Background: Plant-based meat alternatives (PBMA) are considered an alternative to animal products. We aimed to understand the patterns and drivers of consumption of PBMA and their nutritional contributions using dietary modelling, whilst also considering the relevance of processing.
Methods: This study used a mixed methods exploratory sequential approach. Semistructured online interviews (n = 19) with consumers and nonconsumers of PBMA were conducted. Thematic analysis of interviews considered drivers of PBMA consumption, with content used to develop personas to represent key concepts driving incorporation (or lack of intake) into dietary patterns. Diets were modelled for personas, based on recommended and typical population intake and with variations in processed foods based on the Nova food classification system, including PBMA. Diets were analysed against nutrient reference values.
Results: The main drivers of PBMA consumption were animal welfare, health improvement and environmental concerns. Convenience, cost, taste, processing and thoughts that the nutritional value of PBMA was lesser than meats were all described. Six personas were identified from the interview content. The three most disparate personas (age, dietary pattern and nutrient requirements) were used for dietary modelling. Nutrient analyses showed diets predominantly meeting reference values, with deficiencies more likely when modelled on food choices typical of population intake and diets excluding processed foods.
Conclusions: This study found that PBMA may have beneficial nutritional qualities such as lower saturated fat and higher dietary fibre when compared to their meat equivalents. PBMA may have a place in a healthy diet, whilst alleviating animal welfare and environmental concerns which were identified as key drivers of consumption.

Background: Gallbladder and biliary tract cancer (GBTC) increasingly aggravates the global malignancy burden. This study aimed to evaluate the updated condition of GBTC temporal burden trends and inequalities from 1990 to 2021.
Methods: Data on GBTC were extracted from the Global Burden of Disease (GBD) 2021 study.

Food serves not only as a source of individual physical sustenance but also a central element in shaping social relationships and culture within families and communities. The concept of foodscapes has emerged as a valuable framework for understanding the intricate connections between food, the environment, and society, highlighting both the physical and cultural dimensions of food. Production and consumption practices of traditional healthy foods, such as the Zambian traditional fermented milk mabisi, evolve over generations, a process influenced by the foodscape they are embedded in.

Regular physical activity is essential for the healthy development of children, and sports clubs are one of the main drivers of regular exercise. Previous studies have demonstrated that public subsidies can increase participation rates in sports clubs. The effectiveness of funding in increasing participation rates depends on multiple factors, such as geographic location, the size of the sports club, and the socio-economic conditions of the population.

Ecosystems globally have reached critical tipping points because of climate change, urbanization, unsustainable resource consumption, and pollution. In response, international agreements have set targets for conserving 30% of global ecosystems and restoring 30% of degraded lands and waters by 2030 (30×30). In 2021, the United States set a target to jointly conserve and restore 30% of US lands and waters by 2030, with a specific goal to restore coastal ecosystems, namely wetlands, seagrasses, coral and oyster reefs, and mangrove and kelp forests, to increase resilience to climate change.

Trait-based approaches have been increasingly used to relate plants to soil microbial communities. Using the recently described root economics space as an approach to explain the structure of soil-borne fungal communities, our study in a grassland diversity experiment reveals distinct root trait strategies at the plant community level. In addition to significant effects of plant species richness, we show that the collaboration and conservation gradient are strong drivers of the composition of the different guilds of soil fungi.
