Table 1. Consumption statistics: staple food

Note: (1) The consumption rate refers to the proportion of people who have consumed a certain kind of food in the past year. Consumption frequency refers to the times of foods that were consumed in the past year. Average consumption per time is the average weight of each type of food consumed per time. (2) In this survey, for the consumption frequency, we provided four units (times/day, times/week, times/month, times/year) for the participants to use according to their actual situation. All units are converted into times/year during the statistical analysis.
