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.
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.
Guasaganda, Cotopaxi (Ecuador).
Rural, indigenous adult women, non-pregnant and not breast-feeding.
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).
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.
通过在厄瓜多尔农村进行饮食摄入研究，评估传统食物（本地种植和野生）的饮食多样性和营养贡献。
在 14 天的间隔内重复进行 24 小时回忆和食用频率，以多源法模拟通常的饮食。使用多元链方程缺失访问数据（n 11）进行插补。报告了三种宏量营养素和六种微量营养素的摄入量。使用营养素充足率、平均充足率（MAR）、饮食物种丰富度（DSR）和女性最低饮食多样性来衡量饮食质量。使用线性分位数混合模型研究 DSR、本地物种、MAR、年龄、教育和职业之间的关系。
瓜萨甘达，科托帕希（厄瓜多尔）。
瓜萨甘达农村地区的成年、土著、非怀孕和非哺乳期妇女。
研究饮食的 MAR 为 0.78。传统食物的摄入量占总能量摄入的 38.6%。满足了蛋白质、碳水化合物、铁和维生素 C 的日常需求。额外的本地物种消费与宏观营养素 MAR 中位数增加 0.033（P<0.001）相关。另一方面，额外的本地物种消费与微量营养素 MAR 中位数增加 0.052（P<0.001）相关。
我们发现有统计证据表明，传统食物有助于研究人群摄入足够的宏量和微量营养素，并实现饮食多样化。未来的公共卫生干预措施应促进传统食物的种植和消费，以提高当地饮食的质量。
