Eswatini’s food and metabolic-health story combines maize-based meals, beans, pumpkins, leafy vegetables, groundnuts and livestock traditions with rapid dietary change and a substantial burden of diabetes and obesity. A useful response must protect nutritious local foods while improving access, primary care and the wider commercial food environment.
Eswatini’s landscapes range from highveld to lowveld, shaping agriculture and food access. Maize is a central staple, commonly prepared as porridge and served with vegetables, beans, groundnuts, fermented milk, eggs or meat. Sorghum, pumpkins, sweet potatoes and indigenous leafy vegetables can add diversity, while sugarcane is economically important in irrigated lowland agriculture.
Maize provides energy but meals become nutritionally stronger when legumes, vegetables and protein sources are included. Whole or less-refined grains generally retain more fibre than highly refined meal. The same principle applies across traditions: preparation, portion size and the combination of foods matter more than assigning a moral label to maize or any other staple.
Protecting indigenous vegetables and legumes can support micronutrient intake and agricultural diversity. It should occur alongside food-safety measures and without implying that traditional foods alone can reverse established diabetes.
WHO estimates that 30.1% of adults in Eswatini had obesity in 2022, with an uncertainty interval of 25.9% to 34.6%. WHO also lists diabetes among the country’s leading causes of death in 2021. These are population-level estimates and modeled cause-of-death data, not personal predictions.
HIV, tuberculosis and nutritional vulnerability remain major concerns, meaning that communicable and noncommunicable diseases coexist. Integrated primary care can reduce fragmentation by combining blood-pressure and glucose screening with established infectious-disease services and reliable access to medicines.
Priorities include supporting beans, vegetables and drought-tolerant crops; improving local storage and markets; strengthening school meals; making water readily available; and protecting children from intensive marketing of sugary beverages and ultra-processed snacks. Food policy should also recognize the difference between sugarcane as an agricultural commodity and frequent consumption of products high in free or added sugars.
