Discovering Watercress: Why Its Nutritional Profile Stands Out
Watercress is a leafy green vegetable that has been valued for centuries, both as a culinary ingredient and for its potential health benefits. With its peppery flavor and vibrant, crisp leaves, watercress is often included in salads, sandwiches, and as a garnish. What truly makes watercress noteworthy, however, is its dense concentration of nutrients, especially given its low calorie count. In this article, we explore the nutritional breakdown of watercress, its health advantages, how to add it to your meals, tips for selection and storage, as well as important considerations for consumption.
Watercress Nutrition Breakdown (Per 100 Grams)
Macronutrient Content
Watercress is exceptionally low in calories, containing approximately 11 kcal per 100 grams. Here’s a closer look at its main macronutrients:
- Carbohydrates: Roughly 1.3 grams, with dietary fiber making up about 0.5 grams. Sugars are minimal, under 0.2 grams.
- Protein: About 2.3 grams, which is higher than many other leafy greens.
- Fat: Less than 0.5 grams, primarily unsaturated.
Key Vitamins and Minerals

- Vitamin A (as beta-carotene): Supports eye health and immune function.
- Calcium: Important for bone health; watercress provides a notable amount compared to many leafy greens.
- Potassium: Supports heart and nerve function.
- Folate: Vital for DNA synthesis and cell division, especially important during pregnancy.
Other Beneficial Compounds
Watercress contains phytochemicals such as glucosinolates and isothiocyanates, which are known for their potential role in cancer prevention. The green is also high in antioxidants that combat oxidative stress.
The Health Perks of Watercress
The impressive nutrient density of watercress is linked to several health advantages:
- Supports Bone Health: High vitamin K and calcium levels promote strong bones and may reduce the risk of osteoporosis.
- Enhances Immune Function: Abundant vitamin C and A bolster immunity and skin integrity.
- Antioxidant Properties: Carotenoids, vitamin C, and plant compounds help fight cell damage and inflammation.
- Heart Health: Potassium and antioxidants in watercress contribute to maintaining healthy blood pressure and reducing inflammation.
- Potential Cancer Protection: The glucosinolate content is being studied for its detoxifying effects and support of cellular health.
Easy Ways to Include Watercress in Your Daily Diet
Getting more watercress into your meals is simple thanks to its versatility:
- Add fresh watercress to salads for a peppery bite.
- Tuck leaves into sandwiches or wraps in place of lettuce.
- Burst flavor into omelets, stir-fries, or pasta dishes by stirring in fresh watercress at the end.
- Use as a garnish on soups, stews, or roasted vegetables to add nutrition and color.
- Pair with fruit, such as citrus, in composed salads for a refreshing and nutrient-rich mix.
Selecting and Preserving Watercress Freshness
Look for watercress with vibrant, deep green leaves and crisp stems; avoid those with yellowing or wilting. Watercress is highly perishable, so store it in the refrigerator. To prolong freshness, place the stems in a glass of water (like a bouquet) and loosely cover with a plastic bag, or keep in a perforated bag with paper towels to absorb excess moisture. Use within a few days for peak nutrition and flavor.
Considerations: Safety, Allergies, and Interactions
Watercress is considered safe for most people when eaten in typical food amounts. However, those taking anticoagulant medications (like warfarin) should monitor their vitamin K intake, as watercress is extremely rich in this vitamin. Watercress also grows in water, so ensure it is well washed to avoid contaminants. Rarely, individuals may be sensitive to cruciferous vegetables and experience digestive discomfort.
FAQs About Watercress Nutrition
Is watercress a good source of iron?
While watercress contains a modest amount of iron, it also has vitamin C, which helps improve the absorption of plant-based iron.
Does cooking watercress reduce its nutritional value?
Some vitamins, like vitamin C, may decrease with heat, but lightly cooking watercress can help break down cell walls and make certain minerals more available.
Can people with thyroid conditions eat watercress?
As a member of the cruciferous vegetable family, watercress contains goitrogens, which may interfere with thyroid function if eaten in extremely large amounts. Most people can safely enjoy watercress in moderate portions as part of a varied diet.
Is watercress suitable for low-calorie or weight management diets?
Absolutely. Watercress is very low in calories and high in water, fiber, and essential nutrients—making it an excellent choice for those managing calorie intake.
