Concerns about adequate food supply is a mounting problem in Canada, making food bank visits a necessity for over 820,000 Canadians. Given this reliance, the purpose of this study was to compare contents of food hampers with Canadian guidelines, at a large urban food bank in Southwestern Ontario that intends to provide 3 days worth of food per person.
Thirty hampers of each available size (for 1-6 people) were sampled (N = 180). Food items were recorded and analyzed for caloric value, food group, and macro- and micro-nutrient values. Results were compared to Dietary Reference Intakes (DRI) and Canada's Food Guide to Healthy Eating.
99% of hampers did not provide 3 days worth of nutrients. Grains and cereals met the lower range of Canada's Food Guide recommendations, and fruits and vegetables, meats and alternatives, and dairy products were below recommended levels, as were numerous vitamins and minerals, including vitamins A, D, B12, C, riboflavin, niacin, calcium, magnesium and zinc. Carbohydrates were slightly above recommended DRI, and energy from fat and protein scarcely met the minimums recommended. Hampers contained 1.6 days worth of energy per person.
The energy available per person was below recommendations for most Canadians. Nutrients missing from the hampers can come from fresh fruits, vegetables, dairy products, and meats and alternatives. However, many low-income families have limited finances to purchase these foods which are relatively more expensive than processed foods. Encouraging more perishable food donations and storage facilities to maximize the nutritional intake for clients is imperative.
对充足食物供应的担忧在加拿大是一个日益严重的问题,使得超过82万加拿大人不得不求助于食物银行。鉴于这种依赖,本研究的目的是在安大略省西南部一家大型城市食物银行,比较食物篮中的食物内容与加拿大指南,该食物银行旨在为每人提供三天的食物量。
对每种可用尺寸(供1至6人使用)的30个食物篮进行抽样(N = 180)。记录食物项目并分析其热量值、食物类别以及宏量和微量营养素值。将结果与膳食参考摄入量(DRI)和加拿大健康饮食指南进行比较。
99%的食物篮未提供三天的营养素量。谷物和谷类食品达到了加拿大饮食指南建议范围的下限,而水果和蔬菜、肉类及替代品以及乳制品均低于建议水平,许多维生素和矿物质也是如此,包括维生素A、D、B12、C、核黄素、烟酸、钙、镁和锌。碳水化合物略高于推荐的DRI,来自脂肪和蛋白质的能量几乎未达到建议的最低值。食物篮每人提供的能量仅够1.6天。
对于大多数加拿大人来说,每人可获得的能量低于建议值。食物篮中缺少的营养素可来自新鲜水果、蔬菜、乳制品以及肉类和替代品。然而,许多低收入家庭资金有限,无法购买这些相对比加工食品更昂贵的食物。鼓励更多易腐食品捐赠并提供储存设施,以最大限度地提高客户的营养摄入量势在必行。
