- Factors influencing food waste during lunch of fourth-grade school childrenPublication . Martins, Margarida Liz; Rodrigues, Sara S.P.; Cunha, Luís M.; Rocha, AdaThis study aims to explore the factors that influence plate waste at lunches served in primary schools. Data was collected for all fourth-grade children attending 21 primary schools from the city of Porto (Portugal) (n = 463). Plate waste was evaluated by the weighing method and factors influencing plate waste were collected by observation of menu and canteen characteristics and through the application of a questionnaire to children aiming to evaluate factors related to preferences and dietary patterns. Logistic regression was performed to identify predictors of plate waste. It was observed that fish menus and composed dishes showed a higher tendency for increased plate waste. However, this effect was not observed when adjusted for other variables. Soups without pulses and blended soups were less likely to be discarded by children. The presence of the teacher during meals and the possibility for children to leave the canteen whenever they wish, protected both the main dish and the soup from being wasted. A higher number of children in the canteen was associated with increased soup waste. As expected, children more pleased with the sensory characteristics of the main dish and soup were less likely to waste food. Children who consumed high-saturated fat content mid-morning snacks were more likely to waste soup. The main factors associated with plate waste were related to the presence of teachers during the mealtime, school meal policies and the meals’ sensory characteristics. Additionally, soup waste was determined by its composition, mid-morning snacks and the number of children in the canteen.
- Evaluation of food waste at a Portuguese geriatric institutionPublication . Martins, Margarida Liz; Henriques, Ana Sofia; Rocha, AdaCare institutions attending to older adults are responsible for their food supply, which influences their health and quality of life. Food waste at care institutions has been reported to be a matter of great concern, that requires regular monitoring. In this study, we aim to quantify food waste in the food service of an elderly institution, both as leftovers and plate waste. Data collection was performed over 15 consecutive days, at lunch and dinner served to older adults. The aggregate weighing of food was performed before and after distribution, as well as after consumption. Leftovers and plate waste were calculated by the differences in weight. During the study period, 2987 meals were evaluated, corresponding to 1830 kg of food produced, of which only 67% was consumed. For each meal, approximately 610 g of food was produced per older adult, and only about 410 g were consumed, corresponding to 150 g of leftovers and 50 g of plate waste. Food waste rep-resented 36.1% of meals served, composed of 24.1% leftovers and 12.0% plate waste. The wasted meals would be enough to feed 1486 older adults and would correspond to annual losses of approximately €107112. Leftovers and plate waste were above the limits of acceptability (below 6% and 10%, respectively), indicating excessive food waste. High values of leftovers are related to the food service system and staff, pointing to the need for improvements during the planning and processing of meals. On the other hand, high plate waste values are associated with consumers, indicating the low adequacy of the menu regarding to older adults’ habits and preferences.
- Food consumption determinants and barriers for healthy eating at the workplace: a university settingPublication . Lima, João P. M.; Costa, Sofia A.; Brandão, Teresa R. S.; Rocha, AdaBackground: A wide variety of social, cultural and economic factors may influence dietary patterns. This work aims to identify the main determinants of food consumption and barriers for healthy eating at the workplace, in a university setting. Methods: A cross-sectional observational study was conducted with 533 participants. Data were obtained through the application of a self-administered questionnaire that included socio-demographic information, food consumption determinants and the main perceived barriers for healthy eating at the workplace. Results: The respondents identified “price” (22.5%), “meal quality” (20.7%), and “location/distance” (16.5%). For women, the determinant “availability of healthy food options” was more important than for men (p < 0.001). The food consumption determinants at the workplace most referred to by respondents were related to the nutritional value. Smell, taste, appearance and texture, and good value for money, were also considered important for choosing food at the workplace. Respondents referred to work commitments and lack of time as the main barriers for healthy eating at the workplace. Conclusions: Identification of determinants involved in food consumption, and the barriers for healthy eating, may contribute to a better definition of health promotion initiatives at the workplace aiming to improve nutritional intake.

- O açúcar que comes quando bebes: impacto de uma estratégia de consciencializaçãoPublication . Lima, João; Augusto, Catarina; Gaspar, Joana; Brandão, Teresa R. S.; Rocha, AdaA obesidade é um dos problemas de saúde mais graves, a nível mundial. A procura de soluções para a designada epidemia do século XXI contínua, sendo que a relação entre o consumo de bebidas açucaradas e o peso corporal tornou-se uma questão pertinente. Avaliar o impacto de uma estratégia de consciencialização sobre o teor de açúcares simples presentes num conjunto de bebidas disponibilizadas na cafetaria de um estabelecimento de ensino. Foram analisadas as vendas de um conjunto de bebidas antes e após a intervenção. A intervenção baseou-se na afixação de um expositor com as bebidas e a representação da quantidade de açúcares simples, em açúcar, sob o mote O açúcar que comes quando bebes". Procedeu-se a uma análise das proporções das vendas, com um intervalo de confiança a 95%. Após a análise estatística dos rácios foi observada uma redução estatisticamente significativa no número de unidades vendidas, após a intervenção, de refrigerantes do tipo cola e das bebidas gaseificadas. Além disso, houve um aumento no número de unidades vendidas, com significância estatística, de néctares de frutas, chá/infusões e leite de chocolate. A intervenção na cafetaria da Escola de Hotelaria e Turismo de Coimbra foi bem sucedida tendo-se verificado uma redução efetiva das vendas de bebidas açucaradas.
