"Breakdown of the average per capita intake of cereals by specific cereal-based commodity types,measured in kilocalories per person per day. This figure measures the primary equivalent of all food products derived from a given commodity (e.g. "wheat" represents the primary equivalent of its derived
products). Data refers to cereal food supply at the consumer level but does not account for consumer wastage."
