Calorie Count for 1 Tablespoon of Olives
The exact calorie count for 1 tablespoon of olives can vary slightly depending on the type and size. For ripe, canned olives, a tablespoon (around 8.4 grams) contains approximately 9.7 to 10 calories. A tablespoon of canned green olives, which may contain slightly more water and different fat content, measures around 12 calories. This minor difference highlights how ripeness and processing impact the nutritional profile. The calories are primarily derived from the olive's healthy fat content, specifically monounsaturated fatty acids like oleic acid.
Nutritional Composition of Olives
Beyond just calories, olives are packed with beneficial nutrients. They contain healthy fats, are relatively low in carbohydrates, and provide fiber and antioxidants. The majority of the fat is monounsaturated, which is a key component of the heart-healthy Mediterranean diet.
- Fat: Olives are an unusual fruit due to their high fat content, with 11-15% fat by weight, most of which is oleic acid. This monounsaturated fat has been linked to decreased inflammation and a lower risk of heart disease.
- Carbohydrates and Fiber: Olives are a low-carb fruit, with fiber making up a significant portion of their carbohydrate content. This contributes to a low net digestible carb count.
- Vitamins and Minerals: Olives are a good source of several vitamins and minerals, including vitamin E, iron (especially black olives), and copper. They also contain calcium and sodium, which is added during the brining process.
How Ripeness and Processing Affect Calories
The maturation process directly impacts an olive's nutritional makeup. Green olives are unripe, while black olives have ripened fully on the tree. As the fruit ripens, its water content decreases and its oil content increases, leading to a higher calorie density in black olives compared to green ones. Processing methods also play a role, as olives are cured in brine or other solutions, which significantly affects their sodium levels.
- Green Olives: Picked earlier, they have a lower fat content and fewer calories per 100 grams than their black counterparts. They are often crisp with a slightly bitter, fruity flavor.
- Black Olives: Harvested later, their higher fat content makes them more calorically dense, but also richer in monounsaturated fats and certain antioxidants.

| Carbohydrates | ~0.3 g | ~0.5 g |
| Fiber | ~0.3 g | ~0.3 g |
| Sodium | ~131 mg | ~73 mg |
| Iron | Low | Slightly Higher |
| Polyphenols (Antioxidants) | High Levels | Also High Levels, but different profile |
Incorporating Olives into Your Diet
Since 1 tablespoon of olives is a small number of calories, they can be easily added to various meals for flavor and nutritional benefits. They work well in salads, pasta dishes, and sandwiches. Their healthy fats and fiber can also contribute to satiety, helping you feel full longer. However, because they are typically high in sodium from the curing process, it's important to be mindful of portion sizes, especially for those watching their salt intake. A moderate daily intake of 5 to 10 olives is generally recommended.
Conclusion
One tablespoon of olives is a very low-calorie addition to your diet, typically ranging from 10 to 12 calories, with the exact number depending on whether they are green or black. These calories are not empty, but come from heart-healthy monounsaturated fats, along with fiber, antioxidants, and minerals. While enjoying olives, remember to be mindful of their sodium content. They offer a delicious and nutritious way to boost the flavor of your meals while providing significant health benefits, making them a smart choice for a balanced diet.
