To identify major food sources of nutrients and dietary constituents for US children.
Twenty-four-hour dietary recalls were collected from a nationally representative sample of children age 2 to 18 years (n = 4008) from the US Department of Agriculture's 1989-1991 Continuing Survey of Food Intakes by Individuals. For each of 16 dietary constituents, the contribution of each of 113 food groups was obtained by summing the amount provided by the food group for all individuals and dividing by total intake from all food groups for all individuals.
Milk, yeast bread, cakes/cookies/quick breads/donuts, beef, and cheese are among the top 10 sources of energy, fat, and protein. Many of the top 10 sources of carbohydrate (yeast bread, soft drinks/sodas, milk, ready-to-eat cereal, cakes/cookies/quick breads/donuts, sugars/syrups/jams, fruit drinks, pasta, white potatoes); protein (poultry, ready-to-eat cereal, pasta); and fat (potato chips/corn chips/popcorn) also contributed >2% each to energy intakes. Ready-to-eat cereal is among the top contributors to folate, vitamin A, vitamin C, iron, and zinc intakes. Fruit drinks, containing little juice, contribute approximately 14% of total vitamin C intakes.
Fortified foods are influential contributors to many vitamins and minerals. Low nutrient-dense foods are major contributors to energy, fats, and carbohydrate. This compromises intakes of more nutritious foods and may impede compliance with current dietary guidance.
确定美国儿童营养素和膳食成分的主要食物来源。
从美国农业部1989 - 1991年个人食物摄入量持续调查中,收集了具有全国代表性的2至18岁儿童样本(n = 4008)的24小时膳食回忆。对于16种膳食成分中的每一种,通过汇总所有个体中该食物组提供的量,并除以所有个体从所有食物组的总摄入量,得出113个食物组中每组的贡献。
牛奶、酵母面包、蛋糕/曲奇/快速面包/甜甜圈、牛肉和奶酪是能量、脂肪和蛋白质的前十大来源。碳水化合物的前十大来源(酵母面包、软饮料/汽水、牛奶、即食谷物、蛋糕/曲奇/快速面包/甜甜圈、糖/糖浆/果酱、果汁饮料、面食、白土豆);蛋白质(家禽、即食谷物、面食);以及脂肪(薯片/玉米片/爆米花)对能量摄入的贡献也均超过2%。即食谷物是叶酸、维生素A、维生素C、铁和锌摄入量的主要贡献者之一。几乎不含果汁的果汁饮料约占维生素C总摄入量的14%。
强化食品是许多维生素和矿物质的重要贡献者。低营养密度食物是能量、脂肪和碳水化合物的主要贡献者。这不利于更有营养食物的摄入,可能会妨碍遵循当前的饮食指南。
