WHAT IS A FOOD SYSTEM?
A food system includes everything that happens to get food from where it's grown or produced to our tables and beyond. It’s a complex, interconnected web.
At its core, a food system has three main components: the food supply chain, people and institutions, and the drivers and outcomes.
The Food Supply Chain
The food supply chain follows food from production to our plates, then back again through waste management. This cycle involves:
- Production: Growing crops, raising animals, and harvesting seafood.
- Processing: Turning raw ingredients into products ready for sale.
- Distribution: Transporting and delivering food to stores, markets, and food programs.
- Access: Making sure people can get and afford nutritious food nearby, in ways that feel good and fair.
- Consumption: Preparing and eating food at home or elsewhere.
- Waste Management: Reducing, composting, or recycling food waste and leftovers.
Every part is connected. Changes in one area can affect the entire chain.
People and Institutions
A wide range of people and organizations work together to keep the food system running smoothly:
- Farmers and fishers: grow and harvest food.
- Processors: turn raw products into packaged or prepared foods.
- Distributors and transporters: move food from farms to stores and markets.
- Retailers and food service providers: sell and serve food to consumers.
- Consumers: purchase and eat food.
- Waste managers: handle food waste responsibly.
- Policymakers and planners: create rules and programs (such as food handler certification training) that affect food systems.
- Advertisers, marketers, and educators: influence food choices and awareness.
Everyone has an important role in shaping the food system and helping it adapt to changing needs.
The Drivers and Outcomes
The food system is shaped by several forces—called drivers—that influence how food is produced, accessed, and consumed. These drivers include:
- Food security: whether people have reliable access to nutritious food.
- Public health: nutrition and health outcomes are influenced by food quality and accessibility.
- Climate change: affects growing conditions and food availability. Learn more about the impacts of Climate Change in our area.
- Built environment: healthy community design is important as it influences how people access and obtain food.
- Government policies: guide land use, food safety, pricing, and sustainability.
- Economic factors: influence affordability and the viability of food businesses.
- Global trade: impacts food availability and price.
The food system also produces outcomes that affect society and the environment, including:
- Environmental impact: effects on pollution, resource use, and climate change.
Drivers and outcomes are linked. Sometimes an outcome can become a driver—like pollution causing climate change, which then affects food production. These loops shape how the food system works.
Sustainable Food Systems: Healthier People, Stronger Communities
A sustainable food system supports health, equity, and the environment—core values of public health. It ensures that:
- Nutritious food is affordable and accessible for all, supporting better physical and mental health.
- Food production respects ecosystems by reducing emissions, protecting soil and water, and supporting biodiversity. Learn more about sustainable food choices on the health unit’s Food And the Environment page.
- Food workers are treated fairly and paid livable wages, building stronger, more just communities.
Culinary traditions are celebrated, preserving cultural heritage and fostering a sense of identity and belonging. - Local food producers are supported, strengthening ties to land, food, and one another.
- Communities become more resilient through strong local food networks and reduced reliance on long supply chains. Learn more about community food security.
