With the European population growing older, the challenge is to keep an increasing number of seniors across all European countries healthy and active. In Europe, between 13.5 % and 29.7 % of older adults living at home are malnourished or at risk of protein energy malnutrition. PROMISS aims to better understand and ultimately prevent protein energy malnutrition in seniors. Thereby, PROMISS will contribute to improve active and healthy ageing.

European older adults have been studied according to their appetite and protein intake profiles, and the relevant dietary and physical activity behavioural determinants were identified. A survey with 1,825 older adults aged 65 years or above in five European countries (Netherlands, United Kingdom, Finland, Spain and Poland) was conducted in June 2017.
Older adults with a poor appetite and lower level of protein intake is characterized by a larger share of people aged 70 years or above, living in the UK or Finland, having an education below tertiary level, who reported some or severe financial difficulties, having less knowledge about dietary protein and being fussier about food. This group also tends to have a higher risk of malnutrition in general, oral-health related problems, experience more difficulties in mobility and meal preparation, lower confidence in their ability to engage in physical activities in difficult situations, and a lower readiness to follow dietary advice. Therefore, effective dietary strategies to increase protein intake should take into account sensory properties, familiarity, affordability, accessibility and convenience.
Consumption of certain foods at a certain moment of the day and physical activity level or pattern were associated with a lower risk of having lower protein intake. Low level of physical activity emerged as a risk factor for having a lower protein intake in older adults with poor appetite, and vigorous physical activities between lunch and dinner were associated with a lower risk in older adults with good appetite.
This study provides an overview and highlights the similarities and differences in older adults’ profiles, as well as the challenges in promoting healthy ageing regarding protein intake. Recommendations for optimal dietary and physical activity strategies to prevent protein malnutrition were derived, discussed and tailored according to older adults’ profiles.

Sarcopenia is a progressive loss of muscle mass and muscle strength that may lead to disability, falls, and hospitalisation. The very old, those aged 85 years and older, are the fastest growing age group in most western societies and are at especially high risk of sarcopenia. Onset of sarcopenia may be partly explained by diet. Therefore, we aimed to explore the role of dietary patterns and protein intake in the risk of sarcopenia over 3 years. Our study, the Newcastle 85+, was based in North East England, and involved more than 750 people aged 85 years old. These participants had their diet estimated by a 24 hour multiple pass recall (people are asked what foods and drinks they consumed in the past 24 hours) on two different days of the week and from this, dietary patterns were derived. Sarcopenia was measured over 3 years according to a muscle mass index, gait speed and grip strength. We identified three dietary patterns: ‘Low Red Meat’, ‘Traditional British’ and ‘Low Butter’ that varied by unsaturated fat spreads/oils, butter, red meat, gravy and potato consumption. We found that very old adults who had a dietary pattern high in foods characteristic of a traditional British diet (high butter, red meat, gravy and potato consumption, and high fat and energy intake), especially compared to a low butter dietary pattern (high in unsaturated fat spreads/oils, fibre, percentage of energy from protein and starch) had an increased risk of sarcopenia even when overall protein intake was good. These results add to the limited literature on the role of the whole diet in sarcopenia in very old adults.
