About this food

Whey belongs to the Dairy & Eggs category. 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.

Nutrient insight

Whey's phosphorus is the top contributor (135% of its limit). Source matters: animal phosphorus absorbs at 60-80%, additive phosphorus near 100% - the same number can mean very different real loads.
