It's also a great diuretic.
We eat a lot of celery. Most of my bases for dishes like my vegetable stock that I use in soups and many others contains celery, onion, carrot. I put chopped celery in a lot of things and eat it raw as well. Nice with some nut butter for a snack or just teamed up with some chopped carrot sticks with hummus.

Caroline, raw cabbage salad is excellent if you can tolerate cabbage.
