About this food

Corn is a common member of Vegetables. 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. This helps when choosing similar foods.

Nutrient insight

Potassium is the highest of the three at 13%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.
