About this food
For Vegetables, Spinach 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
Potassium at 28% is the main consideration. Concentrated forms such as juice and dried fruit absorb faster; whole foods are gentler.
