• In surveys with multiple days of dietary intake data for the same subject, the nutrition statistics are computed using the average of food consumption across the reported days.
• The calculations consider all individuals in the population: consumers, i.e. those individuals who consumed the foods of interest during the survey period, and non-consumers, i.e. those who did not.
• In the default view, summary statistics are calculated for the whole survey population. Filters can also be applied to obtain specific estimates for different population groups, for example adults and children. In this case, nutrition statistics are calculated automatically by the platform based on the filters applied by the user.
• Subjects with missing sex and/or age information are excluded from the calculations.
• Missing values in food composition data linked to the foods consumed are either imputed from available food composition tables or left as missing. For each dataset, information on how missing values were treated are available in the survey metadata (i.e. survey details).
• If the missing values in the food composition data have a significant impact on the statistics for nutrient intake, the statistics are not displayed.

This infographic displays the average contribution of different foods and food groups to the overall intake of selected micronutrients (vitamins and minerals).

For each micronutrient, the centre of the pie chart displays the average daily intake for the surveyed population. The average micronutrient intake from the food groups is displayed by hovering over different sections of the pie chart. The average micronutrient intake from the food subgroups and food items are displayed by clicking on the sections of the pie chart.

The average micronutrient intake from different foods and food groups is calculated by summing up the micronutrient intakes from foods and food groups reported by every subject in the selected survey sample and dividing the result by the number of subjects in the sample.

This infographic displays the average contribution of different foods and food groups to the overall intake of selected macronutrients (i.e. protein, carbohydrate, fibre, fat, and saturated fat).

For each macronutrient, the centre of the pie chart displays the average daily intake for the surveyed population. The average macronutrient intake from the food groups is displayed by hovering over different sections of the pie chart. The average macronutrient intake from the food subgroups and food items are displayed by clicking on the sections of the pie chart.

The average macronutrient intake from different foods and food groups is calculated by summing up the macronutrient intakes from foods and food groups reported by every subject in the selected survey sample and dividing the result by the number of subjects in the sample.

This infographic displays the contribution of three main energy-providing macronutrients to overall daily energy intake. The inner part of the pie chart displays the average percentage contribution of carbohydrate, fat and protein to the average daily energy intake of the survey population. For comparison, the outer part of the pie chart displays the WHO and FAO recommended proportions of macronutrients in the diet¹. The shaded parts of this outer circle represent the range of recommended intakes.

The average percentage contribution of macronutrients to the average daily energy intake is calculated based on the average intake of carbohydrate, fat and protein for the survey sample. The total carbohydrate, fat and protein intake for each subject are summed up and divided by the number of subjects in the sample. The average total daily intake of carbohydrate, fat and protein are then multiplied by 4, 9 and 4 respectively (the Atwater factors) to estimate the energy intake from these macronutrients². The obtained estimates are then divided by the total energy intake to express the percentage contributions of each of the three macronutrients to the average daily energy intake.
