                                According to the Centers for Disease Control and Prevention (CDC), watercress is the only food to receive a perfect nutrient-density score of 100. This makes the peppery, leafy green a prime contender for the title of what fruit or vegetable has the most nutritional value, outperforming many common rivals.
