Zambia’s food and metabolic-health story centers on maize-based nshima, diverse relishes, beans, cowpeas, groundnuts, leafy vegetables, fish, insects and livestock foods. National dietary guidelines now provide a strong framework for connecting traditional meals, agricultural diversity and prevention of noncommunicable disease.
Maize dominates national production and many household meals, but Zambia’s food systems also include cassava, sorghum, millet, sweet potatoes, beans, cowpeas, groundnuts, vegetables, fruit and extensive freshwater fisheries. Regional patterns differ, and urban food environments increasingly include refined snacks and sugary beverages.
Nshima provides staple energy, while the relish determines much of a meal’s protein, fibre and micronutrient content. Beans, cowpeas, groundnuts, leafy vegetables, kapenta or other fish, edible insects, eggs and meat can all contribute. Whole or less-refined grain forms generally retain more fibre than highly refined maize meal.
The goal is not to remove a culturally central staple. It is to protect portion balance and ensure that nutritious relishes are affordable and available throughout the year.
Zambia published its first food-based dietary guidelines in 2021. The guidelines recommend varied staples, daily vegetables and fruit, daily pulses or nuts, fish, insects or other animal-source foods, safe food handling, physical activity, and limits on ultra-processed foods and foods high in salt, sugar and fat. This provides an unusually clear foundation for schools, clinics and public procurement.
WHO estimated age-standardized hypertension prevalence among Zambian adults aged 30–79 at 32.3% in 2019, with an uncertainty interval of 26.3% to 38.8%. WHO estimated that noncommunicable diseases accounted for 31.2% of deaths in 2021. These modeled estimates describe populations and include uncertainty.
Malaria, HIV, tuberculosis, maternal-child undernutrition and food insecurity remain major concerns. Prevention and treatment should therefore be integrated rather than placing chronic disease in competition with infectious-disease priorities.
Useful measures include diversifying beyond maize, expanding pulses and horticulture, protecting fisheries, reducing post-harvest losses, and aligning school meals with the national dietary guidelines. Safe water, reduced sugary-drink exposure and accessible blood-pressure and glucose screening can reinforce food-system action.
