00:00protein is in the cereal, the coffee, even the water. But a review of more than 350 studies
00:06suggests many Americans are overdoing it. The paper was published on July 31st in the
00:12Cell Press journal Cell Press Blue. Corresponding author Dudley Lamming of the University of
00:18Wisconsin-Madison says protein clearly helps muscle growth in active people. His point is
00:24that most people are relatively sedentary and are likely consuming more than they actually need.
00:30The review found protein restriction can improve metabolism, limit cellular damage,
00:35and help cells keep working normally. One reason may be a hormone called FGF-21.
00:40It rises when protein intake falls, and it can raise energy expenditure,
00:45improve blood sugar control, and reduce inflammation. Mice with elevated FGF-21 lived
00:51longer than typical mice. Meanwhile, new U.S. guidance this year nearly doubled recommended
00:56protein. Lamming argues the real answer is personalizing protein by age and activity,
01:03not one number for everyone. Disclosure, this video contains stock footage and content created
