RESUMO
OBJECTIVE: To evaluate the dietary diversity and the nutrient contribution of traditional foods (locally cultivated and wild) by conducting a food intake study in rural Ecuador. DESIGN: Repeated 24 h recalls over a 14 d interval and frequency of consumption served to simulate the usual diet by the Multiple Source Method. Data on missing visits (n 11) were imputed using multivariate imputation by chained equations. The intakes of three macro- and six micronutrients were reported. Nutrient Adequacy Ratios, Mean Adequacy Ratio (MAR), Dietary Species Richness (DSR) and Minimum Dietary Diversity for Women were used as measures of dietary quality. A linear quantile mixed model was used to investigate the association between DSR, local species, MAR, age, education and occupation. SETTING: Guasaganda, Cotopaxi (Ecuador). PARTICIPANTS: Rural, indigenous adult women, non-pregnant and not breast-feeding. RESULTS: The studied diet had MAR of 0·78. Consumption of traditional foods contributed 38·6 % of total energy intake. Daily requirements for protein, carbohydrates, Fe and vitamin C were reached. An extra level of consumption of local species was associated with an increase in median MAR for macronutrients of 0·033 (P < 0·001). On the other hand, an extra level of consumption of local species was associated with an increase in median MAR for micronutrients of 0·052 (P < 0·001). CONCLUSIONS: We found statistical evidence that traditional foods contribute to adequate intakes of macro- and micronutrients and dietary diversification in the studied population. Future public health interventions should promote the cultivation and consumption of traditional foods to increase the quality of the local diet.

OBJECTIVE: To document the perceptions of indigenous peoples for the sustainable management of natural resources against malnutrition. DESIGN: Initially 4 and then 12 interviews were conducted with 4 different age groups. SETTING: Eight rural villages in Guasaganda, central Ecuador, were studied in 2011-2012. PARTICIPANTS: A total of 75 people (22 children, 18 adolescents, 20 adults, and 15 elders). MAIN OUTCOME MEASURES: Benefits, severity, susceptibility, barriers, cues to action, and self-efficacy of eating traditional foods. ANALYSIS: Qualitative content analysis was completed using NVivo software. Initial analysis was inductive, followed by a content analysis directed by the Health Belief Model. Coding was completed independently by 2 researchers and kappa statistics (κ ≥ 0.65) were used to evaluate agreement. RESULTS: Healthy perceptions toward traditional foods existed and differed by age. Local young people ate traditional foods for their health benefits and good taste; adults cultivated traditional foods that had an economic benefit. Traditional knowledge used for consumption and cultivation of traditional foods was present but needs to be disseminated. CONCLUSIONS AND IMPLICATIONS: Nutrition education in schools is needed that supports traditional knowledge in younger groups and prevents dietary changes toward unhealthy eating. Increased production of traditional food is needed to address current economic realities.
