Background: The interest in meat alternatives has increased over the years as people embrace more varied food choices because of different reasons. This study aims to analyse the nutritional composition of ready-to-use meat alternatives and compare them with meat (products). Methods: Nutritional composition values were collected in 2022 of all ready-to-use meat alternatives in Belgian supermarkets, as well as their animal-based counterparts. A one-sample t-test was performed to test the nutritional composition of ready-to-use meat alternatives against norm values, while an independent samples t-test was used to make the comparison with meat. Results: Minced meat and pieces/strips/cubes scored favourably on all norm values. Cheeseburgers/schnitzels, nut/seed burgers and sausages contained more than 10 g/100 g total fat. The saturated fat and salt content was lower than the norm value in each category. Legume burgers/falafel contained less than 10 g/100 g protein. Vegetarian/vegan minced meat and bacon contained fewer calories, total and saturated fat, and more fibre compared to their animal-based counterparts. Conclusions: Minced meat and pieces/strips/cubes came out as the most favourable categories regarding nutritional composition norm values. Vegetarian/vegan steak came out the least favourable compared to steak, while vegetarian/vegan minced meat and vegetarian/vegan bacon came out the most favourable compared to their animal-based counterparts.

Background: On Wednesday 18/03/2020 Belgium was placed in lockdown in order to curb the spread of COVID-19. Lockdown can lead to loneliness, boredom, anger, anxiety and depression, which in turn have an influence on food choices and physical activity (PA). This study aims to map the adjustments in food choices and PA by Flemish adults during lockdown. Methods: Chi square tests were performed to investigate the relationship between adjustments in food choices, PA and demographic variables. Results: A total of 1.129 respondents filled in the online questionnaire, aged between 18 and 81 years. The healthiest food choices were made by respondents living alone during lockdown, whilst people cohabiting with others increased their PA significantly. Moreover, the dietary adjustments of adults living with children evolved more favourably to healthier choices then those cohousing with other adults. However, respondents living with other adults showed a more favourable pattern regarding adjustments in PA. The strongest increase in sedentary behaviour was observed in students. Conclusions: This study shows the impact of lockdown on both PA and food choices, where healthier adjustments were observed in PA and respondents were prone to consume unhealthier food.

Background/Objective: Transitioning towards plant-based dietary patterns is essential to improve health and reduce environmental impact. Hospitals represent a key setting to implement such dietary shifts, yet data on the availability of plant-based meals in healthcare institutions remain scarce. Methods: A cross-sectional survey was conducted across Dutch-speaking hospitals in Belgium to assess the meal plans and whether vegetarian or fully plant-based meal options were available for patients. Besides availability, the frequency and perceived barriers were assessed. Furthermore, the meal plans were analyzed to get an overview of the vegetarian and plant-based food options that were offered in different types of Belgian hospitals. Results: The availability of plant-based meal options was limited across hospitals. No meaningful differences were observed between general hospitals and other hospital types, including psychiatric, rehabilitation, and specialized hospitals. While plant-based fats and oils were widely available, key protein-rich plant foods such as legumes and minimally processed meat alternatives were rarely offered in all types of hospitals. Knowledge gaps among food service staff were observed, and structural barriers—including the need to accommodate diverse dietary requirements—were reported. Conclusions: Belgian hospitals currently underutilize the potential of vegetarian and plant-based nutrition to support patient health and sustainability goals. Strengthening institutional food environments by increasing the availability of nutritionally adequate plant-based meals represents a feasible and impactful strategy to align hospital practice with dietary guidelines and preventive healthcare priorities.
