Summary
This umbrella review highlights the need for integrated research on food systems. Future studies should adopt a holistic approach to sustainability, considering all dimensions for transformative change.
Area of Science:
- Food systems research
- Sustainability science
- Public health
Background:
- Food system interventions are crucial for improving sustainability, addressing complex links between consumption, production, and environmental impact.
- Emerging research explores food system initiatives and their dual benefits for human health and sustainability outcomes.
Purpose of the Study:
- To conduct an umbrella review of systematic and scoping reviews on food system initiatives.
- To explore the relationship between these initiatives and human health and sustainability outcomes.
Main Methods:
- An umbrella review methodology was employed, searching five databases from 2015-2024.
- Included systematic and scoping reviews focused on food system initiatives with co-benefits for health and at least one sustainability outcome.
Main Results:
- 20 reviews were included, focusing on sustainable diets, food security, urban agriculture, food supply chains, education, and the global syndemic.
- Few reviews (15%) addressed all three sustainability outcomes (social, economic, environmental). Economic sustainability was often reported alongside other dimensions.
- No clear trends linked intervention topics to specific outcomes, indicating a need for holistic research.
Conclusions:
- Robust, multidisciplinary systems research is essential for integrating all sustainability dimensions.
- Transformative food system change requires a comprehensive approach that considers social, economic, and environmental factors holistically.

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
432
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

02:11The Roles of Bacteria and Fungi in Plant Nutrition
46.5K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
