ABSTRACT

Type 2 diabetes (T2D) is emerging as a significant health concern among African pastoralist communities, historically known for low rates of non-communicable diseases due to their physically active lifestyles and traditional diets. However, recent shifts toward sedentary living and the adoption of calorie-dense, processed foods have disrupted these metabolic advantages, increasing vulnerability to diabetes and related disorders. This review investigates the evolving relationship between dietary patterns and diabetes risk in pastoralist populations across sub-Saharan Africa. It explores the nutritional composition of traditional diets, the health impacts of nutrition transitions, and the broader sociocultural, environmental, and genetic factors influencing these shifts. Evidence from emerging epidemiological studies highlights rising rates of obesity, glucose intolerance, and insulin resistance in semi-urbanized and sedentary pastoralists. The review emphasizes the need for culturally tailored public health strategies, community-based metabolic monitoring, and integration of traditional and modern healthcare systems. It also identifies key research gaps, including the need for longitudinal studies, nutrigenomics, and microbiome research to better inform diabetes prevention in these transitioning populations.

Keywords: Pastoralist communities, type 2 diabetes, dietary patterns, nutrition transition, African health.
