In an aging population, support for independent living is increasingly critical for older generations. Currently, sarcopenia is a major cause of frailty, which increases the risk of decreased mobility, falls, morbidity, and mortality and leads to dependence on third parties. Sarcopenia is preventable by consumption of adequate protein. However, many older people do not meet the recommended daily allowance of protein, thereby supporting dependence rather than independent living. Current literature indicates that a protein drink could be an appropriate product for older peoples' protein consumption. We were interested in autonomous persons whose nutritional decisions were still self-determined and thus could preventively influence their personal health. This study evaluated three commercially available protein drinks in three focus groups (n = 25) to gain insight into which aspects influence the perception of commercial protein drinks on community-dwelling older people (age, 76.8 ± 4.9). Findings from the focus groups revealed only aspects, which influenced the perception of commercial protein drinks negatively. Most importantly, the drinks did not comply with relevant aspects when buying (healthy) foods, which where naturalness, freshness, locally grown ingredients, and trust. Furthermore, the target group did not see a need for additional protein consumption. Thus, we identify important aspects to be considered for the development of a target-group-specific protein drink as well as more suitable communication to prevent distrust in order to support independent living for community-dwelling older people.

Investigating unconscious human behaviours is a complex issue, given that people have hardly access to their unconscious. Food-related behaviour is one of these behaviours in which the unconscious plays a central role. Therefore, the connection of the unconscious and food-related behaviour is difficult to comprehend. Hence, our exploratory study deals with the relationship between implicit motives as an important part of the unconscious and their relationship with food-related behaviour. For this purpose, we used the Operant Multi-Motive Test (OMT), which offers information about implicit motives of individuals. Based on 37 qualitative problem-centred interviews conducted in Bavaria, Germany, we identified seven eating action types that we combined with the results derived from the OMT. These deliver profound insights into how people eat due to their identity. The approach of this study is explorative and provides a first insight into a possible relationship between implicit motives and food-related behaviour that are presented descriptively. Our initial results show that a relationship between implicit motives and food-related behaviour can be assumed, although it cannot be directly deduced from the sole analysis of food-related behaviour. However, nutrition consultancies, food companies, policy makers and advisors may be interested in these insights related to understanding the impact of the unconscious on food-related behaviour.

Food-related behavior is a very complex topic, as it affects the most diverse areas of life. Accordingly, wide varieties of disciplines have already dealt with the topic to understand it better. The result is that there is neither a uniform nutrition knowledge nor a uniform nutrition behavior. In order to reduce the complexity of a field of study, there is the methodical means of type-building. Both commercial and academic studies have already formed nutrition types, either by means of standardized questionnaires or with a specific content focus. However, since both individual and social aspects influence food-related behavior, we investigate how people integrate eating into their everyday life against the background of (competing) individual and social demands by focusing on the individual point of view, for which a mixed methods approach is used. Based on 42 semi-structured, problem-centered interviews conducted in Germany in 2017, we built qualitative food-related types in a first step, which are analyzed in this article using a quantitative content analysis and cross-over analysis to identify the particular distinguishing feature(s) of each type and test them for significance. The results show the prominent characteristics for each type and indicate furthermore that subjectivization, self-determination, the body as an instrument of power, adaptation to the environment and being overstrained with the own behavior are particularly prominent when it comes to eating. Moreover, we clearly identified The Overstrained and The Relaxed as independent eating action types, which we could not find anywhere else. The study shows that interventions, especially for The Overstrained and The Controlled, are necessary to achieve a relaxed approach to eating in everyday life. At the same time, systematic approaches should be used to intervene in cases of overstraining or controlled behavior.
