Most people do not realize that watercress (nasturtium officinale) is one of our most nutritious vegetables. It is one of the oldest green leafy vegetables known to man. It is a hardy perennial plant and semi-aquatic, is found in it's wild state on the banks of rivers in many parts of Europe and Asia. Both the Roman and Ancient Greeks held the plant in high regard.
Watercress is an excellent source of the beta-carotene (converts to vitamin A in the body), vitamins B1, B6, C, E and K. It is also a good source of dietary fibre, folic acid (folate), iodine, phosphorous, selenium, potassium, iron, calcium and copper. On top of that it's carotenoid content of lutein and zeaxanthin and the flavornoid quercetin make it truly a superfood. Gram for gram it has more antioxidants than broccoli and tomatoes, more vitamin C than oranges, more absorbable iron than spinach, more potassium than bananas, more quercetin than broccoli and even more calcium than milk.
Therefore, when eaten, watercress benefits our whole body:
Lutein, zeaxanthin and zinc for the eyes.
Iron, zinc and vitamin A for hair and nails.
Iodine for the thyroid.
Folic acid, iron, vitamin B6 & C for the blood.
Calcium, magnesium, phosphorous, manganese and vitamins for the bones.
Vitamins A, E & C for the skin.
Carotenes, zinc, vitamins A, C & E for the immune system.
Vitamin K assists in blood clotting when injured.
Externally fresh watercress juice has been used to stimulate thick hair growth, to heal acne and eczema, and to lighten freckles.
Another watercress health plus is that it contains high levels of a type of glucosinolate, called phenylethyl isothiocyanate (PEITC), which is thought to be a main factor in cancer prevention. Currently a clinical study is being done at the University of Southampton, England in which it is investigating watercress’s potential ability to suppress breast cancer cell development. The results are due to be announced on 2 March 2010. This follows previous research carried out by the University of Ulster, Coleraine, and published in the American Journal of Clinical Nutrition in February 2007 which found that watercress increased the ability of cells to resist DNA damage caused by free radicals and that daily intake of watercress significantly reduced levels of DNA damage found in blood cells. DNA damage is considered to be an important trigger in the early stages of cancer. For more detail, Listen to the BBC interview on 15th Feb 2007 with Professor Ian Rowland of the University of Ulster here.
When purchasing buy fresh, dark green, organic watercress. Once purchased it can be stored in a container or plastic bag for a couple of days in the vegetable drawer of the fridge. Eat as soon as possible for the best health benefits. Why not try to grow your own, either in your garden or in a container? Watercress is a wonderful addition to salads, sandwiches and vegetable juices. delicious in soups and stir fries as well.

Watercress and Barley Salad
Adapted from Whole Living
Grains make a salad more substantial. They also continue to absorb moisture as they sit, so if you've made the salad in advance, you might need to add more dressing or lemon juice to perk it up when serving. For a change of pace, try substituting 3 1/2 cups of another cooked whole grain, such as brown rice or quinoa, for the barley.
1 cup pearled barley, rinsed and drained
Coarse salt
1/3 cup fresh lemon juice
2 tsps vegan Dijon mustard
1 tsp agarve syrup or other sweetener
1/3 cup extra-virgin olive oil
Ground pepper
2 med carrots, cut into small diced pieces
1 med cucumber, peeled, halved lengthwise, seeded, and cut into medium-size diced pieces
1/2 small red onion, minced
1/4 cup minced fresh dill
1 large bunch watercress, stems trimmed, torn into bite-size pieces
1/3 cup toasted sunflower seeds
In a large pot, bring 2 quarts water to a boil over high heat. Add barley and 1/2 teaspoon salt; reduce to a simmer and cook, uncovered, until barley is tender but still chewy, about 35 minutes. Drain; rinse barley under cold running water until cool. Drain well, and transfer to a large bowl. Whisk together lemon juice, mustard, syrup, and oil in a small bowl; season with salt and pepper. Set aside. Add carrots, cucumber, red onion, dill, and dressing to large bowl with barley. Toss to combine. At serving time, add watercress and sunflower seeds; toss to combine.
