In 2021, the Government of Nigeria, with IITA and technical support from Intake, conducted a National Food Consumption and Micronutrient Survey (NFCMS). Funding for the survey was provided by the Gates Foundation, the Foreign, Commonwealth & Development Office (UK), Nutrition International, UNICEF, USAID, and the World Bank.
This web-page provides a set of interactive data visualizations to summarize a selection of results for the dietary component of the survey. The web-page has been prepared for participants invited to attend the Dietary Data Use Workshop in Abuja, Nigeria 12-14 August, 2024.
Data visualizations are presented in six parts: Part I. Macronutrient Contribution to Energy Intake; Part II. Nutrient Intake Inadequacy; Part III. Diet Quality Metrics for Women; Part IV. Diets of Infants and Young Children; Part V. Consumption of Biofortified Foods; and Part VI. Main Food Sources of Energy and Nutrients.
We invite you to explore the data visualizations below to learn about the results from the dietary component of the national survey.

Data for the NFCMS was collected in 2021 using a probability sample, population-based cross-sectional survey, with stratification by six regions: 1. North Central 2. North East 3. North West 4. South East 5. South South 6. South West
Sampling within each region followed a two-stage random selection strategy. In the first stage, EAs were selected by adopting principles of Probability Proportional to Size (PPS) using systematic sampling. Sixty-five (65) EAs within each region were selected. In the second stage, eligible respondents were randomly selected within the sampled EAs.
The demographic groups of focus for the survey were: women of reproductive age (WRA) aged 15-49 years, pregnant women aged 15-49 years, and children aged 6-59 months and micronutrient status of non-pregnant adolescent girls aged 10-14 years.
For the dietary component of the survey, data was collected using a diet questionnaire (topics included infant feeding, biofortification, and fortification) immediately followed by a quantitative 24-hour dietary recall collected using the INDDEX24 Dietary Assessment Platform. A sub-sample of respondents completed a repeat interview two to three days later, these respondents completed a short diet questionnaire followed by a quantitative 24-hour dietary recall collected using INDDEX24.
Note: All data visualizations below reflect analyses adjusted for survey sampling weights adjusted for non-response.
-
The visualizations in Part I provide show the mean percent of macronutrient contribution to energy intake by demographic group at the national level, and by residence (urban vs. rural area).
-
Part II of the the dietary data visualizations focus on results for nutrient intake inadequacy. Results are presented for the following nutrients: protein, calcium, iron, zinc, vitamin A, thiamine, riboflavin, folate, vitamin B12, and vitamin C. The visualizations in Part II provide these results for each demographic group at the national level and by residence (urban vs. rural area). In addition, data for non-pregnant women are presented by zone and wealth quintile, and data for children are presented by sex
-
Part III of these dietary data visualizations present results for three diet quality metrics for women: 1. The Minimum Dietary Diversity for Women (MDD-W), a metric to assess dietary diversity; 2. The Global Diet Quality Score (GDQS), a metric of overall diet quality as it relates to nutrient adequacy and reduced risk of diet-related non-communicable diseases (NCDs); and 3. The Global Diet Recommendations (GDR) Score, a metric developed to proxy WHO dietary recommendations to protect against diet-related NCDs.
-
Part IV presents data for infants and young children (6-23 months). Figures 13 and 14 present the mean nutrient density of the complementary diet for children 12-23 months in urban and rural areas, and for boys and girls separately. Figure 15 presents data for the World Health Organization (WHO) infant and young child feeding (IYCF) indicators.
-
Part V of these data visualizations provides consumption results for specific biofortified foods. Results are presented for non-pregnant women by region and by wealth quintile for three different biofortified foods: yellow cassava, orange-fleshed sweet potatoes, and orange maize. These data were collected with a separate diet questionnaire, not as part of the 24-hour dietary recall collected with the INDDEX24 Dietary Assessment Platform.
-
Part VI of these data visualizations provides results for three demographic groups - non-pregnant women, children 6-23 months, and children 24-59 months - to show the main food sources for energy and a set of key nutrients: protein, calcium, iron, zinc, vitamin A, thiamine, riboflavin, folate, vitamin B12, and vitamin C.
