Cost per 100 g* in Nigerian naira (NGN) and daily allowed intake in grams for food commodities available in Ebonyi.
The minimum (Min) and maximum (Max) daily intake are specified for an adolescent male and female in grams. For each food commodity it is specified if it is allowed within a diet type, which reflects the most restrictive diet in which the food can be included. The diet types are abbreviated as follows: OM for omnivore, PC for pescatarian, VE for vegetarian and VG for vegan. Note that the minimum intake for all specified food commodities is zero. For completeness we mention it explicitly in the table.
*Cost are obtained from the World Food Programme Nigeria country office.
