Myth: High Protein Diets are Bad for the Bones and Kidneys
It seems that carbohydrates and fats take much of the blame for various health issues, but protein has also been accused of causing certain health problems, mostly related to kidneys and bones. It seems these concerns have surfaced more lately due to the popularity of certain high protein diets.
Early research linked protein intake to increased urinary calcium which was thought to lead to excess bone loss. However, newer and better research done since does not support that concern. The evidence now shows that protein does not have a negative effect on bone, and in most cases it even has a protective effect.
It was also thought that high protein intake over-stressed the kidneys and could lead to kidney damage. Once again, though, later research has shown that high protein intake itself does not damage normally healthy kidneys.
Bone health and kidney health are supported by numerous nutrients and lifestyle factors. Getting a healthy overall diet with plenty of potassium and nutrients related to bone health is far more influential on your bone and kidney health than a higher than average protein intake.
To be clear, we are referring to the effects of protein on normally healthy bones and kidneys. If a person has a pre-existing condition or kidney dysfunction, they should consult their health professional to determine what diet is best in their circumstance.
