title: [Food insecurity and variety of food in Mexican households with children under five years].
abstract: OBJECTIVE
  To describe the variety of feeding in households with children under five years by level of food insecurity.
  
  
  METHODS
  We analyzed data from the database of the National Household Income and Expenditure Survey 2008, using the Mexican Scale for Food Security and constructed variables for "per capita expenditure", "purchase frequency" and "quantity purchased" for 12 food groups, associating them with food insecurity (FI).
  
  
  RESULTS
  The prevalence of households classified with food insecurity was 48%. We found a relationship between lower food variety and greater food insecurity, with a possible "substitution effect" of protein sources among households with FI.
  
  
  CONCLUSIONS
  As food insecurity severity increased, the variety of the diet decreased.
