The concept of a single 'average African' diet is a misconception, as dietary patterns across Africa are incredibly diverse, influenced by a multitude of geographical, economic, and cultural factors. The data cited often represents a continental average that hides significant disparities. A look into regional calorie intake, macronutrient composition, and the socioeconomic forces at play reveals a far more complex picture than any single figure can portray.
Calorie Intake Varies by Region and Income
Calorie consumption in Africa is not uniform. A 2009 study estimated average daily per capita calorie intake for Sub-Saharan Africa (SSA) to be approximately 2,098 Kcal. However, this figure is a mosaic of different regional patterns:
- Central Africa: Often has the lowest intakes. One study indicated a daily per capita intake of around 1,820 kcal, influenced by high rates of food insecurity and conflict.
- Eastern Africa: A 2009 study estimated intake around 2,245 Kcal per day. This region also contains some countries with the lowest intakes, reflecting issues like drought and poverty.
- Western Africa: Estimates around 2,120 Kcal per day, with significant disparities within the region. Coastal areas often show higher consumption, contrasting with lower levels in drier, northern areas.
- Southern Africa: Historically has higher calorie availability compared to other parts of SSA, with estimates around 2,418 Kcal per day. Economic development, particularly in countries like South Africa, contributes to higher, though often less nutritious, consumption.
- Northern Africa: Generally more food secure, with calorie consumption levels often exceeding nutritional targets. However, this also comes with rising rates of diet-related diseases.
The Dominance of Carbohydrates and the "Nutrition Transition"
Across much of Africa, diets are heavily plant-based and carbohydrate-dependent, primarily relying on staple cereals like maize, millet, sorghum, and rice, or root vegetables such as cassava. A study evaluating food supply from 1990 to 2017 found that carbohydrates supplied around 73% of the total daily energy in Africa during this period. In contrast, the contribution from protein and fat was considerably lower.
However, a "nutrition transition" is occurring, especially in urban areas and middle-to-high-income countries. As people migrate to cities and incomes rise, diets shift towards more energy-dense, processed foods, along with increased consumption of meat, dairy, and added sugars. This has led to a "double burden of malnutrition," where undernutrition exists alongside rising rates of overweight and obesity. The Global Nutrition Report notes that Africa faces a burden of stunting in children alongside rising adult obesity, particularly among women. The World Bank's recent analysis highlights solutions and progress toward resilience in food systems.
Key Factors Influencing African Diets
Numerous factors interact to determine what and how much is eaten across the continent.
Food Insecurity and Affordability
Food insecurity is a persistent and worsening problem in many parts of Africa, driven by climate change, conflict, and economic disruption. In 2022, nearly 61% of Africans faced moderate or severe food insecurity, and 78% could not afford a healthy diet. Low-income households often resort to cheaper, energy-dense but nutrient-poor foods, while healthier options become less accessible.
Urbanization and Changing Lifestyles
Urban food environments offer increased access to processed foods and street food, which often have high levels of sugar, salt, and unhealthy fats. This shift is influenced by economic development, food prices, and marketing strategies. Traditional food preparation methods, which can be time-consuming, are also being replaced by faster, convenience-based options in cities.
Agricultural Productivity and Climate
Low agricultural productivity in many regions, coupled with vulnerability to extreme weather events, directly impacts food availability. Smallholder farmers, who produce much of the food, are particularly susceptible to climate shocks. This affects the diversity and nutritional quality of diets, especially in rural areas.
Gender and Socioeconomic Status
Studies show that food consumption patterns are influenced by socioeconomic factors and gender. For instance, adherence to a meat and egg-based diet is more common among younger, wealthier, and more educated individuals, while a fish-based diet is seen more among women with higher economic status. Women often bear a higher burden of food insecurity, and cultural norms can influence dietary choices.
Regional Dietary Snapshot
| Region | Average Calorie Intake (Approx.) | Primary Staple Foods | Key Nutritional Challenges |
|---|---|---|---|
| Eastern Africa | 2,245 kcal | Maize, millet, sorghum, potatoes | High undernourishment, stunting, food insecurity |
| Western Africa | 2,120 kcal | Cassava, yams, rice, maize, millet | Food insecurity, varying protein and fat intake |
| Central Africa | 1,820 kcal | Cassava, tubers, yams | Very low calorie intake, high severe food insecurity |
| Southern Africa | 2,418 kcal | Maize, wheat, meat (increasing) | Rising overweight/obesity alongside undernutrition |
| Northern Africa | >3,600 kcal (2017) | Wheat, barley, pulses | Emerging non-communicable diseases from diet shifts |
Summary of Macronutrient Composition
The macronutrient breakdown in African diets, while varying, generally reflects the high consumption of plant-based staples.
- Carbohydrates: Contribute the largest portion of daily energy, often around 73% for Africa as a whole. In many rural areas, this figure is higher due to reliance on staples.
- Fats: Fat consumption has been rising, especially in higher-income regions, driven by increased intake of processed foods and vegetable oils. However, in many areas, traditional fat sources like palm and groundnut oil remain common.
- Proteins: Protein intake is often low, particularly in low-income areas and rural populations heavily dependent on plant-based diets. Higher-income and urban areas show a greater consumption of animal-based protein sources.

Conclusion
There is no single answer to the question "how much does the average African eat?" The reality is a vast spectrum of dietary intakes shaped by a complex web of regional disparities, economic conditions, and environmental factors. While average calorie consumption on the continent is lower than in developed countries and is heavily carbohydrate-reliant, significant transitions are underway. Rising income and urbanization are shifting dietary patterns towards more processed and energy-dense foods, leading to the dual burden of undernutrition and overnutrition. Addressing these nutritional challenges requires nuanced, targeted strategies that acknowledge the immense diversity of the continent, promoting both food security and healthy diets.
