People 66-years and older who consumed a high-protein diet, defined as consuming 20% or more of calories from protein, were 28% less likely to die over the next 18 years than people who consumed a low-protein diet, defined as consuming less than 10% of calories from protein, according to a study from researchers at the University of Southern California in Los Angeles, California, USA.

“[T]his was not affected by percent calories from fat, from carbohydrates, or from animal protein,” the paper notes.

In other words, a high-protein diet INCREASED the risk of dying prematurely in people 50-65 years-old, but REDUCED the risk of dying prematurely in those 66-years-old and older.
