Watercress

What is the calorie count in watercress?

The next time you order a sandwich or a salad, don't be shy about piling on these peppery greens. You could eat a pound of watercress and take in a meager 53 calories. But don't let its lack of calories fool you; it's loaded with vitamins A, C and K. A study in The American Journal of Clinical Nutrition also found that eating 3 ounces daily increases levels of the cancer-fighting antioxidants lutein and beta-carotene.
