High Protein Diets and Kidney Disease

[drtbear1967]

A common concern in the fitness field is that high protein intakes can impair kidney function. Unfortunately, this theory has been based off of studies or clinical work involving individuals with pre-existing kidney disease. If you do NOT have kidney disease, it is highly unlikely that a high protein diet will do any harm to your kidney function. As always, stay on track of your routine physicals and blood work to ensure that you are in optimal health and meet with your physician if you have any further concerns.

I get this from my doc all the time. Urine test shows protein in it, and I get the lecture. They tell me that having the high protein will harm the kidneys just as you state at the beginning of your post. I never felt any difference between being on a lot of protein and when I didn't have a lot.

Doc's only know the medical model and have very little understanding of nutrition

Dr Jason Fung ( a kidney specialist) is known for his fasting information. He is definitely in the know since he deals with kidneys all day; in a recent interview he was asked this exact question. Unless you have specific kidney issue, high protein does absolutely nothing to your kidney based on all current studies and real world practice.
