Cilantro offers health benefits stemming from its vitamin A and vitamin K nutrients, while also containing only one calorie per serving. Vitamin A helps kidney and lung function and contributes to healthy skin and night vision, while vitamin K helps blood coagulation.
Cilantro also contains significant amounts of dietary fiber, zinc and thiamin. The herb has traces of vitamins C and E as well as several other nutrients, including riboflavin and niacin. Cilantro contains fewer calories than most other seasonings. It also has no fat or salt, unlike some other food flavorings. Cilantro may even protect the liver from toxins. A 2002 study showed that rats who consumed cilantro were less likely to suffer liver damage than rats who had not.
