sour varieties.
Why Pickles Are So Low in Calories
Cucumbers are about 95% water, and brining doesn’t change that much. The pickling liquid, whether vinegar or salt brine, adds virtually no calories on its own. The cucumber’s flesh contributes a small amount of natural carbohydrate and fiber, but there’s simply not much caloric material in the vegetable to begin with. This makes dill pickles one of the rare foods where you can eat a satisfying portion without meaningfully affecting your daily calorie intake.
The vinegar in pickles may also play a small role in appetite. Acetic acid, the main component in vinegar, has been linked to reduced food intake in animal studies. Research published in Scientific Reports found that vinegar consumption led to significant suppression of food intake in mice on a high-fat diet. Human evidence is more limited, but the combination of crunch, strong flavor, and almost zero calories makes pickles a practical snack when you’re trying to eat less.
The Sodium Trade-Off
The catch with pickles is salt. A single dill spear contains 150 to 300 milligrams of sodium. Eat three or four spears and you’ve consumed up to 1,200 milligrams, which is more than half the World Health Organization’s recommended limit of 2,000 milligrams per day. If you’re eating pickles regularly, that sodium adds up fast.
For most healthy people, the occasional pickle habit isn’t a concern. Research from the Journal of Athletic Training found that small quantities of pickle juice didn’t meaningfully raise blood sodium levels or cause dehydration in resting adults. But if you have high blood pressure, kidney issues, or you’re sensitive to sodium, a few spears a day could push your intake well beyond recommended levels. Low-sodium pickle brands are widely available and typically cut the salt content by 30 to 50%.
Fermented vs. Vinegar Pickles
Most pickles on grocery store shelves are made with vinegar and then pasteurized for shelf stability. These contain no live beneficial bacteria. Fermented pickles, made with salt brine and no vinegar, develop natural probiotics during the culturing process. The calorie count is essentially the same for both types, but the gut health benefits differ significantly.
If you want the probiotic benefit, look for pickles stored in the refrigerated section with labels that mention fermentation and no pasteurization. Heat processing, including the hot water bath used for canning, kills the live cultures. Homemade pickles fermented in salt brine and kept cold will retain their beneficial bacteria. Vinegar-based pickles, even homemade ones, won’t contain meaningful probiotics unless cultures are added after the fact, which is rare.
What to Watch For on the Label
Not all pickles are as simple as cucumbers, water, vinegar, and salt. Some commercial brands add sugar to dill pickles, which can bump up the calorie count beyond what you’d expect. Others include food dyes like Yellow No. 5 to give the pickles a brighter green color. These additives don’t affect the calorie count, but they’re worth knowing about if you prefer to avoid artificial ingredients.
The fastest way to gauge calories is to check whether sugar appears in the ingredient list. If it does, look at the nutrition label for total sugars per serving. A dill pickle with zero added sugar will almost always fall in the 5-calorie-per-spear range. Any pickle labeled “sweet,” “bread and butter,” or “candied” will be significantly higher, and the sugar content is usually the reason.
