The Surprising Nutritional Profile of Jarred Capers
While most are consumed in small amounts as a seasoning, the little green caper buds offer some notable nutrients. A single tablespoon contains only a couple of calories but is surprisingly rich in certain compounds that benefit health.
Key Nutrients and Plant Compounds
- Antioxidants: Capers are packed with powerful plant-based antioxidants, primarily flavonoids like quercetin and rutin. Quercetin has been linked to anti-inflammatory effects and potential benefits for brain and heart health by modulating potassium ion channels.
- Vitamins: Capers provide a small but beneficial amount of vitamin K, essential for blood clotting and bone health. They also contain small amounts of vitamin A, E, and C.
- Minerals: You can find traces of minerals such as copper, iron, and magnesium. Copper, in particular, plays a role in iron metabolism and energy production.
The Major Downside: High Sodium
The most significant nutritional consideration for jarred capers is their exceptionally high sodium content. The curing process, whether in brine or salt, is what gives them their characteristic salty flavor, but it also skyrockets their sodium levels. A typical tablespoon of drained, canned capers can contain over 200mg of sodium, roughly 9% of the recommended daily value for healthy adults.
For those with high blood pressure, kidney disease, or other conditions requiring a low-sodium diet, this can be a serious concern. Excessive sodium intake is a major risk factor for heart disease and stroke, and has been linked to other health issues.
Comparison: Cured in Brine vs. Dry-Salted Capers
The method of curing can affect both the flavor profile and sodium level of the final product. Most capers found in grocery stores are brined, but some specialty markets offer dry-salt cured versions.
| Feature | Brine-Cured Capers | Dry-Salted Capers |
|---|---|---|
| Appearance | Pickled green buds in a vinegar-based liquid. | Gray-green buds coated in salt crystals. |
| Flavor | Sharply tangy and salty, with a piquant, bright finish. | More intensely salty, with a floral, aromatic undertone. |
| Texture | Softer and more yielding due to the pickling process. | Firmer, with a more concentrated chew. |
| Sodium Level | Very high, but rinsing can reduce it significantly. | Extremely high, requiring thorough rinsing before use. |
| Preparation | Often rinsed briefly before adding to dishes. | Must be rinsed extensively or soaked to remove excess salt. |
Practical Tips for Enjoying Capers Responsibly
If you love the flavor of capers but are mindful of your sodium intake, you don't have to give them up entirely. Here are some smart strategies:
- Rinse thoroughly: Before using, place capers in a fine-mesh strainer and rinse under cold water for 30-60 seconds. This simple step can significantly decrease their sodium content.
- Soak and rinse: For dry-salted capers, or to remove even more sodium from brined ones, soak them in a bowl of fresh water for 5-10 minutes, then rinse again before using.
- Use them as a finishing touch: Add capers at the end of cooking to maximize their punchy flavor without needing additional salt. Their briny taste allows you to use less salt overall in a recipe.
- Balance flavors: Pair capers with fresh, acidic ingredients like lemon juice or tomatoes to balance the saltiness. Their unique flavor can serve as a substitute for salt in many recipes.
- Portion control: Treat capers as a garnish rather than a main ingredient. A little goes a long way, and enjoying them in small, controlled portions is key to keeping sodium in check.
Conclusion
So, are jarred capers good for you? The answer is nuanced. While they offer a wealth of antioxidants like rutin and quercetin, their preparation in brine or salt makes them exceptionally high in sodium. Enjoying jarred capers is a matter of moderation and preparation. By rinsing them thoroughly before use, you can harness their unique flavor and nutritional benefits while keeping the sodium concerns at bay. For most people, a sprinkle of rinsed capers is a perfectly healthy addition to a balanced, flavorful diet.

How to Choose and Store Jarred Capers
- Look for clarity: When buying brined capers, check that the liquid in the jar is clear, not cloudy, which can indicate poor quality.
- Consider caper size: Capers are graded by size, with the smallest (nonpareilles) being the most prized for their delicate texture. Larger capers are more acidic and can be used in cooked sauces.
- Refrigerate after opening: Once opened, keep the jar of capers tightly sealed and refrigerated to maintain freshness and flavor.
Quick and Easy Ways to Use Capers
- Pasta: Toss with lemon, garlic, and olive oil for a simple, vibrant pasta sauce.
- Fish: Add to pan-seared fish with a butter and lemon sauce.
- Salads: Sprinkle over fresh salads for a briny pop of flavor.
- Sauces: Stir into homemade or store-bought mayonnaise to create a tartare sauce.
The Health Benefits of Moderation
Enjoying a variety of healthful foods is a cornerstone of good nutrition. For capers, this means embracing the flavor they add without relying on them for a major nutritional boost. Their potent antioxidants are a bonus, but their primary role is culinary, enhancing dishes with a bright, briny kick that allows you to reduce your reliance on salt from other sources.
By being mindful of preparation and portion size, you can confidently include jarred capers as a valuable part of your diet. Think of them as a flavor-packed garnish, rather than a significant source of daily nutrients, and savor the unique taste they bring to your cooking.
