The total dietary intake of energy and of individual nutrients of 99 grades 3 and 6 children from 10 greater Winnipeg shcools were generally comparable to those reported by Nutrition Canada for the Manitoba and national samples, although the percentile distributions of total caloric intake and dietary intake of vitamin A for the Winnipeg children tended to be lower. The median daily intake of protein was 212% of the Canadian Dietary Standard and most came from animal sources. Dietary fat was largely from animal sources as well. Hemoglobin concentrations were marginally low in four children, and urinary riboflavin:creatinine ratios were low in six children. There was no biochemical evidence of thiamin deficiency. The results suggest a need for change in dietary patterns and for education in nutrition, including relative nutrient/cost benefits. A well planned school snack program with an education component is a medium by which change could be introduced. This should preferable be part of a total school health program.
来自温尼伯市10所学校的99名三年级和六年级儿童的能量及各类营养素的膳食总摄入量，总体上与加拿大营养局报告的曼尼托巴省及全国样本的摄入量相当，不过温尼伯儿童的总热量摄入及维生素A膳食摄入量的百分位数分布往往较低。蛋白质的每日摄入量中位数为加拿大膳食标准的212%，且大部分来自动物来源。膳食脂肪也主要来自动物来源。4名儿童的血红蛋白浓度略低，6名儿童的尿核黄素：肌酐比值较低。没有硫胺素缺乏的生化证据。结果表明需要改变饮食模式并开展营养教育，包括相对营养素/成本效益。一个精心规划且带有教育成分的学校零食计划是引入改变的一个途径。这最好成为整个学校健康计划的一部分。
