As part of the 16-17 year follow-up of the 1970 longitudinal birth cohort study, The International Centre for Child Studies collected dietary data from a National sample of 4760 teenagers. Dietary intake data were collected in 4 d unweighed dietary diaries, distributed by schools and returned by post. Dietary intake data were quantitatively coded, and the intakes of energy, macronutrients and non-starch polysaccharides (NSP) are reported. Intakes of fat and extrinsic sugars, expressed as a percentage of energy intake, exceeded recent recommendations (Department of Health, 1991), and the intakes of intrinsic sugars, milk sugars and starch, and NSP were considerably lower than recommended. Only 25% of males and 10% of females achieved intakes of 18 g NSP/d. The main food groups contributing fat (%) to the diets of teenagers (for males and females respectively) were meat and meat products (24.2, 22.1), spreading fats (18.6, 18.1) and cereals and cereal products (18, 17.8), whilst the major sources of sugars (%) were (for males and females respectively) sugar and confectionary (28.2, 26.4), cereals and cereal products (24.5, 23) and beverages (21.9, 21.5). Less than half the cohort drank alcohol during the recording period, and about 6% of females drank more than 2 units alcohol/d, and about 6% of males drank more than 3 units alcohol/d.
作为1970年纵向出生队列研究16 - 17年随访的一部分，国际儿童研究中心收集了来自4760名青少年全国样本的饮食数据。饮食摄入数据通过学校发放并邮寄回收的4天非称重饮食日记来收集。饮食摄入数据进行了定量编码，并报告了能量、宏量营养素和非淀粉多糖（NSP）的摄入量。以能量摄入百分比表示的脂肪和添加糖摄入量超过了近期建议水平（卫生部，1991年），而内源性糖、乳糖和淀粉以及NSP的摄入量则远低于建议水平。只有25%的男性和10%的女性达到了每日18克NSP的摄入量。青少年饮食中脂肪（%）的主要食物来源（分别针对男性和女性）是肉类及肉制品（24.2、22.1）、涂抹脂肪（18.6、18.1）和谷物及谷物制品（18、17.8），而糖（%）的主要来源（分别针对男性和女性）是糖及糖果（28.2、26.4）、谷物及谷物制品（24.5、23）和饮料（21.9、21.5）。在记录期间，不到一半的队列成员饮酒，约6%的女性每天饮酒超过2单位，约6%的男性每天饮酒超过3单位。
