The Democratic Republic of the Congo (DRC; République démocratique du Congo, RDC) contains extraordinary agricultural and culinary diversity, yet conflict, displacement and weak infrastructure repeatedly interrupt access to nutritious food and chronic-disease care. Its metabolic-health story is therefore not a simple shift from traditional to modern diets; it is the coexistence of food insecurity, disrupted markets and a growing burden of diabetes and hypertension.
Key takeaways
- DRC and the neighboring Republic of the Congo are different countries and require separate health and food-system analysis.
- Cassava, plantain, maize, beans, groundnuts, fish, leafy vegetables and regional forest foods contribute to diverse Congolese cuisines.
- Conflict and displacement can interrupt farming, trade, medication and diabetes monitoring.
- Undernutrition can coexist with obesity, hypertension and elevated blood glucose.
- Congolese diaspora communities face further dietary change in Belgium, France, Canada, the United Kingdom and elsewhere.
The DRC extends from the Congo Basin to highland, savanna and Great Lakes environments. There is no single “Congolese diet.” Cassava may appear as roots, leaves or fermented preparations; plantain, maize, rice, beans, groundnuts, fish, insects, vegetables and fruit vary by ecology, season, ethnicity and household resources.
Traditional foods can support metabolic health when meals provide fiber, protein and dietary variety. Their effects still depend on processing, portions and context. Cassava products are often low in protein unless paired with beans, fish, groundnuts or other protein sources. Food safety and proper preparation are essential.
In eastern and central-eastern DRC, insecurity and displacement disrupt roads, markets and health services. People living with diabetes may lose access to medication, glucose monitoring and regular meals precisely when stress and infection increase health risks.
In 2026, WHO reported that DRC ranked third in its region for the number of adults aged 20–79 living with diabetes, with an estimated 2.9 million cases in 2024. WHO's work in Maniema reached patients whose routine care had been disrupted by isolation and persistent insecurity. WHO: continuity of diabetes care in eastern DRC
This does not mean diabetes has replaced infectious disease or acute malnutrition. These burdens overlap. Humanitarian planning should therefore protect insulin and essential medicines, blood-pressure care and appropriate food for chronic disease alongside emergency nutrition.
A household can experience inadequate food quantity or diversity while relying on cheap refined starches, salty packaged foods or sweetened drinks whenever cash and markets permit. Children may face undernutrition while adults develop hypertension or abnormal glucose metabolism.
Obesity should not be treated as evidence that a household has secure access to nutritious food. Metabolic risk often reflects the quality, regularity and affordability of available food rather than personal failure.
The DRC has enormous agricultural potential, but roads, storage, energy, insecurity and access to finance influence whether farmers can reach markets and consumers can afford diverse local foods.
Priorities include support for cassava safety and processing, legumes, vegetables, fruit, fisheries and small livestock; reduced post-harvest loss; safer market infrastructure; and regional trade that rewards producers. Local value chains can improve both livelihoods and metabolic health when minimally processed foods compete successfully with imported ultra-processed products.
Congolese migration has produced important communities in Belgium, France, Canada, the United Kingdom and the United States. Migration may improve reliable food access while changing work patterns, physical activity, ingredient availability and exposure to processed foods.
Diaspora health information should retain familiar dishes and names rather than replacing them with generic “Western” menus. Practical adaptations include maintaining beans, leafy vegetables and fish; moderating refined starch portions; reducing added sugar in drinks; and protecting shared meals without portraying Congolese hospitality as a health problem.
