Health Benefits of Watercress

Watercress, that unassuming, slightly peppery leafy green, has the remarkable power to elevate the flavor profile of your sandwiches, salads, and even smoothies. Thriving in or around water, this green gem not only delights the palate but also serves as a gateway to a multitude of health benefits, including the reduction of cancer risks and bolstering bone health.

The illustrious journey of watercress in human consumption spans centuries, with documented evidence dating back to 1803 when Lewis and Clark took note of its presence during their iconic expedition. Even the intrepid Captain James Cook, renowned for circumnavigating the globe thrice, recognized the value of watercress, incorporating it into his sailors’ diet, potentially protecting them from the perils of scurvy—a debilitating condition caused by severe vitamin C deficiency.

Watercress, a naturally low-calorie and low-fat food, is not only a treasure trove of essential micronutrients but also harbors plant compounds that have been linked to significant health outcomes. To unveil the potential ways in which watercress might support your well-being, delve into the following five effects you may experience when making it a regular part of your diet.

1. May Reduce Cancer Risk

While watercress is celebrated for its low-calorie content and robust flavor, it boasts a lesser-known attribute—a powerful cancer-fighting compound known as phenethyl isothiocyanate (PEITC). Research has revealed that PEITC can inhibit cancer progression and deter the initial phases of cancer development.

Watercress stands out as one of the most abundant sources of PEITC, with broccoli and turnips offering alternative natural sources. Furthermore, watercress contains a significant amount of vitamin C, another micronutrient associated with cancer prevention.

2. May Support Eye Health

The influence of diet on vision health cannot be overstated. Two carotenoids, lutein and zeaxanthin, play pivotal roles in safeguarding eyes against macular degeneration—a condition that leads to central vision loss.

Watercress emerges as a natural source of both lutein and zeaxanthin, positioning it as an ideal choice for nurturing eye health.

3. May Support Immune Health

Vitamin C, a renowned immune-boosting nutrient, finds ample representation in watercress. A deficiency in vitamin C has been correlated with compromised immunity and an increased susceptibility to infections.

Additionally, watercress contains vitamin A, another vital contributor to immune health. Research suggests that a deficiency in vitamin A may impair innate immunity.

Ample evidence underscores the immune-enhancing benefits of a diet rich in vegetables, with higher vegetable intake consistently linked to improved immune function.

4. May Support Heart Health

The consumption of raw vegetables has been associated with a reduced risk of cardiovascular disease.6 Given that watercress is predominantly consumed in its raw form, it becomes an excellent choice for those seeking to boost their vegetable intake.

Watercress boasts a heart-healthy profile, characterized by low sodium and saturated fat content—two factors of utmost importance in heart-healthy nutrition. Furthermore, it contains quercetin, a compound known for its antioxidant and anti-inflammatory properties. Quercetin contributes to cardiovascular well-being by lowering blood pressure, reducing cholesterol levels, and enhancing endothelial function (blood fluidity), positioning it as a promising component in the prevention and treatment of cardiovascular diseases.

Watercress also shines due to its magnesium, calcium, and potassium content—three essential nutrients emphasized in the DASH Diet (Dietary Approaches to Stop Hypertension). Adhering to the DASH Diet has been shown to reduce cardiovascular disease risk factors.

5. May Support Bone Health

An array of factors, encompassing genetics, physical activity patterns, and even smoking habits, can profoundly affect bone health. In terms of diet, specific nutrients play a crucial role in maintaining healthy bones.

Key bone health nutrients include calcium, magnesium, vitamin C, and vitamin K—each of which finds representation in watercress. This green superstar is equipped to meet your nutritional needs and potentially promote bone formation, contributing to the preservation of strong and healthy bones.

Risks of Eating Watercress

While watercress is generally considered safe for most individuals, certain precautions should be exercised:

2. Allergies: Individuals with known allergies to watercress should refrain from its consumption.

3. Kidney Stones: Watercress contains natural substances known as oxalates, which are excreted through the kidneys. In some cases, oxalates can crystallize in the urine, leading to the formation of kidney stones. If you are prone to kidney stones, cautious consumption of watercress may be advisable.
