Optimal nutrition is essential for reducing both all-cause and CVD mortality. Existing research highlights the importance of macronutrient type and quality in this context, with limited evidence in non-Western populations. We aimed to determine the association between macronutrient distribution and all-cause and CVD mortality in an African population as well as the contribution of the respective food sources. This cohort consisted of 1737 African men and women with a median observational time of 13 years, resulting in 19 456·6 person-years. CVD-related international classification for diseases, 10th revision (ICD-10) codes (I00–I99) were included when considering CVD mortality. Substitution analysis using partition and nutrient-density models assessed the relationship between macronutrient distribution and mortality. Higher intakes of complex carbohydrates (CHO), animal protein, total fat and MUFA were associated with decreased all-cause mortality risk. The partition model also revealed that substituting 200 calories (kcal) of plant protein with animal protein significantly reduced all-cause mortality risk by 39 % to 33 % (model 1–3). In addition, the isoenergetic substitution of 10 % total energy from total fat with total CHO led to a 17 % reduction in all-cause mortality risk (hazard ratio (HR) 0·83; 95 % CI 0·72, 0·96). No significant associations with CVD mortality were found. These findings partially agree with, yet also oppose, previous studies, emphasising the need for population-specific data. Research from high-income European populations may not directly apply to African contexts due to food insecurity, reliance on staple-based diets with low-quality plant proteins and lean, higher-quality animal protein sources, as well as differences in CVD disease aetiology.
