¹Values are means for the number of snacks per day (snack frequency), the energy value of each snack (snack energy), and the energy contribution of snacks (energy from snacks) expressed in kilocalories and as a percentage of total energy intake for the total population (per capita) and for those consuming at least 1 snack on a given day (per consumer). Data are from the Mexican National Health and Nutrition Survey, 2012 and Mexican National Nutrition Survey, 1999.
