a Household income per capita in minimum wages.
b Model 1: adequacy of fruits and vegetables. Model 2: adequacy of fruits and vegetables, macronutrients and fats, calcium, sodium and potassium. Amount of ultra-processed foods less than or equal to the amount observed for both models.
d Average (standard error).
e Cost in Reais (percentage in relation to the cost observed in the period) calculated as: [(optimized cost - observed cost)/observed cost × 100].
