Measuring diet at a societal level is an inexact science
Measuring diet at a societal level is an inexact science – as researchers generally have to rely on people keeping track of what they eat over a period of several days – and people may be inclined to under report their consumption patterns. Evidence suggests that people may throw away about 10-20% of the food they buy and underreport how much they eat by around 20–40%.
