People 50- to 65-years old who consumed a high-protein diet, defined as consuming 20% or more of calories from protein, were 1.73 times more 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.

“None of these associations was significantly affected by controlling for percent calories from total fat or for percent calories from total carbohydrates,” the paper notes.

“However, when the percent calories from animal protein was controlled for, the association between total protein and all-cause or cancer mortality was eliminated or significantly reduced, respectively, suggesting animal proteins are responsible for a significant portion of these relationships.”
