Watercress named world's healthiest vegetable by scientists

Watercress, a leafy green plant often found near springs and watercourses, has been declared the healthiest vegetable in the world by scientists. While attention often focuses on foods like avocado and salmon, watercress, known in Romania as brâncuță or măcriș de baltă, has outperformed all other analyzed foods in terms of nutritional value.

A study conducted by the Centers for Disease Control and Prevention (CDC) ranked watercress highest for nutrient density. Researchers analyzed over 40 plant-based foods, calculating the ratio of essential nutrients to calories. Watercress achieved a perfect score of 100, surpassing well-known healthy options such as spinach, broccoli, kale, and Chinese cabbage.

Watercress belongs to the Brassicaceae family, which includes cabbage, radish, and broccoli. It has a slightly peppery taste and a history of consumption dating back to antiquity, valued for both culinary and medicinal properties. In medieval Europe, it was used for breath freshening and natural remedies.

Nutritionally, watercress is a concentrated source of micronutrients. It contains significant amounts of vitamins A, C, E, and K, along with iron, calcium, potassium, iodine, and omega-3 fatty acids. A 100-gram serving contains only 12 calories, offering essential nutrients with minimal caloric intake. The plant also provides protein and fiber while being fat-free.
