In this episode, Prof. Stuart Phillips explains how protein can keep us healthy as we age. He also outlines when we should eat protein, how much protein we really need, and provides simple, practical advice to help you achieve it. Stuart is a professor in the Kinesiology Department at McMaster University. He’s the author of more than 400 scientific papers, many focusing on protein and muscle health, particularly during ageing.
With so much confusion around this topic - especially in the context of fitness and ageing - this episode will provide clear, evidence-based answers from one of the world’s leading scientists on the topic, to help you make smarter nutrition choices.
