Today it was a real privilege to talk to the world-leading expert, Professor Don Layman about protein. Professor Layman is considered the "Godfather" of protein.  I have followed his research over the years and this has been base for my own understanding of the importance of protein and how it works in our bodies.

I believe that protein is the most misunderstood part of our diets and if we optimised our protein intake, we would have much better health. I have summarised a lot of Professor Layman's research in my videos on protein. If you are interested in learning and understanding more, then check these out on YouTube.

Professor Layman and I talk about how much protein we should eat and why older people need more. We delve into the myths that protein causes cancer, kidney disease and osteoporosis. We discuss the best sources and options for vegetarians. We also talk about athletes and kids health. I hope you will enjoy listening as this wonderful and humble man shares his knowledge with us.

- Protein needs
- Muscle maintenance
- Role of amino acids
- Importance of leucine to trigger muscle growth
