Research output: Contribution to specialist publicationArticle


The world’s ageing populations are increasing every year. In 2016, 18% of the UK’s population was aged 65 years or older – by 2046, this group will account for nearly a quarter of the people living in the British Isles.

Add to this the fact that normal ageing is associated with a gradual decline in muscle mass, known as sarcopenia which can impair muscle function and strength, it is crucial, now and in the future, to prolong people’s health span and their ability to be active and live independently. For that we need to understand the role of dietary intake of protein to promote healthy and active ageing.
