Hypothesis
What food-based indices assessing nutritive value and environmental impact exist for classification or ranking of meals or diets?
Conclusion
The study aims to identify and review existing food-based indices that assess both the nutritive value and environmental impact of meals and diets.
Supporting Evidence
- Current food production and consumption practices are impacting both human and planetary health.
- Food-based labelling is a common public-health strategy aimed at influencing consumption practices.
- Previous work has identified existing models for labelling of individual food products based on their environmental impacts and nutritive value.
Takeaway
This study is looking at how we can better understand the nutritional and environmental impacts of the meals we eat, so we can make healthier and more sustainable choices.
Methodology
The study follows the PRISMA-P guidelines for systematic reviews and will involve a structured search of multiple bibliographic databases to identify relevant studies.
Potential Biases
There is a risk of bias due to the potential for language translation issues and the subjective nature of some included studies.
Limitations
The varied methodologies used to create indices and the diverse range of information included in these indices may complicate direct comparisons.
Participant Demographics
No specific group of participants or populations will be included or excluded.
