About this food
How to think about Vegetables: Spinach is worth a closer look - 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 (17%). For patients on potassium restriction, portion size and leaching are the two levers that matter for foods like Spinach.
