A 2024 study on metastatic breast cancer patients found that adopting a whole food, plant-based diet significantly lowered serum amino acid levels. This highlights that a range of factors, from diet to internal regulation, determine what would reduce the rate of amino acids in the body.

The human body maintains blood calcium within a tightly controlled, narrow range of approximately 8.5 to 10.2 mg/dL through an essential biological process known as negative feedback. This complex hormonal regulation is critical because proper calcium levels are vital for nerve function, muscle contraction, and blood clotting.

More than 99% of the body's total calcium is stored in bones and teeth, with the remaining fraction tightly regulated in the blood. The intricate process of how the body maintains this remaining blood calcium at a stable level is a classic example of a physiological negative feedback loop.
