Will too much protein damage your kidneys? Does protein shorten longevity due to its effec

Well SupportedIn a model, the relative risk of mortality associated with protein intake crossed over around age 65, suggesting higher protein diets became beneficial above this age.

Well SupportedHigh protein intake (over 2 grams per pound) has not shown adverse effects on urea, nitrogen, or kidney function in individuals without pre-existing kidney conditions.

Not SupportedThe claim that high protein diets reduce longevity is not compelling in humans, with some evidence suggesting the contrary.

Partially SupportedProtein intake of 1.0, 1.2, 1.4, and 1.6 g/kg/day is associated with 12%, 21%, 27%, and 33% lower mortality risk, respectively, compared to the RDA of 0.8 g/kg/day.
