The Longevity Nutrition Expert: You’re Focusing On The WRONG Protein Met...

In this conversation, Simon Hill discusses protein amount versus source with Walter Willett. Across the usual intake range studied (around 12 to 25 percent of energy), total protein or protein density shows little association with major health outcomes, while the source is strongly linked: higher animal protein, particularly from red meat (and some dairy), associates with higher cardiometabolic risk, whereas plant protein from legumes, soy and nuts associates with lower risk.
