Question: what sort of age does the protein seem to effect the older people

Alex Munro answered on 12 Jun 2011:

Protein is made up of amino acids; when we eat and digest protein, the amino acids get into our blood and this stimulates the creation of new muscle. This happens in humans of all ages – amino acids are the ‘anabolic stimulus’ for muscle protein synthesis… In older people, there are changes that take place in the muscle. One of these changes is that their muscle becomes less sensitive to the effects of amino acids, there is almost a ‘resistance’ to their effects. This may mean that more amino acids are required to stimulate the creation of new muscle in older people. This is why I’m looking into HOW we eat protein across the day, and whether changing the way we eat protein across the day might make a difference…
