Caper Nutrition: Breaking Down the Macros
Capers are the unripened, pickled flower buds of the caper bush (Capparis spinosa). They are valued for their intense, briny, and lemony flavor, which makes a small amount go a long way. This is fortunate for low-carb dieters, as their nutritional profile is very favorable when consumed in typical serving sizes.
Carbohydrate and Calorie Count
A standard one-tablespoon (about 9 grams) serving of drained, canned capers contains only about 2 calories and less than 1 gram of total carbohydrates. More specifically, the total carbohydrate count is approximately 0.4g, with dietary fiber accounting for about 0.3g. This results in a minimal net carb count of just 0.1g per tablespoon, a negligible amount for those monitoring their carbohydrate intake.
The Role of Sodium in Capers
While the carb count is impressively low, the sodium content is significantly high due to the brining or salting process used for preservation. A single tablespoon can contain a substantial amount of the daily recommended intake for sodium, with figures ranging from 200mg to over 250mg depending on the brand and how they were prepared.
To reduce sodium intake from capers:
- Rinse them: A quick rinse under cold water can wash off a significant portion of the surface salt.
- Soak them: For a more thorough reduction, soaking them in water for a few hours in the refrigerator can draw out more salt.
- Use sparingly: Since they are potent in flavor, a little goes a long way, naturally limiting your sodium exposure.
Health Benefits of Adding Capers to Your Diet
Beyond their culinary uses, capers offer some nutritional benefits, even in small quantities. Here are a few key advantages:
- Rich in Antioxidants: Capers contain powerful antioxidants, such as quercetin and rutin, which help fight harmful free radicals and may reduce inflammation.
- Source of Vitamin K: They provide a small but beneficial amount of vitamin K, an essential nutrient for blood clotting and bone health.
- Mineral Content: Capers also contain trace amounts of other minerals, including copper, iron, and magnesium.
- Potential Blood Sugar Support: Some studies have suggested that compounds in capers may help with blood sugar management by improving glucose uptake in tissues. However, more research is needed on the effects of normal dietary consumption.
Capers on a Keto or Low-Carb Diet
For anyone following a low-carb or ketogenic diet, capers are an excellent seasoning option. They provide a powerful burst of flavor without adding unwanted carbs or calories, which is a key strategy for maintaining ketosis.
How to Incorporate Capers into Low-Carb Meals
- Classic Chicken Piccata: Create a keto-friendly version by using a creamy, lemon-caper sauce over baked or pan-seared chicken instead of breading and pasta.
- Seafood Enhancer: Sprinkle capers over grilled salmon, white fish, or in seafood salads. The salty, tangy flavor pairs perfectly with fatty fish.
- Keto Tartar Sauce: Mix finely chopped capers with mayonnaise, lemon juice, and herbs for a delicious, low-carb tartar sauce to serve with fish.
- Salad and Dressing Topping: Add them to salads with greens and low-carb vegetables, or mix them into a vinaigrette to add a sharp, salty contrast.
- Garnish: Use fried capers as a crispy, salty garnish for main dishes.
