Gray Iron Newsletter reader, John C., says an annual physical examination revealed a steep rise in his PSA (Prostate Specific Antigen) test. As you know, an elevated PSA can lead to more expensive and invasive tests. Before having those, he decided to examine his dietary habits and realized his only recent change was adding a daily protein shake. (I do not know how many total grams of protein he was ingesting daily. He is not a regular exerciser.) He eliminated the protein shakes and says his PSA gradually returned to a normal range. I had never heard of anything like this before. Have you?
The debate among bodybuilders, lifters and other athletes about the amount of protein needed while training is ongoing. It won’t be settled today. PSA tests aside, certainly there is a protein upward limit that when exceeded it becomes unhealthy. If you have any experience or knowledge of elevated PSA as related to protein consumption, please comment below. As I said, I have never heard of this before. I didn't come with anything doing a Google search.
