Rocket, also known as arugula, is a peppery, nutrient-dense leafy green that adds a distinctive flavour to salads and other dishes. As a cruciferous vegetable, it is celebrated for its health benefits far beyond its low-calorie count, which is particularly evident in small serving sizes like 15g. This comprehensive guide will break down the exact calorie count and explore the full nutritional profile of this beneficial vegetable.
The Low-Calorie Count of 15g of Rocket
For those managing their calorie intake, understanding the energy content of ingredients is crucial. For a 15g portion of rocket, the calorie count is extremely low. Based on nutritional information from several sources, the figure is typically between 3 and 4 calories. This makes it a fantastic option for adding volume, flavour, and nutrients to your meals without significantly increasing the energy density.
To put this into perspective, 100g of rocket contains around 22–25 calories. By simple calculation, a 15g serving would contain approximately 15% of that amount, confirming the minimal calorie contribution of a small handful of rocket.
Macronutrient Breakdown for 15g of Rocket
While the calorie count is minimal, it's important to understand where those few calories come from. Rocket is predominantly water, and the small amount of energy it provides comes from its minor content of carbohydrates, protein, and fat. For a 15g serving, the nutritional breakdown is as follows:

This composition shows why rocket is a dietary powerhouse: it delivers essential nutrients while remaining incredibly low in energy.
Comparison of Leafy Greens: Rocket vs. Other Common Options
To highlight how low the calorie count is, let's compare a 15g portion of rocket to a similar-sized serving of other popular salad greens. The table below illustrates the approximate calorie content based on a 15g serving size, showing that rocket is on par with, or even lower than, many alternatives.
