The result of an epidemiological study conducted in South Korea points to the same direction: Persons with the highest protein intake had a 1.3 higher risk of faster GFR loss. A study published in the journal Advances in Nutrition looked at 26 different studies to see the impact of higher protein intakes on kidney health. The annual change in eGFRcysC was doubled in patients with a total daily protein intake in excess of 1.20 g/kg ideal body weight, compared with an intake less than 0.80 g/kg. Subgroup analyses also indicated that the association between protein intake and decline in eGFR was threefold stronger in patients with diabetes compared to those without diabetes.

In short, the study found no detrimental effects of a high protein diet on kidney health and no negative changes to any health markers. Diets aren’t one-size-fits-all.
