Malnutrition (or undernutrition) affects at least three million people in the UK (1.3 million are over the age of 65), with 93% of these living in the community (British Association for Parenteral and Enteral Nutrition [BAPEN], 2018). Malnutrition has an estimated cost of £19.6 billion in England, with older adults (≥65 years) accounting for over 50% of this cost (Stratton et al, 2018). Malnutrition has adverse effects if unidentified and untreated.
