When it comes to finding options for your kidneys, you can’t go wrong with fresh fruits and vegetables. One of the best options for maintaining and protecting your kidneys is to consume ample amounts of celery regularly, which is also a low-calorie way to control your hunger as well. In addition to eating fresh celery, you can consider consuming celery juice or add celery chunks to your daily cleanse or smoothie as well. Celery is a natural laxative and this is a natural way to flush out harmful toxins from your blood and organs. Consider trying to eat more celery throughout the week and consider enjoying fresh celery juice in the morning instead of orange juice.
