3. Description of the project: In order to estimate the nutrients consumption from the food consumption module of the EHCVM (Section 7B), each of the food items reported in that module is matched with a food item in the Food Composition Table (FCT) or Food Database (FDB) of choice, and nutrients composition are then compiled in what is called the nutrients composition table (NCT). 


4. Description of the dataset: it includes the nutrient composition of each food item reported by the household survey of Comoros.

METHODOLOGY
--------------------------
1. Methodology: To build the Nutrients Composition table of Comoros we followed three steps, which are described below:

Step 1. Revise and identify all food items reported in Section 7B of EHCVM
As some of the food items were reported in local language or were not easily found in the main FCTs used for the matching, additional resources were needed.
1.1	Consultation with key informants
We contacted key informants in Comoros to obtain food items translation terms to French or English, and the scientific names (when available) of edible plants local species. 
Key informants consulted:
	Hamidou Said Ounais, statician at the INSEED: Institute Nationale de la Statistie et des Etudes Economiques -Comores
	Mme Nadjahou Abdoulatuf , Biodiversity Service (CNDRS: Centre National de Documentation et de Recherche Scientifiques)
Based on the food list found in the database, 148 food items were considered.

1.2	Consultation of specialized literature 
In order to identify the best suitable item in the FCTS used for the matching we consulted bibliographic resources specialized in Comoros fauna and flora, as well as gastronomy and culinary practices.

Step 2. Select the food composition tables/databases (FCT/FDB) to be used for the matching
Only internationally validated FCT/FDBs were considered for the matching, and we prioritized the FCT/FDB to be searched based on geographical location as well as language and cultural linkages. The FCT/FDBs used by number of food items and percentage from the total are describe below:

	Composition Table for Western Africa 2018  (103 items, 72% of the total).
	Kenya Food Composition Tables 2018  (20 items, 14% of the total)
There were some food items that were not found in those two FCTS and alternative composition tables were searched.
	USDA Food Database  (10 food items, 7% of the total)
	ASEAN food Composition Database 2014  (5 food items, 3% of the total)
	Brazilian Food Composition Table 2018  (1 food item, 0.7% of the total)


Step 3. Identify the most appropriate food matching method for each food item
In order to apply the food matching correctly we identified  the most appropriate matching method based on:

3.1	The definition of the food item and the identification of a suitable food item in any of the FCTs consulted. 
If the food item is well defined and concrete in the survey it is possible to find a corresponding match in the FCT of choice and make a direct matching. However, if the food items refer to a group of foods (ex: autres patisseries) it is necessary to do the matching with several food items in the FCT and do the average of the nutrients content.
 
3.2	The cooking method used for the food item before consumption
The cooking method applied to a food item before being consumed has an impact in the micronutrient content (see Moltedo A, et al 2020), and thus it is important to apply the corresponding  conversion factors such a Yield or Retention factors to obtain more accurate information on the micronutrients consumption.

Individual food consumption surveys usually collect the cooking method of the foods being consumed. However, in household consumption surveys the cooking method is usually omitted, thus it is important to consult resources on culinary practices and local gastronomy, as reported in Step 1.

When there was no information on the main cooking method used for a particular food item we calculated the average of the food item cooked by different methods.

3.3 The information available for mixed dishes
The 2018/2019 EHCVM included three mixed dishes (ancharis or rougails) as individual food items that couldn’t be found in any of the consulted FCT/FDBs.
For those food items we used the local recipe and calculated the nutrients content by ingredient.
