Health benefits

The main health benefits of consuming watercress are:

1. Preventing diabetes

Because of its high fiber content, watercress helps to regulate blood sugar levels. This can prevent insulin resistance and diabetes, as well as manage blood sugar levels in those who already have diabetes.

2. Strengthening bones

Watercress is rich in vitamin K, a vitamin that is essential for the bone formation and strengthening. It can prevent osteoporosis and conditions such as falls and fractures. Read more about vitamin K and how it can benefit your health.

Watercress also has great amounts of calcium, a mineral that also plays role in bone formation and overall bone health.

3. Preventing cancer

Watercress helps to prevent some types of cancer, such as pancreatic, breast or colon cancer, because it contains great amounts of flavonoids, isothiocyanates and glucosinolates. These are bioactive compounds with powerful antioxidant action that fight free radicals and prevent the growth and spread of cancer cells.

4. Preventing premature aging

As it is a vegetable rich in vitamin C, an important vitamin for the production and absorption of collagen, watercress helps maintain skin elasticity, preventing wrinkles and premature aging.

Watercress is also rich in glucosinolates, which are bioactive compounds with powerful antioxidant action that fight free radicals, one of those responsible for damage to healthy skin cells.

5. Promoting eye health

Watercress contains excellent amounts of lutein and zeaxanthin. These are carotenoids typically found in the eyes that help to fight free radicals and protect the retina. These compounds are important for maintaining eye health and preventing conditions such as macular degeneration and cataracts associated with age.

6. Preventing cardiovascular diseases

Due to its fiber content, watercress helps reduce fat absorption in the gut, which can promote optimal cholesterol and triglyceride levels in the blood. This can prevent diseases such as atherosclerosis, heart attack, high blood pressure and fatty liver.

7. Strengthening the immune system

Watercress is rich in vitamin C, vitamin A and flavonoids, which are compounds with antioxidant and anti-inflammatory action. It can strengthen the immune system and help to fight viruses, bacteria and fungi that cause coughs, allergies, bronchitis, sinusitis and the flu. 

8. Fighting constipation

Because it contains excellent amounts of fiber, watercress promotes water absorption in the gut. This can make stools softer and promote bowel movements, to help combat constipation.

9. Preventing bleeding

Vitamin K is naturally found in watercress in high quantities. It is an essential nutrient for maintaining normal blood clotting and preventing excessive bleeding with cuts and fractures.

10. Promoting weight loss

Watercress can help to promote weight loss, because it is a source of fiber that helps keep you full. This can help to reduce overeating throughout the day.

Furthermore, watercress is low in fat and calories, making it a great option to include in weight loss diets.

How to consume

Watercress can be consumed raw and added in salads, dips and juices, or cooked in stir-fries, stews, soups, omelets and rice.

Cooked watercress contains a higher level of carotenoids when compared to the raw version. However, antioxidant compounds such as glucosinolates and flavonoids are generally lost when over-cooked, which is why it should be avoided.

Watercress can also be used in teas or syrups to help treat phlegm or coughs.

  • Watercress syrup: Blend 250 ml of pure watercress juice with 1 cup of honey, then pour in a pan and boil over low heat, until it has a viscous texture. After cooling, add 5 drops of propolis. Take 1 tablespoon of this syrup, 3 times a day, until phlegm improves.
  • Watercress tea: Add 1/2 cup of chopped watercress leaves and stems to 150 ml of boiling water, cover and let the mixture infuse for 5 to 10 minutes. Strain, sweeten with 1 tablespoon of honey and drink 2 to 3 cups of this tea a day until your cough and phlegm improve.

Watercress can also be used to prepare a homemade syrup with turnip, pineapple and beetroot, which can help to reduce the symptoms of bronchitis and coughing. 

Contraindications for use

Excessive intake of watercress can increase the risk of miscarriage and, therefore, pregnant women should not consume this vegetable in the form of teas or syrups.

Furthermore, watercress can interfere with the action of some medications, such as warfarin, lithium and chlorzoxazone. Therefore, you should speak to your doctor before taking watercress, especially if you are already taking medication.
