Other similar indicators can be developed focused on a minimum intake of different nutrients (e.g. proteins) rather than energy (see NutVal.net, an initiative from the World Food Programme WFP and the UN Refugee Agency UNHCR). The cost of the dietary energy needs — the food poverty line — is estimated based on the assumption of the energy requirement for a healthy life of a representative individual in a given population (usually 2 100 calories per capita per day) and the cost of a food basket required to meet that energy requirement, taking into account the need for a properly balanced diet and the food habits of a given population. The share of the population whose expenditures (or income) fall under the food poverty line is considered food poor. This indicator captures the access dimension of food insecurity.
