  According to the Environmental Working Group, non-organic celery contains high levels of pesticides and is thus an excellent candidate for organic harvesting. Celery is very nutritious and a good source of fiber, Vitamins A and C, coumarins, and pthalides, which can potentially reduce blood pressure. Celery is also considered an excellent diet food, as it is low in calories.
