Eating mistakes that could quietly steal your later years by Erin Elizabeth for Health Nut News
Dr.Jason Fung, a nephrologist and author of two previous books, “The Obesity Code” and “The Complete Guide to Fasting,” has now released a third, “The Longevity Solution,” which is the topic of this interview. This book was also co-written with James DiNicolantonio, Pharm. D, who also happens to be the co-author of my latest book, “Superfuel.”
The motivation for “The Longevity Solution” came from a discussion with DiNicolantonio. “He’d already talked about salt in his book, ‘The Salt Fix.’ In ‘Superfuel,’ he talked about good fats, bad fats, and super fuel. We thought it would be great to tie everything together in terms of the real dietary determinants of longevity,” Fung says, adding:
“I spend a good section of the book talking about protein — the different types of protein, animal versus plant protein, for example, and how much protein [you need]. These are really important questions because there’s so much [information] out there, and you don’t know who to believe.”
From my review of the book, I think that is probably one of the most valuable pieces because there’s so much confusion about protein. There’s good reason for this confusion because it’s a complex topic. An important part of the equation is the mammalian target of rapamycin (mTOR), also known as the mechanistic target of rapamycin, a very important pathway responsible for controlling autophagy.
If you inhibit mTOR — which you can do by restricting protein — you activate autophagy, which is a good thing. However, I’ve personally made the mistake of not eating enough. While excess protein can activate mTOR, your protein needs do increase with age, as you need to counteract progressive loss of muscle mass. So, your age really needs to be taken into account as well.
