About this food

For Vegetables, Corn is a typical example. 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

The most striking number here is potassium (7%). For patients on potassium restriction, portion size and leaching are the two levers that matter for foods like Corn.
