A large study published in the peer-reviewed medical journal ‘Cell Metabolism’ earlier this year made headlines throughout the world with this claim. It shows that a high protein intake – unless the protein comes from plants – is associated with a significant higher risk to die of cancer (fourfold) and in general dying at an earlier age (73% during the course of the study).

"Almost everyone is going to have a cancer cell or pre-cancer cell in them at some point. The question is: Does it progress?” Turns out one of the major factors in determining if it does is protein intake". Valter Longo, Director, USC Longevity Institute in Los Angeles (and lead researcher behind the study above).
