About this food
About Corn: 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.
Nutrient insight
Corn's potassium is the top contributor (11% of its limit), so its potassium density deserves attention. In CKD stage 3-4 the kidneys clear potassium less well - control portions, and peeling, slicing or boiling can help.
