Senior citizens' vitamin D supplements intake: evidence from Denmark.

BACKGROUND: Several public interventions have been designed in recent years to urge the intake of vitamin D supplements among the senior population to avoid the direct and indirect consequences associated with vitamin D deficiency. However, the effectiveness of these public campaigns remains quite limited. In an online survey, the current study investigates attitudes towards vitamin D supplements intake and associated behaviours in a representative sample of Danish senior citizens (N = 554) - that is, individuals aged 55 years and above. RESULTS: Approximately half of the sample reported taking vitamin D supplements in the preceding year. Furthermore, being male and having a positive perception of individuals' own health status increased the probability of being a non-user. Increasing confidence in the information provided by health authorities (such as medical doctors and pharmacies) is particularly critical for enhancing the likelihood of non-users to purchase vitamin D supplements. However, also encouraging the uptake of vitamin D supplements in specialized supermarkets with stands and promotions seems an appealing and practical solution to increase seniors' uptake of vitamin D supplements. CONCLUSIONS: The present study outlines the characteristics of senior Danish non-users of vitamin D supplements. Additionally, the research provides information on the strategies that could be applied by public organizations to foster vitamin D supplements intake among this target segment of the population. © 2023 The Authors.

How attitude towards food fortification can lead to purchase intention.

This research examines how consumers' general attitude towards food fortification can lead to their intention to purchase vitamin D fortified food. Specifically, it is argued that this effect can be mediated by the perceived personal benefit of consuming vitamin D fortified food; and that the indirect effect is moderated by problem awareness and the perceived appropriateness of vitamin D fortification in a given food product category. Perceived personal benefit and problem awareness reflect the individual versus public interest to improve health, respectively. The model is tested among a sample of 1263 adult consumers who evaluated ten mainly animal-based food products, including dairy and processed meat products. Results of moderated mediation analysis indicate that general attitude towards food fortification are associated with perceived personal benefit, especially under conditions of high problem awareness. Purchase intention of vitamin D fortified food does not only depend on consumers' assessment of their personal benefit of enriching foods with vitamin D, but also the perceived appropriateness of a given product to be fortified. Importantly, high appropriateness can offset the attenuated effect associated with low problem awareness.

Determinants of meal satisfaction in a workplace environment.

Workplace lunches are recurrent meal occasions that can contribute to the general well-being of employees. The objective of our research was to study which factors influence consumers' satisfaction with these meals by exploring the relative role of food-related, personal, situational factors. Using a longitudinal approach, we monitored a total of 71 participants compiled and experienced 519 meals from their workplace canteen buffet during a three-month period; in addition the composed lunches were photographed. Before and after the lunch choice period respondents filled in a questionnaire on several meal-related variables. A mixed modelling approach was used to analyse the data. Meal satisfaction was directly associated with a positive ambience and a positive evaluation of both the quality of the food eaten and the buffet assortment, whereas the meal's energy content did not contribute to meal satisfaction. Additionally, meal satisfaction was associated with a more positive mood, lower hunger level as well as feeling less busy and stressed after lunch. The buffet assortment, a more positive mood before lunch and mindful eating contributed to the perceived food quality, but not associated with the hunger level before lunch. Time available, mindful eating and eating with close colleagues were positively associated with perceived ambience. The results indicate that consumers' satisfaction with workplace meals can be increased by putting emphasis on the quality of food served, but equally important is the ambience in the lunch situation. Most of the ambience factors were related to available time and mental resources of the participants and the possibility to share the meal with close colleagues. These are factors that can be facilitated by the service provider, but not directly influenced.

EURRECA-A framework for considering evidence in public health nutrition policy development.

A key step toward developing appropriate evidence-based public health nutrition policies is determining exactly how that evidence should be collected and assessed. Despite this the extent to which different evidence bases influence policy selection is rarely explored. This article presents an epistemological framework which offers a range of considerations affecting this process generally and with particular implications for both micronutrient requirements and the role of behavior in the policy-making process. Qualitative case study data covering 6 European countries/regions (Czech Republic, Italy, the Netherlands, Nordic countries, Poland, and Spain), and three micronutrients (folate, iodine, and vitamin D), have been presented to illustrate the relevance of the Framework.

A psyllium fiber-enriched meal strongly attenuates postprandial gastrointestinal peptide release in healthy young adults.

Dietary fiber (DF) and protein are essential constituents of a healthy diet and are well known for their high satiety impact. However, little is known about their influence on postprandial gastrointestinal (GI) peptide release. Our aim in this single-blind, randomized, cross-over study was to investigate the effects of DF and/or protein enrichments on satiety-related metabolic and hormonal responses. Sixteen healthy, nonobese volunteers participated in the study and ingested 1 of 5 isoenergetic test meals in a randomized order on separate days. The test meals were as follows: 1) low in protein (2.8 g) and fiber (7.6 g); 2) low in protein (2.6 g) and high in soluble fiber (psyllium, 23.0 g); 3) high in protein (soy, 19.7 g) and low in fiber (6.2 g); 4) high in protein (18.4 g) and fiber (23.0 g); and 5) white wheat bread. Serum insulin and plasma glucose, ghrelin, glucagon-like peptide 1 (GLP-1), and peptide YY (PYY) concentrations were determined for 2 h following the meals. In addition, hunger and satiety ratings were collected. Postprandial glucose, insulin, ghrelin, GLP-1, and PYY responses all differed among the meals (P

Consumer appeal of nutrition and health claims in three existing product concepts.

This paper reports on consumers' reactions towards calcium-enriched fruit juice, omega-3 enriched spread and fibre-enriched cereals, each with a nutrition claim, health claim and reduction of disease risk claim. Cross-sectional data were collected in April 2006 from a sample of 341 consumers in Belgium. Consumers' reactions to the carrier product, functional ingredient and claim combinations were assessed as perceived convincingness of the claim, credibility of the product, attractiveness of the product, and intention to buy the product, while accounting for differences in product familiarity, attitudinal and demographic characteristics. Generally, health claims outperformed nutrition claims, and both of these claim types outperformed reduction of disease risk claims. Comparing consumer reactions across product concepts revealed clear preferences for fibre-enriched cereals as compared to the other two concepts. The interaction effects between claim type and product concept indicated that reduction of disease risk claims are perceived very well in omega-3 enriched spreads, particularly in terms of perceived convincingness of the claim, while not appealing to consumers in the other product concepts. Positive attitudes towards functional foods and familiarity with the concrete functional product category boosted the claim type and product ratings, whereas perceived control over own health and perceiving functional foods as a marketing scam decreased all product concept's appeal.
