Approximately 85% of the body's phosphorus is stored in bones and teeth, with the remainder playing crucial roles in cellular metabolism. When phosphorus levels in the blood become too high, either from diet or impaired kidney function, it must be bound to prevent adverse health effects.

A Chinese study found the average lanthanum concentration in major foods was approximately 28.9 $\mu$g/kg, illustrating that trace amounts of this rare earth element are naturally present in our food supply. While not an essential nutrient for humans, understanding what foods contain lanthanum is part of a growing interest in trace elements.
