Considered one of the oldest leaves consumed by humans, the watercress is dark green and has a mild peppery flavour with a bitter tang. It belongs to the family of exotic cabbage, broccoli and kale. The herb is gaining its position amongst the superfoods because of its high nutrient content.
The watercress leaf has a spicy taste. Therefore, it is generally used as garnish over salads, in sandwiches or diluted with vinegar to create a blend of Italian flavours. You can eat raw watercress. In addition, each part of it is edible, including leaf, stem, and flower. Although its roots might not taste bad, you should stay away from its consumption.
One hundred grams of watercress contains:
Watercress is rich in lutein and zeaxanthin; these are carotenoids with antioxidant properties. According to research, these two carotenoids are essential components for eye health. They constitute the primary pigments found in the yellow spot, which protect the macula from damage by blue light, improve visual acuity, and scavenge harmful reactive oxygen species. In addition, they help reduce the risk of age-related macular degeneration (AMD) and cataracts.
Lutein and zeaxanthin also show properties that help lower the risk of developing age-related macular degeneration and cataracts. In addition, the vitamin C content in watercress also helps to reduce the chances of developing cataracts.
Watercress contains incredibly high amounts of vitamin C. It has up to 15mg of vitamin C per cup, about 20% of recommended daily intake (RDI). Several studies suggest that vitamin C is a micronutrient that supports various cellular functions of the immune system. In addition, it helps the skin barrier against pathogens.
Vitamin C also acts as an antioxidant and helps to reduce oxidative stress. The oxidative stress by free radicals binds with the free-flowing oxygen in the body and prevents the healthy cells from getting fresh oxygen. Antioxidants eliminate these free radicals and prevent oxidative stress.
Some essential minerals necessary for bone health are calcium, potassium, magnesium and phosphorus. Calcium is the building block to the entire skeletal structure. However, vitamin K and potassium also play an essential role in maintaining bone health.
Vitamin K is a part of a protein called osteocalcin, which makes up the bone tissue and regulates bone turnover. According to a study, people with the highest intake of vitamin K were 35% less prone to expecting a hip fracture than people with poor vitamin K intake.
One of the many watercress’s benefits is that it aids in reducing cholesterol levels. Including watercress in your diet can reduce triglyceride levels significantly. High triglyceride levels are responsible for increased cholesterol.
According to research, watercress also reduces low-density lipoproteins (LDLs), which is bad cholesterol and increases high-density lipoproteins (HDLs), the good cholesterol.
Like any other leafy vegetable, watercress contains naturally occurring dietary nitrates. Nitric oxide is a crucial compound in regulating vascular functions. A study demonstrates that people who consume nitrate supplements or nitrate dense foods have low blood pressure, suggesting that nitrate can positively control hypertension.
Watercress is also rich in potassium which can help lower blood pressure by balancing out the effects of sodium. It also relaxes the blood vessels’ walls and allows easy blood flow without restriction or cramping.
Watercress contains high levels of phytochemicals. These phytochemicals reduce the risk of developing cancer. As per studies, compounds like glucosinolates in watercress have anticancer effects. In addition, it contains isothiocyanates like sulforaphane and phenethyl isothiocyanate. They inactivate carcinogenic chemicals and block the uncontrolled growth of tumours. As a result, they protect the healthy cells against cancer.
Watercress is full of antioxidant compounds that help to protect healthy cells from damage caused by free radicals. It can also help to reverse some of the already caused damage.
Free radicals cause oxidative stress, leading to many chronic illnesses, like diabetes, cardiovascular disorders and even cancer. Watercress has over 40 flavonoids (antioxidants) and can neutralise free radicals.
Watercress contains high amounts of dietary nitrates. Nitrates help relax the blood vessels and increase the amount of nitric oxide in the blood. As per studies, nitric oxide (NO) may improve exercise performance. In addition, dietary nitrates can help lower resting blood pressure. As a result, it reduces the amount of oxygen you need during exercise. Hence, it may increase exercise tolerance.
Watercress is one of the most nutrient-dense foods. It has benefits for weight management and weight loss as well. One cup of watercress has minimal calories but is full of essential nutrients like vitamins and micronutrients. Low-calorie vegetables are highly effective for weight loss, and you should add them to your diet. Watercress is also very versatile, so it is easy to incorporate it into your regular dishes.
Watercress is rich in folate. As per research, It is an essential nutrient for pregnant women. Folate ensures the healthy development of the foetus or the embryo. Folate deficiency can lead to abnormalities in the foetus and even cause complications for the mother. Having a folate-rich diet can also reduce the chances of developing anaemia.
Watercress has some medicinal usage. However, there is not enough evidence or research to support the effectiveness of watercress for these uses. But you can use it to calm down specific symptoms related to cough, bronchitis, inflammation, flu and constipation.
Watercress is majorly used in cooking and has a bitter-tangy taste to it. However, a common way to use watercress can be a food dressing.
