In this episode, I answer a listener’s question about whether I am worried about my phosphorus intake and whether a high phosphorus intake is ok as long as it is balanced by calcium. I describe the biochemistry and physiology of the system that regulates calcium and phosphorus, their distribution in foods, how to determine the right balance in the diet, and how to use parathyroid hormone (PTH) as a blood measurement to assess whether the dietary balance is working for an individual.
