Green leafy vegetables have always been celebrated for their nutritional value and health benefits. Spinach, broccoli, kale, and lettuce have long been regarded as dietary powerhouses. However, the American health agency CDC (Centers for Disease Control and Prevention) claims that there is a green vegetable that might surpass the nutritional prowess of spinach, broccoli, and kale. Recently, watercress has been placed at the top of the list of healthy vegetables by the CDC. This agency evaluates the nutritional value of fruits and vegetables based on essential vitamins and minerals.
According to a report, watercress is the only vegetable that has scored a perfect 100. Following watercress, spinach, Swiss chard, and beets are ranked in the list. Watercress outperforms lettuce in terms of vitamin A, potassium, and vitamin C, surpassing even oranges in vitamin C content. Due to its rich nutrient profile, it is believed to offer protection against cancer, heart diseases, and support immune health. Watercress has been used for centuries in various culinary traditions, including ancient Greek, Persian, and Roman cuisines. In India, it is utilized both as a leafy green and a medicinal herb.
Beyond culinary use, watercress has been employed in Europe and Asia for centuries to create herbal remedies. Many people do not consider watercress a typical vegetable because it grows in fresh water sources like rivers and ponds and belongs to the Brassicaceae family, which includes cabbage, kale, and radishes. In some regions, watercress is even considered a weed due to its propensity to thrive in wet environments. It can be challenging to find watercress in regular grocery stores, but it is readily available in health food stores and online retailers.
