About this food
Corn sits in the Vegetables group. 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.
Nutrient insight
Potassium is the highest of the three at 12%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.
