To examine the temporal pattern of the number of eating occasions that occurred at home, at work and outside the home, and to examine the contribution of fat to energy and the contribution of 26 food groups to fat at home and outside the home.
Food intake data were collected using a 7-day food diary from a random sample of 18-64-year-old adults from the Republic of Ireland (n=958). Respondents recorded the day, time and location of every eating occasion.
The number of eating occasions was constant across the days of the week for meals consumed at home, whereas the number of eating occasions increased at weekends for meals outside the home. The contribution of fat to energy approximated the 35% recommendation at home from Monday to Friday, but increased above this on Saturday and Sunday. The contribution of fat to energy outside the home was always above the recommendation. The food groups that contributed most to fat were similar at home and outside the home. These included butter and full-fat spreads, fresh meat, meat products, meat dishes, biscuits, cakes and pastries, whole milk, and chips and processed potatoes.
The contribution of fat to energy was above the recommendations when eating outside the home, regardless of day of the week. A number of food groups have been identified that contributed most to fat intake outside the home and these might be targeted in developing public health nutrition strategies to reduce fat intake.
研究在家中、工作场所及家庭以外场所进食次数的时间模式,以及脂肪对能量的贡献,和26种食物类别在家中和家庭以外场所对脂肪的贡献。
采用7天食物日记收集来自爱尔兰共和国18 - 64岁成年人随机样本(n = 958)的食物摄入数据。受访者记录每次进食的日期、时间和地点。
在家中进食的次数在一周各天保持不变,而在家庭以外场所进食的次数在周末增加。周一至周五在家中脂肪对能量的贡献接近35%的推荐值,但在周六和周日高于此值。在家庭以外场所脂肪对能量的贡献始终高于推荐值。在家中和家庭以外场所对脂肪贡献最大的食物类别相似。这些包括黄油和全脂涂抹酱、鲜肉、肉制品、肉类菜肴、饼干、蛋糕和糕点、全脂牛奶,以及薯片和加工过的土豆。
无论一周中的哪一天,在家庭以外场所进食时脂肪对能量的贡献高于推荐值。已确定了一些对家庭以外场所脂肪摄入贡献最大的食物类别,在制定公共卫生营养策略以减少脂肪摄入时可针对这些类别。
