                                According to a study by the Centers for Disease Control and Prevention (CDC), watercress topped the charts as the most nutrient-dense food per calorie, making a strong case for it being the most nutritious raw vegetable. While a definitive single "best" vegetable is subjective, watercress leads in nutrient concentration, followed closely by other greens like kale and spinach.
