8. Celery
Though kind of bland and stringy, there is a surprising amount of nutrition in celery. However, it is really high up on the Dirty Dozen list, being coated with up to 68 hormone disrupting pesticides.
Celery is also relatively tasteless, so we tend to dip it in unhealthy stuff in order to make it palatable. Still, as long as you buy organic and watch the toppings, celery can help you feel full without adding many calories to your daily diet.
