OBJECTIVE
To estimate the contribution of energy and selected nutrients from foods eaten as snacks and as meals.
SUBJECTS AND METHODS
Forty-four nonpregnant women in the reproductive age, of whom 20 were lactating, participated in this study. Women from rural households were randomly selected and energy and nutrient intakes were estimated using 2 days' observed weighed food record. Snacks eaten between meals were estimated by weighed food record as well as recall, thrice per day.
RESULTS
The largest proportions (mean+/-s.e.) of fat (33+/-3.6%), vitamin C (36+/-4.1%) and a large proportion of vitamin A (30+/-4.4%) intakes were from snacks. Furthermore, snacks provided 20% of the energy intakes.
CONCLUSION
Snacks are important for energy and nutrient intakes and adequacies in rural African women and have the potential to combat energy and nutrient deficiencies in low-income countries.
目的
评估零食和正餐所摄入食物中的能量及特定营养素的贡献。
对象与方法
44名处于生育年龄的非孕妇女参与了本研究，其中20名正在哺乳。从农村家庭中随机选取妇女，通过连续2天的食物称重记录来估算能量和营养素摄入量。餐间食用的零食通过食物称重记录以及每天3次的回忆法进行估算。
结果
脂肪摄入量的最大占比（均值±标准误）为（33±3.6%），维生素C为（36±4.1%），维生素A的很大一部分占比为（30±4.4%），这些均来自零食。此外，零食提供了20%的能量摄入量。
结论
零食对于非洲农村妇女的能量和营养素摄入及充足性而言非常重要，并且在低收入国家有潜力对抗能量和营养素缺乏问题。
