Is the "eat less protein" for longevity advice actually backed by adequate science? Find out in this deep-dive Q&A with amino acid researcher Dr. Joel Brind.

Learn why lumping all protein together is misleading, why individual amino acids act as signaling molecules (not just building blocks), and how glycine may help counteract inflammation, support longevity, and fill in the gaps that low-protein headlines leave out.
You'll also learn where glycine deficiency shows up in the typical modern diet, and simple ways to close the gap through food and supplementation.
We also discuss why comparing plant protein to animal protein is more complicated than it seems, and why viral "less protein = longer life" studies may be oversimplifying decades of amino acid research.
Subscribe for more science-backed nutrition breakdowns, and let me know in the comments if you want more deep dives into amino acids and longevity.
