Global trade agreements have shaped the food system in ways that alter the availability, accessibility, affordability, and desirability of ready-to-eat foods. We assessed the time trends of ultra-processed foods purchases in Mexican households from 1984 to 2016. Cross-sectional data from 15 rounds of the National Income and Expenditure Survey (1984, 1989, 1992, 1994, 1996, 1998, 2000, 2002, 2004, 2006, 2008, 2010, 2012, 2014 and 2016) were analyzed. Food and beverage purchases collected in a daily record instrument (over seven days) were classified according to their degree of processing according to the NOVA food framework: (1) Unprocessed or minimally processed foods; (2) processed culinary ingredients; (3) processed foods; and (4) ultra-processed foods. From 1984 to 2016, the total daily energy purchased decreased from 2428.8 to 1875.4 kcal/Adult Equivalent/day, there was a decrease of unprocessed or minimally processed foods (from 69.8% to 61.4% kcal) and processed culinary ingredients (from 14.0% to 9.0% kcal), and an increase of processed foods (from 5.7% to 6.5% kcal) and ultra-processed foods (from 10.5% to 23.1% kcal). Given that ultra-processed foods purchases have doubled in the last three decades and unprocessed or minimally processed foods purchased have gradually declined, future strategies should promote the consumption of unprocessed or minimally processed foods, and discourage ultra-processed foods availability and accessibility in Mexico.

Adventist Health Study

The objective of this study was to use life cycle assessment to estimate the environmental impacts (from farm to factory gate) of the 198 hard-coded line-items included in the food frequency questionnaire of the Adventist Health Study-2 survey and to assess differences among food groups. Life cycle inventories were created using existing data sources and primary data, and their global warming potential (GWP), land use, and water consumption impacts were assessed using the ReCiPe 2016 methodology. In addition to presenting the impacts according to weight and protein content across food groups, we include the novel addition of presenting impacts according to the NOVA classification indicating various levels of processing. Food categories were compared based on one kilogram of edible food, protein food sources were compared based on one kilogram of protein, and NOVA comparisons were based on one serving. In general, meats had the highest environmental impacts per both weight and protein content, while the lowest overall impacts per kilogram came from fruits. Meat analogs had the lowest overall impacts per kilogram of protein, contrary to expectations that additional processing would result in higher environmental impacts when compared to whole plant-based foods. Per serving, ultra-processed foods had the highest GWP, processed foods the highest land use, and minimally processed foods the highest water consumption. Results from this analysis were consistent with other studies. Results from this study suggest that meat and ultra-processed foods have the overall worst environmental impacts, but high water consumption in some minimally processed foods means that those should be carefully considered as well.

Background. Highly processed foods are inexpensive and abundant in our food supply, nutritionally poor, and disproportionately marketed to minority youth. This study is part of a curriculum development project to develop, implement, and evaluate the In Defense of Food (IDOF) curriculum designed to increase intake of whole/minimally processed foods and decrease intake of highly processed foods in youth. Aims. This pilot outcome evaluation was undertaken to assess initial effectiveness and to provide an in-depth understanding of changes in behavioral outcomes and psychosocial mediators. Methods. We used an explanatory mixed method approach, including a single-arm pretest–posttest of intervention effect, followed by a food rules assessment and in-depth interviews to describe participant responses to the intervention in more detail. The study was conducted in three afterschool classrooms in urban low-income neighborhoods with 32 multiethnic middle-school youth, receiving 10 weekly 2-hour sessions. Results. Two weeks postintervention, there was a large positive significant increase in whole/minimally processed food intake ( p < .01; d = 0.59) and a small decrease in consumption of highly-processed foods ( p = ns; d = 0.06), compared with baseline. Significant increases in psychosocial mediators: Self-efficacy and positive outcomes expectations were seen; others were not significant but changed in the desired direction. Qualitative assessments suggest that the intervention promoted skill building, but environmental barriers made these difficult to use. Discussion. The IDOF curriculum may be most effective for promoting consumption of fruits and vegetables, rather than decreasing intake of highly processed foods. In addition, in this young age-group, short actionable food rules may support self-regulation and behavior change. Conclusion. Among adolescent students in low-income urban neighborhoods, the IDOF afterschool curriculum may help promote self-efficacy and positive outcome expectancies and increase fruit and vegetable intake. Focusing on food processing and using “Food Rules” may be promising to elicit behavior change in youth; however, greater supports are needed to overcome social and environmental barriers.

ABSTRACT Objective: To compare and analyze the consumption of minimally processed and ultra-processed foods among students from public and private schools. Methods: Study conducted in Uberlândia, MG, with fifth-grade students from three private and six public schools, selected by stratified cluster sampling. We collected data on food consumption using the 24-hour recall. Foods were classified into four groups (G) according to extent and purpose of processing: fresh/minimally processed foods (G1) culinary ingredients (G2), processed foods (G3), and ultra-processed foods (G4). Total energy intake (kcal) of each group, amount of sugar (g), sodium (mg), and fiber (g) were quantified and compared according to administrative affiliation (private or public). Results: Percentage of total energy intake was: G1 - 52%; G2 - 12%; G3 - 5%; e G4 - 31%. Energy intake from G1 (53 vs. 47%), G2 (12 vs. 9%), and G3 (6.0 vs. 0.1%), and amount of sodium (3,293 vs. 2,724 mg) and fiber (23 vs. 18 g) were higher among students from public schools. Energy intake from G4 (36 vs. 28%) and amount of sugar (20 vs. 14%) were higher among students from private schools. The consumption of foods from G1 in the school environment was higher among students from public schools (40 vs. 9%). Conclusions: Foods from G1 represent the highest percentage of total energy intake, while those from G4 constitute a third of calories consumed. Processed juice, sandwich cookie, processed cake, and breakfast cereals are more frequent among private school students; snacks and juice powder are more common for students from public schools.
