New Study on Protein, Healthy Aging, and Longevity ft. Layne Norton and Dr. Matthew Nagra
Simon Hill provides three key protein takeaways from a Harvard and Tufts University study on protein intake and healthy aging, addressing Layne Norton's interpretation and the plant vs. animal protein question.

Highlights
•
Plant protein is associated with healthier aging outcomes independent of total protein intake
Hill: the Harvard Nurses' Health Study found that higher plant protein intake was associated with significantly better odds of healthy aging (defined as no major chronic disease, good cognitive function, and no physical disability), while animal protein showed weaker or null associations.•
Protein quality debates miss the forest for the trees — total diet quality predicts health better than protein source
Hill: the protein source debate (plant vs. animal) is less important than total diet quality. Both plant and animal protein can support muscle synthesis and healthy aging when consumed in adequate amounts within a whole-food dietary pattern.Was this useful?
