World Diabetes Day 2026 and One Health

The food people can afford, the places they can be active and the healthcare they can reach shape the opportunities to reduce type 2 diabetes risk and obtain a timely diagnosis. World Diabetes Day 2026, on November 14, focuses on early diagnosis and risk reduction under the 2026–27 theme “Early action on diabetes.”[1] A One Health approach helps connect that message with the systems and environments around us.

One Health recognizes the interdependence of human, animal, plant and ecosystem health and brings relevant sectors together to address shared challenges. [2] For diabetes, the useful connections include how food is produced and made accessible, how communities are designed, and whether health services respond to the conditions of daily life. This approach asks how prevention can support human health while taking environmental sustainability into account.

The prevention discussion here concerns type 2 diabetes: healthy eating and regular physical activity can help prevent or delay it. [3] Type 1 diabetes is not prevented through diet or exercise and requires insulin treatment. [4] People with either type need accessible diagnosis and continuing care.

Food systems connect nutrition and environmental health

Advice to eat well is harder to follow when nutritious food is unaffordable or difficult to find. Income, prices, food production and local food environments influence what reaches the plate. [5] A One Health response considers these conditions alongside the environmental costs of producing and consuming food. Those costs include pressures on land, water and biodiversity. [6] WHO and FAO recommend considering nutrition, environmental impact, affordability and local cultural needs together, recognizing that choices involve trade-offs. [6]

Schools, workplaces and public institutions could use food purchasing policies to make nutritious meals affordable while setting environmental criteria for suppliers. For example, a meal service could improve the range of nutritious foods offered, review prices and measure food waste. Local authorities could also support retailers and markets that improve access to healthy food. [5] These are practical policy options to assess locally, rather than promises that a particular purchasing policy will prevent diabetes.

Community design can support daily movement

Physical activity depends partly on whether everyday journeys and public spaces are safe and accessible. Walking, cycling and wheelchair mobility can provide opportunities to be active; WHO notes that safe environments for these activities are not available to everyone. [7] Transport and planning decisions therefore belong in the prevention discussion, alongside advice given in a clinic.

Planners, environmental teams and residents could work together on connected walking routes, safe crossings and accessible green spaces. Parks and greenery can support activity and reduce exposure to excessive heat. [8] Providing shaded places to rest can be considered when designing routes for local conditions. These measures connect health, mobility and the urban environment. Their value should be assessed through access and use, without assuming that any single intervention will produce a specific reduction in diabetes.

Early diagnosis needs affordable and reachable care

Economic pressures also connect prevention with treatment. Food insecurity can make diabetes harder to manage, and some people face a choice between paying for food and paying for healthcare. [9] Services should ask about these pressures without blaming patients for circumstances they cannot readily change.

A practical response could link clinical care with community support. A clinic that identifies difficulty affording food could offer a referral to a local assistance service. Staff could also ask whether transport, appointment times or taking time off work make testing and follow-up difficult, then work with community organizations and service planners on feasible solutions. Screening activities should include clear arrangements for results, clinical assessment and continuing care, rather than ending with a test.

Type 2 diabetes can develop with few noticeable symptoms. Even when feeling well, people who may be at increased risk should discuss appropriate testing with a healthcare professional. Increased thirst, frequent urination, fatigue, blurred vision or unexplained weight loss warrant prompt medical assessment. Testing needs to reflect individual circumstances; a risk checklist cannot establish a diagnosis. Once diagnosed, treatment and checks for complications remain essential. [3]

Working across sectors with communities

For World Diabetes Day, public health teams could bring food providers, environmental and transport planners, health services and residents together to identify a shared local priority. Residents should help define the barriers and judge whether proposed changes are useful. Teams could track practical results, such as affordable meal availability, use of accessible routes or completion of follow-up after testing. Connecting these efforts gives One Health a concrete role in diabetes prevention and care, while keeping clinical outcomes and environmental benefits subject to evaluation.
