Summary
Small Island Developing States (SIDS) have complex food sources beyond imports. Understanding diverse food systems (Aid, Buy, Grow, Share, State, Wild) is crucial for tackling non-communicable diseases (NCDs) and malnutrition.
Area of Science:
- Food systems research
- Public health nutrition
- Island studies
Background:
- Small Island Developing States (SIDS) exhibit high rates of non-communicable diseases (NCDs).
- Reliance on imported food is a key structural driver of NCDs in SIDS.
- Limited understanding of diverse food sources in SIDS exacerbates this issue.
Purpose of the Study:
- To systematically map and classify food sources in Small Island Developing States (SIDS).
- To analyze the societal, cultural, and environmental aspects of food sourcing in SIDS.
- To understand the interconnections between various food sources.
Main Methods:
- Conducted a systematic search of 14 peer-reviewed databases and 17 grey literature repositories.
- Identified and analyzed 56 articles and 96 documents related to food sources in SIDS.
- Developed a novel classification system: Aid, Buy, Grow, Share, State, and Wild food sources.
Main Results:
- Identified significant heterogeneity in food sources beyond imported items.
- Developed an interactive, open-access evidence map illustrating interconnections between food sources.
- Demonstrated complex and often unexpected pathways from food sourcing to consumption.
Conclusions:
- A comprehensive understanding of diverse food sourcing is essential for Small Island Developing States (SIDS) to achieve their 2030 malnutrition goals.
- Addressing NCDs in SIDS requires acknowledging the complexity of their food landscapes.
- Policy interventions must consider the variety, extent, nature, and changes in food sources.

55.7K
In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

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...

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

1.1K
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...
