Watercress: A Nutrient-Dense, Low-Calorie Leafy Green
Watercress (Nasturtium officinale) is a leafy green often celebrated as a superfood due to its incredible nutrient density. Despite its robust flavor, it contains a remarkably small number of calories, making it a cornerstone for those focused on weight management and overall health. Its high water content, combined with essential vitamins and minerals, allows you to consume a generous portion without significantly impacting your daily calorie count.
The Nutritional Breakdown: Is Watercress High in Calories?
To put it simply, no, watercress is not high in calories. A standard cup of chopped watercress, weighing around 34 grams, contains less than 4 calories. Even a more significant portion of 100 grams (about 3.5 ounces) contains only about 11 calories. This minimal caloric load makes it an ideal food for anyone on a calorie-controlled diet. The bulk of its content is water, which accounts for about 95% of its weight, with minimal carbohydrates and fats.
Beyond its low-calorie nature, watercress provides a rich source of vital nutrients. These include:
- Vitamin K: A single cup can provide over 100% of the Reference Daily Intake (RDI), which is crucial for blood clotting and bone health.
- Vitamin C: An excellent source of this antioxidant, which supports immune function and collagen production.
- Vitamin A: Rich in beta-carotene, which is essential for vision and skin health.
- Antioxidants: Watercress contains powerful antioxidants, such as beta-carotene, lutein, and zeaxanthin, which help protect against cellular damage from free radicals and may lower the risk of chronic diseases.
Watercress vs. Other Leafy Greens: A Calorie Comparison
To illustrate just how low in calories watercress is, it's helpful to compare it to other common leafy greens. While all greens are generally low in calories, watercress often comes out on top for packing the most nutrients into the fewest calories. The Centers for Disease Control and Prevention even ranked watercress as the number one 'Powerhouse Fruit and Vegetable' for its nutrient density.
| Nutrient (Per 100g raw) | Watercress | Spinach | Kale |
|---|---|---|---|
| Calories | 11 kcal | ~23 kcal | ~35 kcal |
| Protein | 2.3 g | ~2.9 g | ~3.3 g |
| Carbohydrates | 1.3 g | ~3.6 g | ~4.4 g |
| Vitamin K (% DV) | 208% | 121% (men) / 161% (women) | 684% |
| Vitamin C (% DV) | 48% | 34% | 133% |
Note: Nutritional data can vary slightly depending on the source and specific plant batch.
As the table shows, watercress offers a very low-calorie and low-carbohydrate profile, while still providing significant percentages of key vitamins, especially Vitamin K. This balance makes it a highly efficient food source for those seeking to maximize nutritional intake on a reduced-calorie plan.

Does Cooking Watercress Change its Calorie Count?
Cooking watercress does not significantly change its low-calorie nature. However, certain nutrients, like Vitamin C, are sensitive to heat and may be slightly reduced. Cooking often causes wilting, which can make a larger volume of watercress seem smaller, but the calorie content per gram remains very low.
How Much Watercress Should I Eat for the Best Results?
While there's no set amount, regularly incorporating watercress into your diet is beneficial. A good target is one to two cups per day, added to salads, soups, or smoothies, to enjoy a nutrient boost without adding significant calories.
Is Watercress High in Fat or Sodium?

Can Watercress Help with Hydration?
Yes. Watercress is approximately 95% water. Including it in your diet helps contribute to your daily fluid intake, assisting with overall hydration.
What Makes Watercress Taste Peppery?
The peppery flavor of watercress comes from natural compounds called glucosinolates. When the plant is chewed or cut, these compounds release isothiocyanates, which are responsible for its distinctive taste.
What are Some Common Concerns with Watercress?
One concern with watercress, particularly wild-foraged watercress, is the potential for contamination from heavy metals or bacteria if grown in polluted water. It's recommended to purchase watercress from reputable hydroponic growers. Also, its high Vitamin K content can interfere with blood-thinning medication.
