To know the differences in food availability according to food insecurity level among the Mexican households.
We analyzed the database of the National Survey of Household's Incomes and Expenditures (n=27 445 households). Households were classified according to the Latin American and Caribbean Inventory of Food Security. The availability of each food group was estimated as grams per day per equivalent adult.
50.0% of Mexican households experienced some degree of food insecurity. Among households with food insecurity there was high availability of corn, wheat, egg, and sugars; but there was low availability of fresh fruits and vegetables, lean meat, poultry, seafood, milk, cheeses, and sweetened beverages.
Although in households with food insecurity there is lower availability of most food groups (both with high nutrient density and with high energy density); they have higher availability of cheap foods, which in some cases are only source of energy but do not provide nutrients.
了解墨西哥家庭中粮食供应情况根据粮食不安全程度的差异。
我们分析了家庭收入与支出全国调查数据库（n = 27445户家庭）。家庭根据拉丁美洲和加勒比粮食安全清单进行分类。每个食物组的供应量按每等效成年人每天的克数估算。
50.0%的墨西哥家庭经历了某种程度的粮食不安全。在粮食不安全的家庭中，玉米、小麦、鸡蛋和糖的供应量较高；但新鲜水果和蔬菜、瘦肉、家禽、海鲜、牛奶、奶酪和含糖饮料的供应量较低。
尽管在粮食不安全的家庭中，大多数食物组（包括高营养密度和高能量密度的食物组）的供应量较低；但他们有更多价格便宜的食物，在某些情况下，这些食物只是能量来源，不提供营养。
