Contribution of NOVA food groups to energy and nutrient supply in Mexican households

Abstract

Objective. To analyze the contribution of natural, processed and ultra-processed foods to energy and nutrient supply in Mexican households. Materials and methods. The da­tabase of the National Household Expenditure Survey 2013 was analyzed (n=58 001), which is a cross-sectional survey. Food supply (g/adult equivalent/day) and energy, macro- and micro-nutrient supplies were estimated. Foods were classified following the NOVA system. Households sociodemographic characteristics were analyzed as covariates. Results. Natural foods (NF) contributed with more energy (55.0%) followed by ultra-processed foods (UPF, 21.2%). NF were the main source of most nutrients. Processed culinary ingredients (PCI) and processed foods (PF) had high content of energy, total fats, and saturated fats, but low content of certain micronu­trients. Sodium was mainly available in PF (34.6%) and UPF (31.4%). Sugar-sweetened beverages, fast foods, and biscuits and cookies were the main UPF in terms of energy supply. Conclusions. In Mexican households, the PCI, PF and UPF had low nutritional quality.
