About this food

Egg is a common member of Dairy & Eggs. 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. This helps when choosing similar foods.

Nutrient insight

Egg's phosphorus (22%) is worth noting - especially with Animal source (higher absorption) as the source, since absorption differs a lot.
