About this food
About Onions: Vegetables are a key source of fiber and vitamins and are beneficial in CKD. Some are high in potassium, but slicing, boiling and discarding the water can remove about 30-50% of the potassium - a practical step. As a Vegetables item, its role in a kidney diet depends mainly on mineral content.
