About this food

About Whey: Dairy products are high in phosphorus with high absorption and should be limited. With eggs, the white is a low-phosphorus protein while the yolk is much higher - treat them differently. As a Dairy & Eggs item, its role in a kidney diet depends mainly on mineral content.

Nutrient insight

Whey's potassium is the top contributor (8% of its limit), so its potassium density deserves attention. In CKD stage 3-4 the kidneys clear potassium less well - control portions, and peeling, slicing or boiling can help.
