Dr. Steven Gundry’s new book, “The Plant Paradox,” has some compelling information about the value of limiting your animal protein intake to 2 to 3 ounces a few times a week to increase longevity. I believe this is solid advice and this is my typical strategy. I am convinced most of us eat far too much protein and it’s wise to replace most animal protein with safe fish like sardines and anchovies, and even then limit total protein to 30 to 60 grams depending on your lean body mass.
Gundry reviews how cattle, pigs and sheep all carry a sugar called Neu5Gc, which your immune system recognizes as foreign when you eat their meat. There is significant data suggesting that when your immune system is exposed to the foreign sugar molecule Neu5Gc from red meat, you develop an antibody to the lining of your own blood vessels, A radically reduced intake of animal protein could explain some of the longevity advantages.
