High saturated fat intake is an established risk factor for several chronic diseases. The objective of the present study is to report dietary intakes and main food sources of fat and fatty acids (FA) from the first year of the National Diet and Nutrition Survey (NDNS) rolling programme in the UK. Dietary data were collected using 4 d estimated food diaries (n 896) and compared with dietary reference values (DRV) and previous NDNS results. Total fat provided 34-36 % food energy (FE) across all age groups, which was similar to previous surveys for adults. Men (19-64 years) and older girls (11-18 years) had mean intakes just above the DRV, while all other groups had mean total fat intakes of < 35 % FE. SFA intakes were lower compared with previous surveys, ranging from 13 to 15 % FE, but still above the DRV. Mean MUFA intakes were 12·5 % FE for adults and children aged 4-18 years and all were below the DRV. Mean n-3 PUFA intake represented 0·7-1·1 % FE. Compared with previous survey data, the direction of change for n-3 PUFA was upwards for all age groups, although the differences in absolute terms were very small. Trans-FA intakes were lower than in previous NDNS and were less than 2 g/d for all age groups, representing 0·8 % FE and lower than the DRV in all age groups. In conclusion, dietary intake of fat and FA is moving towards recommended levels for the UK population. However, there remains room for considerable further improvement.
高饱和脂肪摄入量是多种慢性疾病的既定危险因素。本研究的目的是报告英国国家饮食与营养调查(NDNS)滚动项目第一年的脂肪和脂肪酸(FA)的饮食摄入量和主要食物来源。使用 4 天估计食物日记(n=896)收集饮食数据,并与饮食参考值(DRV)和之前的 NDNS 结果进行比较。所有年龄段的总脂肪提供 34-36%的食物能量(FE),与之前的成人调查相似。男性(19-64 岁)和年龄较大的女孩(11-18 岁)的平均摄入量略高于 DRV,而所有其他组的总脂肪摄入量均低于 35%FE。与之前的调查相比,SFA 的摄入量较低,范围为 13-15%FE,但仍高于 DRV。成年人和 4-18 岁儿童的 MUFA 平均摄入量为 12.5%FE,所有摄入量均低于 DRV。n-3PUFA 的平均摄入量占 FE 的 0.7-1.1%。与之前的调查数据相比,所有年龄段 n-3PUFA 的变化方向均为上升,尽管绝对值差异非常小。反式脂肪的摄入量低于之前的 NDNS,所有年龄段的摄入量均低于 2g/d,占 FE 的 0.8%,在所有年龄段均低于 DRV。总之,脂肪和 FA 的饮食摄入量正在朝着英国人口的建议水平发展。然而,仍有相当大的进一步改进的空间。
